These look like real hardware to me.

Anything interesting in the output of 'lspci -nn', 'lsusb' and 'dmesg'?

Ah, that's probably why I stuck with the long form when I started using 
it. I'm guessing I was bit by my habit of adding options as I read 
through the man page (and du(1) has them mostly in alphabetic order).

Will start retraining my fingers ;)

Care the elaborate on this? The software in stable at release is already 
quite mature.

What is the point of waiting ~2 additional years for stable to become 
oldstable?

Few bugs (if any) besides security bugs are fixed in stable, and 
oldstable has full security support only one year after the stable 
release.

Exactly. "Hey, won't *everybody* switch to using  for

Besides the social part of asking *everybody* *else* to switch I'm also

I'd say it is a Linode problem, unless you run custom kernel modules.
It looks like a "memory" corruption to me and since it is virtualized 
system, you should check if host system is ok.
Memory in quotes because this issue could be also related to a storage 
sub-system (local or network attached) of the host or VM.

This is the problem with the word Proprietary in Proprietary software.
So far as the Collective, Mutually Empowering Choice offered us humans
with the advent of FSF GNU-Linux, we missed the boat of Empowering the
Social Contract collectively. I continue to lament our poor choice for
this illusory threat of theft of personal information (or Zero Sum
Hawk-Dove Power Games?), which only in a minority of cases, could be
justified.

It is only because of a few individuals who still believe in the
robustness in the FSF and Open Source architecture that we remain what
we were supposed to be.

I must admit that I haven't looked at ALSA for quite some years and
I consider computers to be devices which should ideally stay silent, so
my knowledge of audio is quite limited, but I've recorded the "Monitor"
of the output with good success when recording a Jitsi session (using
`vokoscreen`, IIRC).

Admittedly, I was using pulseaudio, so maybe this is a PA feature not
available in ALSA?

I don't know what Debian or kernel the OP is running.

Googling linux kernel wwan device throws up
https://lore.kernel.org/netdev/20200225105149.59963c95aa29.Id0e40565452d0d5bb9ce5cc00b8755ec96db8559@changeid/
which suggests a mobilephone-type device.

BTW /etc/udev/rules.d will only be populated if you put your own stuff
there (like I do); it belongs to the sysadmin. The system uses /lib
and /run.

Cheers,
David.

I wouldn't say that I particularly know more; in fact I may know less.

However, if I were encountering such symptoms and had (as has apparently
happened here) searched the system for mention of the key term 'wwan'
without finding it, the next places I'd look for clues would be A: dmesg
and B: the contents of /var/log/. (If running systemd, I'd probably also
want to investigate the contents of the journal, but I don't know proper
syntax for that beyond the name 'journalctl'.)

It might be necessary to make sure you're booting with appropriate
message verbosity; IIRC, systemd may default to a quieter boot than
sysvinit does, so you may have to adjust some grub parameters and
reboot. In principle, however, I'd expect that if such devices are being
set up at boot time there'd have to be some details about that logged
during the boot process, and such logging would have to go to one or
more of those three places.

I have 2 machines here running Debian 10.8, they're both empty
like yours, so I don't think that's any problem.

I remember that udev used to manage interface names, but it seems that
it is not involved here, so we eliminated that possibility.

So I guess the answer is either in the kernel, or systemd,
but I don't know, and I found no further clues about that in

I (≠ OP) don't use pulseaudio as a matter of course. It's meant to
give benefits, but can add undesired complexity. So I generally
stick with ALSA.

The downside, though, is that although alsamixer may show that there's
a Capture device (slider) in the Capture (F4) window, it will only
record sounds from the Microphone, and not from, say, the browser.

Most of the time, this doesn't matter, as I have developed several
techniques over the years for capturing Transport Stream files from
the cache, and assembling them into seamless live video, and even
slurping files out of the browser's /proc//fd thingies when
youtube_dl fails to download a video.

But nowadays, there are some audio links that play quite happily
without leaving any trace that I can find. Which leaves only the
option of recording the soundcard output. Some computers have both
LineOut and LineIn, and these can be connected together, but that's
not a very good solution in terms of noise.

My latest acquisition, a Dell Precision T3500, fell into my lap just
as my old Pentium III (Yamaha ymf740c) expired, and has the similar
ability to record from the browser (I suppose that's the PCM). It's
as tedious as recording from, say, vinyl, as you have to top, tail,
and possibly split all the recordings you make. There's also the
business of setting levels, and so on; all unnecessary operations
if only you could grab the digital output.

But it's the best I can manage. Fortunately I haven't met this
problem with videos that I want, only audio recordings.

Any idea what technologies are being used by these websites?
I don't want to give examples as I'm not sure they condone
recording their output, and some of the credentials I use are
decidedly ancient and technically should have been expired.
(I think of myself as a visiting alumnus.)

> You should describe what you are doing. I doubt PA has to do something with

I've read that PA is supposed to be able to make connections in
software that aren't offered by the hardware, rather like JACK
is also meant to do. I'm guessing that might be the OP's interest.

> What applications and how are they accessing your audio device.

In my case, that's FF. I sometimes read here that FF needs PA to
produce sound from webpages, but I've never found that to be so.
I do usually have to fiddle with magic spells to share ALSA (with
~/.alsa-configs/asound.conf), allowing two users' browsers (FF),
and their own mpv programs, all to play videos simultaneously on
one Xserver. (IOW an almighty cacophony.)

I hope my use case is close enough to the OP's to be a useful sidebar.

Cheers,
David.

I've always assumed that each driver (module) knows how to load
its own firmware into its own hardware in its own special way.
I've never tried going back and forth, but even if the firmware
remains in the device, there's little to be gained by not reloading
it, and a lot more to be gained by refreshing it (like updating it).

A network connection for ETHO on QEMU.

[peter]

No problem running ETHO on QEMU in Debian 10.

Creation of a network connection from the ETHO guest system to the 
QEMU host is giving difficulty.

I expect to use the NetNe2000 driver.

Should the guest system be connected as a routed subnet? 

Connected by a bridge?

This qemu command fails as follows.

alias etho='qemu-system-i386 \
 -drive file=/dev/KingstonCF,media=disk,format=raw \
 -vga std \
 -boot order=c \
 -netdev bridge,id=bridge0,br=br0 \
 -device ne2k_pci,netdev=bridge0 \
 '

peter@joule:/home/peter$ etho
failed to parse default acl file `/etc/qemu/bridge.conf'
qemu-system-i386: bridge helper failed

Ideas?

Thanks,   ... P. L.

You should describe what you are doing. I doubt PA has to do something with

non-existing interface problem

[ghe2001]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Buster, Dell laptop

I've got what might be two ghost interfaces, and I think I'd like to get rid of 
them.

I use /etc/network/interfaces to configure interfaces.  I have eth0 and eth0:1 
static, and wlan0 DHCP interfaces in the interfaces file.  Everything works 
properly.  The box is on two nets and acts as I expect it to.

ifconfig shows eth1 and wwan0 (yes wwan0, not wlan) as existing, but down, 
interfaces.  It claims eth1 has an Ethernet address (10:05:01:49:64:9d) -- 
similar to eth0's (10:05:01:40:f4:43).  Neither eth1 or wwan0 exist, as far as 
I know.  They aren't mentioned in my interfaces file, and there's just one 
Ethernet hole on the computer.  On the outside, anyway.  Webmin shown them in 
its list of existing interfaces, but they're greyed out and I can't access them 
(Webmin also says they're down).


root@gobook3:/# ifconfig eth1 up
doesn't complain, but afterward, it says it's not up:

root@gobook3:/# ifconfig eth1
eth1: flags=4099  mtu 1500
ether 10:05:01:49:64:9d  txqueuelen 1000  (Ethernet)
RX packets 0  bytes 0 (0.0 B)
RX errors 0  dropped 0  overruns 0  frame 0
TX packets 0  bytes 0 (0.0 B)
TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


ifconfig assigns eth1 an address if asked to:
root@gobook3:/# ifconfig eth1 42.42.42.42

root@gobook3:/# ifconfig eth1
eth1: flags=4099  mtu 1500
inet 42.42.42.42  netmask 255.0.0.0  broadcast 42.255.255.255
...

And Webmin shows eth1 with the IP and up.  And it's accessible now.


But ifup:

root@gobook3:/# ifup eth1
ifup: unknown interface eth1


They don't really seem to hurt anything because they're never expected to be 
active (and they certainly aren't), but I'd like to get rid of them.  They're a 
little sloppy  in my configs, and they might bite me in the ass someday.

I've looked for several things on the web, and grepped for wwan on the disk to 
no avail.  This confusion doesn't exist on the Supermicro desktop.

Any help or suggestions would be appreciated.  Or maybe just an explanation of 
what's going on so I can quit worrying about it.

… those two things. I've used Disk Manager to stop assigning *any*
letter to my fixed disk linux partitions so that it doesn't nag my
wife about reformatting them.

Reading the OP's use of E: and F:, and storing device names in the
filesystem, I assumed that Stable/Remembered names was some ability of
Windows that the OP missed in linux. (Like much of the thread seems
to be.) Hence the exposition on my own scheme for stable mount points.

Yes, I wasn't discounting the system drive being a letter (C:),
but just pointing out the recent ability to make a hierarchy out of
Windows's C: D: E: F: disjointed filesystem.
(IOW "letters" stood for having all these separate "roots".)

It only works with the first level of attribution, because the next
person to quote the quote may have a different timezone in their header.

And that leaves aside the problem of attributions that have been
silently converted into the quoter's timezone, with or without a
new TZ being specified).

Plus, it does appear that there are MUAs that attribute the time
of a quote to the time at which the replier *started their reply*
to the original email, which is completely bizarre. (There are
several such MUAs posting here.)

Thank you two, and everyone else.  Now I can send this message from Debian.

I saw the network interface number 4 [1] after installing and running
the firmware only.
Then, dmesg showed that last line that told me the "wlan0" (i.e. the
wireless device)
was instead "wlx000d81af0249".

So, I opened Wicd one more time to see if something happened, I clicked on
preferences and saw that the wireless network interface field was empty.
I wondered what would happen if I wrote wlx000d81af0249 [1] there.
So I did it and boom!  It works!

I wonder why Wicd doesn't detect the wireless interface automatically.
Was it designed to be configured manually or is it a bug?

Anyway, is there some way to automate this?  I saw there was that command
"ip link set  up" but it doesn't make Wicd recognize the interface
automatically.

I think some of you miss some of the advantages of Facebook.  It allows
me to stay loosely in touch with around 120 friends, many of whom I have
not seen face-to-face for maybe 30 years.  They can see I'm still alive and 
I them, and I'm able to feel just slightly more in-touch with them.

The overall effect is a bit like that of receiving a once-per-year round-robin
letter from each of them, except that instead of a whole wodge of news 
coming once per year, one gets - shall we say - a fiftieth of the amount 
50 times more often.

It also allows one to comment immediately on something someone else
has done, which requires a lot less commitment than a full conversation 
with someone whom, in fact, one perhaps no longer knows well.  

I would not expect most of these people ever to ring me, and by the 
same token I am not going to ring 120 people, who're now spread all
across the world.

How can "sheer luck" be a factor? My non-participation in Facebook
is due to a conscious decision.

Perhaps they feel a need to communicate with a group. That's hardly
being "sucked in". Their choice, just like mine. Different midsets.
To imply it is not quite the best and there is something that should
be done about such a choice is simply vi vs emacs talk :).

udevadm trigger is the command to run to simulate plugging in the wifi
adapter after you have the firmware available. I don't think modprobe
loads firmware.

Alternatively you can just unplug and plug the adapter after installing
the firmware.

But if you did this and it still doesn't work I'm pretty much out of
ideas. Does dmesg report anything relevant to network or realtek? For
example I get this when my new system boots:

r8169 :03:00.0: firmware: direct-loading firmware rtl_nic/rtl8125b-2.fw

You can use the short option -d instead of --max-depth, and make it's
parameter '1' come straight after [1], so my go-to command for tracking
down where disk space is been used is...

du -hd1 | sort -h

then 'cd' into a likely candidate directory and repeat.

[1] parameters for short options like this only works for last short
option in a joined list, e.g. -d1h is invalid.

As someone else mentioned in this thread, 'ncdu' is very convenient

I don't know whether that hard position is always viable. I mean,
I managed without Facebook (and *all* the others, btw.) but that
may well be sheer luck. To think otherwise would feel... arrogant

If they shun or ostracize you for not being on Facebook, they are 
neither your friends nor your family.


The very first thing I do when taking possession of a computer is to add 
host table entries to interdict any attempt to access Facebook or 
Twitter (by mapping them to 0.0.0.0). That way, it becomes impossible 
for me to be tricked into accessing them by disguised links (I have 
received such links a number of times).


I have real friends. And a real web site. And list-servers and boards. 
And a life.

That would work if I already had Debian with internet connection.

Did you reboot or had a complete umount / mount cycle in between?

I did the same thing - I resisted being on FB for a very long time,
but eventually I had to get on because it was how my family was
communicating and I was being left out of the loop. I joined as my dog
only my family knew how to find me. Even to this day I am only

I'm sorry, I don't know that difference.  I made some

Thank you! You did not mention this before.

Has it always done this, or is it new?

Are the programs faster after they have loaded, or is everything

It will be fixed automatically as soon as the installer is 
(automatically?) rebuilt with the current kernel version in bullseye.

This is a recurring issue with the installers based on testing and 
unstable and likely very difficult to fix.

When Facebook was in its infancy (at least in my country?) they were 
spamming my e-mail inviting me to join because two co-workers joined 
(and probably gave Facebook access to all their e-mail contacts).

In one of those e-mails, besides the names of the two co-workers and 
some other work related persons Facebook mentioned also the name of an 
acquaintance from my native city with no link (I was aware of) to my 
current workplace. That was creepy enough for me to resist creating an 
account for a very long time.

Eventually I had to give in, because I was being literally forgotten by 
a group of friends that were using Facebook for most of their 
communication (I was the only one without a Facebook account), so I did 
create an account under a fake name, tied to a new webmail address.

For WhatsApp I am "fortunate" enough that it's allowed on the company 
provided mobile phone, so at least I can keep it off my private one. 
I've only managed to "blackmail" some close family and friends to use 
Signal, though many of my (less important, unfortunately) contacts did 
sign up since WhatsApp tried to change their privacy policy, so I'm 
still hopeful.

Twitter didn't really catch on here, Facebook dominates almost 
completely with it's own share of users + Instagram and WhatsApp. 
Hopefully they'll be split, in which case I just *might* reconsider 
WhatsApp for private use.

/home partition filling immediately after recent sid upgrade

[Mitchell Laks]

Hi,

I recently upgraded a system that uses sid and the /home partition filled.

I then adjusted tune2fs -m 3 /dev/md1 to give myself  20 G of space.
Did nothing and next day already filled /home 100% again.
Same thing happened when i did  -m2.

Ok how to find the culprit ?

A long long time ago, this happened when my .xsession-error file grew
without bounds.
Does not seem to be this file.

Any one else seen this. How to find the monster space eater.

And please no snarky "don't use sid" remarks.
It is fun to play with the latest software.

tried  du -sh on /home/username /* etc.
ls -ltr tail
Thanks

Does the issue go away if you revert to the previous version?

Hi Dan, Yes, you are right, it is not a specific Debian issue.But I 
don't know where to ask for help. I'm having trouble finding reliable 
answers to configure this router.There are many videos on Youtube but 
with contradictory information.I searched on the TP-link website and 
posted a question on the forum but I didn't have an answer.I did what 
you suggested, but throughout the day the speed varies. So my 
question is, what a speed value mean if it varies throughout the day?


I think you're getting into fundamentals of how your internet is 
provided. I'm not a networking engineer, so some of the detail of the 
following might be off, but this is how I understand it to work. The 
most popular broadband around at the moment is ADSL. This is, in VERY 
broad strokes, an extension of the older analogue modem technology. 
But, instead of the data being modulated into audible sound, it's 
modulated into ultrasonic sound. Instead of dialling into a server 
halfway across the country, with ADSL the sound only needs to carry as 
far as your local telephone exchange. Blocks of frequency, all above 
human hearing, are used and the total frequency range (and therefore 
data bandwidth) is MUCH higher than before. (Incidentally, because 
ADSL is fully above human hearing, this is why we can use a 
"microfilter" to split the data and voice frequencies, meaning you can 
use your phone without disrupting the internet).


Now, here is the first reason why the speed can vary throughout the 
day. ADSL is, fundamentally, trying to push wires which were only 
rated for voice frequencies beyond their limits. Sure, all data 
transmission technologies have an analogue medium, but Cat5e Ethernet 
cable is designed to fully handle the frequencies being passed across 
it. The copper phone lines to your telephone exchange might be half 
buried in water, they might run alongside a train track, they might 
follow the twisty route of a suburban road, rather than taking the 
most direct route. The upshot of this is that the amount of noise on 
your line probably isn't constant. Your ADSL modem will be constantly 
monitoring the signal-to-noise ratio of the various blocks of 
frequency, and the two ends will negotiate which to use. To put it 
simply, bad weather can reduce your bandwidth.


Another issue that might affect your speed is "contention". Contention 
is a more broadly-applicable issue. You see it on ADSL broadband, but 
you see it more commonly on Cable broadband. Contention basically 
means that some part of the connection between your house and the 
ISP's central servers is oversold. Taking the ADSL system as an 
example, let's put ourselves in the shoes of a fledgling ISP. We are 
provisioning a neighbourhood for ADSL. Let's say that, theoretically, 
ADSL can go up to 50Mbps per line and that there are 100 houses being 
served by this one exchange. That means we need a 5Gbps link between 
the exchange and our servers, right? But they're SO expensive! And, 
no-one's actually bought ADSL yet, let alone the "Top Speed" package. 
If we buy the 1Gbps link, we can save massively. So, people start 
buying  ADSL and they're getting 10Mbps speeds. Wow! That's fast 
compared to 56kbps! 20 people buy it. 50 people buy it. Excellent, 
we're still only at half the capacity of our big link. Oh, but here's 
a technology update and ADSL can now reach 25Mbps. As you can see, as 
more and more people buy ADSL, and the ADSL routers get cheaper and 
faster, the pressure on the uplink increases. Now, as this happens, 
your ADSL modem will still report the fast speed. As far as it's 
concerned, it's established a, say, 25Mbps connection with the 
telephone exchange. Now, if it's 3am, perhaps you CAN download at 
close to that speed. But what if it's 7pm? And it's the season finale 
of "Lilliput's Got Talent". Suddenly, you've got dozens of people 
trying to download masses of data. Everyone is still connected to the 
telephone exchange at high speed, but the over-sold uplink can't 
transfer all of that data, so everyone's bandwidth slows to a crawl.


So, what can you do about it? Well, you probably can't complain to

It seems to me you are proposing an additional level of indirection[1],

say exactly when or what version it was.

  it came on two of the 3.5 inch floppy drive disks.

  i had a Zenith Z-Note back then, i386 it didn't even have a 
math co-processor, my checkbook register shows i bought that
in July of '92.

  i booted it, played around for a few minutes and then that
was it.  while i had plenty of unix experience from computer
labs i didn't have any real reason to do anything with it for
home use.  i was mainly using the notebook for e-mail and
usenet and that was all on Win3.1

  i didn't start using linux and Debian on a daily basis
until sometime around slink or potato.  by then i had bought
a new Dell desktop computer (which i'm using the case from
for this computer).  i still had a booting win98 and winEXP
for some time after that but as time moved on i got things
switched over from Multiplan and a few other things i no
longer cared much about.


  songbird

a bit of humor

[songbird]

  i'm surely not perfect and with this new motherboard and CPU
i was happy with my initial setup of the board and those worked
to where i could put the machine back together.

  first i installed the few expansion USB boards i had extra as
really i would rather wear those out instead of the main plugs 
on the motherboard.  my old motherboard i had an extra 10 USB
ports added by these expansion boards but this motherboard only
allowed one each of the USB3 and USB2 expansions so that was 
what i did.

  then i put the motherboard in the case, plugged everything back 
in and got the drives wired in so they'd not flop around too much 
when i stood it back up.

  the fun part turned out to be that not all USB ports could be
used by certain devices (the motherboard would not boot correctly
and it would be complaining about not being able to find init).

  i figured that out, got things to boot as they were before (well
not really but that is a whole different issue having to do with
UEFI and this particular mobo) and then the last device to get
going was the USB speakers.

  they are an old set from back when i bought the Dell machine.
very good sounding speakers with a subwoofer.  the previous
machine just took the audio feed from the audio out jack.  so
of course that was the first one to try for this mobo too.  i 
plugged it in, turned everything back on.  hmm, sound was really 
strange, a lot of noise, no real volume.  i scratched my head 
and tried a few of the other audio ports available.  no real 
change.

  i was starting to think that i would have to send this mobo
back after all.  grr!  then i realized i had not pushed the 
audio jack plug in all the way.

  whew!  that was it.  sound works fine now as it usually did
before.

  hahaha...  :)  silly me.  :)

Amb el GNOME Software em surten totes aquestes actualitzacions
sense que jo faci res en particular:

- les d'apt
- les del flatpak
- les del fwupd

Diria que no surten les d'snapd, però aquestes s'instal·len

Això deu ser perquè quan reiniciï el sistema arrenqui amb l'opció
per instal·lar les actualitzacions enlloc d'arrencar el nucli de
linux, com faria normalment.

Jo m'ho vaig trobar per sopresa després de comprar el portàtil i
canviar el boot perquè utilitzés EFI (vaig clonar el disc del
portàtil antic per no reinstal·lar-ho tot de zero). Vull dir que
no vaig res en particular per configurar-ho, per això no sé si

Now a question, if I may: you don't seem OK with Facebook "claiming"
your name. Why do you still have an account with them?

About the time I had my first Linux (perhaps mine was a tad earlier:
I think RH wasn't around yet; Yggdrasil was a thing. My first distro
was SLS, on 30 diskettes. I bought the 386 DX40 with 4 MB (!) RAM

My memory may be failed, but I think the reason I have a Facebook
account is because I found they had my name listed. To this day, I
don't understand how websites get away with that. The first person who
finds your name gets to claim it as their own via that "Is this you?"
thing that they do. Some websites do the same thing for businesses,
too.

My Facebook is still hanging around for weeks like the one we just
had. I have two webpages to post over there. They'll be tagged with a,
"This is what I've been trying to tell everyone for fifteen years. I
haven't been lying nor exaggerating about the situation."

My "advocacy" moved to Twitter because it feels like there's a better
chance of reaching a wider audience. I used to do the hashtags on
Facebook, but it seemed a waste of time because I NEVER stumbled upon
anything written by anyone else. It never felt like there was room for
accidental meetings with others who might help further the expressing
of your concerns (for lack of a better way to put it).

So anyway...

I dunno. I guess "btrfs device remove" is used to detach a device from

Many filesystems have multiple copies of the superblock (e.g. UFS and ext*).

What surprised and worried me is the fact that they persisted after the
disk was converted to ZFS, and btrfs continued to recognize this
filesystem as its own (albeit unmounted).

More or less what I do. I do sometimes visit Facebook, but with a highly
restricted browser profile: no javascript [1], no cookies. Most of the
FB page doesn't work properly, but it's mostly enough to get the info
I wanted.

Twitter? I go to a proxy, nitter [2]. Most of the things out there I do
with my restricted browser profile. If a page doesn't work, I just assume
they don't want to play with me.

And oh, some of the funny google services are in my /etc/hosts, pointing
to 127.0.0.1 

No, it ain't paranoia. If "they" [TM] want to get me, they just smash
down my door and get me, let's face it. Call it a sociological experiment:
I want to know how much life there is beyond surveillance capitalism :)

A revolt I started at my place in 1998 when I built my first "PC" and 
installed Red Hat 5.0 on it. There's a bounty on winderzs at my place, I 
always have a current debian based dvd handy to install a real OS on 
anything that crosses into my domain.

I came up to computers with an RCA Super Elf with an RBA 1802 cpu in 
1978, bought the kids a timex about the same time, made a detour to a TI 
99-4A, but found my salvation in the moto 6809 and an os running on a 
TRS-80 Color Computer called OS-9 at the time, a mini-unix thar ran fine 
in 64k of memory. Then had a full blown amiga for several years before I 
built that PC. Getting ready to retire but knowing I would be playing 
visiting fireman at other broadcast facilities also owned by a good but 
now departed friend, I bought an hp lappy in 2002, took me about a week 
to put Mandrake on it because the xp it came with couldn't make the 
hardware or radio network work.

Today I own one copy of win 10 home because its gfx will display a smith 
chart of an AM tower for a piece of test gear I own, called a Vector 
Network Analyzer. Win 10 is an improvement over xp, but its still the 
clunkyist os around, linux runs with far more security, smoother and I'm 
the boss, not some SOB in Redmond that had the chutspah to call me a 
pie-rat because I was pissed their network drivers didn't work.

Now that same SOB wants to kill off most of the planets population, 
saying its about the right balance at 250-300 million.

I thought it should be fixed under warranty, my mistake. Mandrake did 
make it all work.

I am enough of a JOAT I don't buy the extended warranty.  Hell, at my 
age, I don't even buy green bananas. Besides that, way too much suger 
for this aging and fading diabetic.

Take care, Tomas and stay safe and well.

I can go one better than that.

Unless my memory is failing me, I have only ever visited facebook.com
once in my life - and that was a mistake, I clicked on a link to
something that looked interesting without first checking the target domain.

I decided long, long ago (sometime in the first half of the first decade
of this century, IIRC) that I didn't trust Facebook - initially because
it and its embedded ads were a notorious vector for malware, later
because I just didn't trust it period. I made a conscious decision to
never risk visiting the site, and with that one exception (for which I
did have NoScript active) I'm fairly sure I've never broken from that.

I'm not as strongly antipathetic towards the other social-media sites,
but I still tend not to visit them. I do have a Twitter account
nowadays, but I rarely visit it, and the number of tweets I've sent out
is in the low double (or maybe even high single) digits.

My new knowledge after 5 seconds of searching, ...

https://en.wikipedia.org/wiki/Btrfs#Superblock
says that there are multiple copies of the superblock.

And the on-disk format is here:
  https://btrfs.wiki.kernel.org/index.php/On-disk_Format

And maybe if the drive was once part of a multiple
device filesystem it might be referenced in superblocks
on other devices.

Basically, there's an internal device ID list (hexadecimal GUIDs, if I'm
not mistaken), and a mapping in the Registry. Beyond that it probably
involves the internal device paths which underlie e.g. devmgmt.msc
(Device Manager), and I've only recently begun to learn about that
syntax in the first place.

For fixed disks, no letter is assigned by default, one has to be set up
explicitly. The GUI tool for doing this is diskmgmt.msc, and I believe
it can also be done using command-line tools that I've rarely had
occasion to touch.

For removable disks (e.g. USB drives), whenever a new one is connected
the next currently-not-known-used letter is assigned, for a definition
of "used" that doesn't count letters taken up by being mapped to network
drives. *Usually* it seems to recognize a previously-connected drive and
assign it the same letter as it got before, but not always; I've yet to
identify any recognizable pattern to how it handles things when two
drives previously got the same letter and you connect them both.

I'm not entirely sure how you're defining this.

Fixed disks basically always get the same letter. Removable ones only
sometimes do.

I can't completely swear to this, but I believe it's one of two things:
either whichever one gets connected first gets the letter and the other
one doesn't show up except in e.g. diskmgmt.msc (and an error is
probably logged), or whichever one gets connected second gets a
different letter automatically.

The exception is for letters consumed by network drives. If you have
e.g. enough USB drives connected for one of them to automatically get
the letter G:, and you already have G: mapped to a network location,
Windows will silently allow the network location to take precedence;
diskmgmt.msc will show the drive-letter mapping of the USB drive and
allow you to change it, but otherwise it will mostly look as if the
drive wasn't recognized in the first place.

You still have to have the letters, or at least "letter" singular, so
that you have a place to create directories onto which to do the
mounting. Other than that, yes, this is possible.


To be clear: I think this entire proposal (except for the part about how
Windows should automatically proceed to AA: after hitting Z:) is
wrongheaded, not worth the effort, virtually certain to never be
implemented in practice, and would cause far more problems than it would
solve. As a thought exercise it is interesting, but primarily for how it
helps us dig up and see the problems which would result from trying to
implement it.

Yeah I expect you're supposed to 'btrfs remove' before
replacing the filesystem with something different.

No. It just told me the offset, but I have no idea what is located at
that offset, and this can be important.

So what is that at 0xff6? GPT, MBR, some superblock, some reserved sector?

Well, the FS (btrfs in this case) was not there already, but the magic
label was still there somewhere.

As I said, the FS had already been replaced by another FS. 

I would usually wipe the first several MB of a disk with dd when I
change filesystems or disk partitioning schemes, but this
one was already in production.

Well, to search Duckduckgo for wipefs, you need to know about wipefs :-)
I found it from reading man blkid and lsblk, after that the information
from wipefs(8) turned out sufficient (and the howto above did not add
any new knowledge).
