Bug with lib ssl

[Fabrice Vaillant]

Hey

I'm running debian testing and I have encountered a weird bug. Wanted to 
check if that was a real bug or an issue on my end.


The site https://www.w3.org/2010/05/video/mediaevents.html fails on my 
computer with both iceweasel on chromium whereas it succeds on other 
computer (not debian) I have tried it with. The reason is that media 
content downloaded  from media.w3.org over https fail due too :


```
An error occurred during a connection to media.w3.org.

SSL received a record that exceeded the maximum permissible length.

(Error code: ssl_error_rx_record_too_long)
```
Similar error message show up when I try to directly download the 
content from the site using curl. I suspect an issue in the ssl 
implementation but I have not been able to reporduce on other site.


Does anybody have a similar problem?

Thanks
Fabrice

Missing gnutls in PlayonLinux(Wine), but not available to install.

[terryc]

In trying to start battlenet/Wow) under PlayonLine(Wine), the error
messages include missing gnutls.

After searching around, I've come to the conclusion that it can only be
libguntls26:i386, but further searching indicates this is included in
libgnutls-deb0-28:i386.

If that is the case, it isn't being recognised/
Looking for cluebies here.

System is AMD64 running Debian:Jessie with backports
The PlayonLinix is Ver.  4.2.10
The  Wine has been 1.9.7 thru to 1.9.12 staging

I know about the us.blizzard forum thread.
I know about the winehq recommendation and have tried the purge and
re-install.
Weirdly, my system was able to run the game until a battlenet upgrade
about the beginning of the month, when it "broke".

I'm not an NFS expert, but I've been using/sys admin'g NIS/NFS on various 
Sun and Linux systems at home and at work since the late '90s. I have 
never heard of what you're trying to do, but can't categorically say that 
it isn't possible (if the double negative isn't too confusing). I don't 
think the result would be very satisfactory as it seems you'd end up with 
a split home directory with files in both the local and server home 
directories. I think it would be pretty chaotic.


My experience over the years is the NFS automouting is very reliable and 
fairly easy to administer. If your network is stable, then you shouldn't 
have a problem with it at all. If your network isn't stable, then that 
problem should be fixed. I've had software development systems consisting 
of approx. 100 client workstations automouting user home directories from 
a couple of Linux servers (almost always Debian, but some Redhat and SUSE 
- doesn't really matter) with 30 - 40 heavy users. It was very reliable 
and there were almost never any problems.

Is there anything in the Printing section of the wiki which helps you?
It could be a 32-bit/64-bit issue.

Canon Printer Setup

[Levi Darrell]

Hi All,

I'm attempting to use a Canon Image Class MF628Cw from Debian. I downloaded
the drivers from the Canon website at
https://www.usa.canon.com/internet/portal/us/home/support/details/printers/color-laser/mf628cw.
I installed them via dpkg, then added the printer in CUPS via a web browser
at localhost:631.

The printer did not come with a USB cable, and is connected to the LAN.
CUPS sees the printer, and the printer appears as available when I attempt
to print from evince. However, after sending the print signal, the printer
does not print. The "Jobs" page in CUPS says "No jobs," but if I click on
printer and then click "Show All Jobs," I see the following:

Sure, but if your encryption scheme wastes payload in yout packets you
have more overhead for TCP/IP headers in each packet.


Why would encryption increase the payload size ?
Disk encryption with dm-crypt does not (except for the LUKS header).

This is NOT making any sense, common or otherwise.  The copy of 
firefox-esr I copied to the /usr/lib/iceweasel tree day before 
yesterday, then made softlinks to the firefox-esr executables has 
vanished,  yet now I can type iceweasel in a cli, and get firefox-esr, 
v45.2 I think.  And I've no clue where the heck it went.  Not only that, 
but the program (glade-gtk2) that prompted me to do that has also 
vanished, but ISTR it exhibited quite a few signs of bit rot and I 
removed it.  So, at the instant, I have no gui editor that I can use to 
compose working buttons for an addition I am planning to do for 
LinuxCNC.  gladevcp has a slightly better set of buttons than Tkinter 
has, but that means I am stuck editing .xml files with geany, which does 
have a decent xml syntax highlighter.

I feel like I could do more, and faster to a finished gui in tkinter, IF 
I could find some docs on it.  The linkage is pyvcp.

Any clues about that will be gleefully checked out.

Thanks all.

No I haven't Lisi.  The last time I did that, I had to start all over 
again, building me an install I could use.  That was at least a year 
back. It ripped put all the linuxcnc related stuff for starters, I guess 
it thinks email and web browsing is the only thing we do with these 
machines.  Easily fixed by me except for freecad which will not install 
on this final wheezy anymore, but...

I build these machines for ME to use, and if it works and is stable, as 
in still works next week too, well...  It will probably run that way 
until I update with a new install.

If someone tells me I shouldn't do that which I just did to solve a very 
real problem, then along with their finger sharpening, they had better 
be able to explain what is wrong with what I did, in factual terms AND 
how to solve it the _proper_ way.

Thanks Lisi.

That will NOT work when the app complains it can't find iceweasel.  Make 
the directory if its gone, and put the links named iceweasel that point 
at firefox in it.

Humm, not sure where to put it, probably in /etc/aliases, but its 
possible a properly composed alias would also work.  Someone should 
explore that possibility.  Here, it seems to be all user : notheruser 
type stuff.  I don't see such a critter in my home directory though.

Perhaps an export of iceweasel = "firefox", then open a new cli and try 
it. IDK.

OK. So it seems there's another path open() --> EWOULDBLOCK in the kernel.
That would be a chance to read some kernel sources... I fear I must give

Sorry I wasn't clear: I was just talking about the errno -- we still

I wasnt implying that: any of the apps you've caught complaining about
"Resource temporarily unavailable" might do as a help in thinking about
what can be occurring. Can we really say open() returned error and
errno was EWOULDBLOCK after this? (the evidence you've collected seems
to point strongly at this; is there any other possibility?)

Note that this can be a pretty intrusive technique, depending on which

Sure, but if your encryption scheme wastes payload in yout packets you
have more overhead for TCP/IP headers in each packet. I have yet to
actually meet someone who optimizes on that level but at Google scale
these things obviously matter.

It really depends on what you are looking at. Clients have no reason to
care about that but if you are running a busy site that's a whole
different issue.

The first link of yours doesn't really discuss the server-side
implications. The second one is from 2010 and talks about how Google
prefers RC4 for its speed but RC4 is almost completely dead today (see
RfC 7465).  Incidentally, Google switched off RC4 for Gmail just
yesterday:

http://news.softpedia.com/news/google-drops-sslv3-and-rc4-support-in-gmail-504176.shtml

Admittedly, one of the main issues with HTTPS is the number of
handshakes your hardware can do per second. That probably isn't a
problem for the CD image download server that we are discussing here.
But for (non-distributed) sites that serve a huge number of requests
(think tens of thousands of requests per second) and (unlike Google) use

You are right! Firefox starts without errors with the "firefox" as well
as the "exo-open --launch WebBrowser" command even for the first firefox
window.

It is weird though as all eight add-ons were installed in iceweasel for
some months or at least some weeks before firefox was installed in place
of iceweasel. I will now install add-ons on the new profile one-by-one
to see if I can find the guilty one.


Thanks for your help,

On Linux, EWOULDBLOCK is #defined as EAGAIN in asm-generic/errno.h.
Also they are always the same in the glibc, regardless of the operating
system kernel.

You don't have to write your own program, there is already an 'errno'
utility in the moreutils package. :-)

So, the fact that HTTPS doesn't ~actually~ provide you with any security

CPU on both ends,


Sure, but the server is most concerned, a client does not usually handle 
hundreds or thousands of concurrent HTTPS connections.

transmitted somewhat larger.  This is because encrypted blocks have
specific size requirements (...)

Remeber that a single packet can only carry 1460 bytes, before
accounting for services that specify MTUs <1500 .  If you're using
something like 64-byte blocks for the encryption scheme (which is fairly
common, so I'm going with that from here on out), you're limited to only
sending 1408 bytes / packet of actual data, assuming zero overhead.  For
the 660 602 880 bytes of "cd1" from the debian installer suite, this
means you're transmitting 469,178 fully loaded packets, plus 1 partial
(approx 315 bytes) ... or a total transmission of 689 691 975 bytes.


Hmm. I don't know how SSL works, but HTTPS runs on top of TCP so I doubt 
that it cares about IP packet size. The task of splitting the TCP 
payload stream into IP packets is done by the TCP layer.

Vamos a ver... ¿tu servidor de correo Exim 4 qué dominios gestiona?

Porque estás hablando de dos direcciones con dominios distintos
("josealfr...@ucm.hlg.sld.cu" y  "josealfr...@infomed.sld.cu"). De lo
que dices más arriba entiendo que desde la cuenta
"josealfr...@ucm.hlg.sld.cu" puedes enviar correos y recibir sin
problemas y que la dirección que te da error es la de
"josealfr...@infomed.sld.cu", que no te permite enviar hacia
"josealfr...@infomed.sld.cu" y cuando mandas un correo te aparece
registrado el mensaje que enviabas. Bien, pues el mensaje era este:

   josealfr...@ucm.hlg.sld.cu
 SMTP error from remote mail server after RCPT
TO::
 host naix.hlg.sld.cu [201.220.196.178]: 550 No esta autenticado
en el servidor o no pude hacer relay

Lo que yo interpreto, si lo que he escrito arriba es correcto, es que
el servidor de correo que gestiona el dominio "ucm.hlg.sld.cu" no
acepta mensajes del servidor "infomed.sld.cu" pero sí de otros
servidores remotos, lo cual me lleva a pensar que existe algún tipo de
cruce entre los dos dominios (comparten DNS, están en la misma red, lo
gestiona el mismo servidor de correo, o existe algún tipo de enlace o
vínculo entre ellos) porque lo "normal" sería que recharaza todos los
correos no sólo los de un dominio en particular en base al valor
"dc_relay_domains" de Exim.

Entremos al asunto...

sm01@stt008:~$ host infomed.sld.cu
infomed.sld.cu has address 201.220.222.59
infomed.sld.cu mail is handled by 10 mx.sld.cu.
  ^^^

sm01@stt008:~$ host ucm.hlg.sld.cu
ucm.hlg.sld.cu has address 201.220.196.182
ucm.hlg.sld.cu mail is handled by 5 naix.hlg.sld.cu.
ucm.hlg.sld.cu mail is handled by 10 mx.sld.cu.
  

sm01@stt008:~$ host mx.sld.cu
mx.sld.cu has address 201.220.222.97
mx.sld.cu has address 201.220.222.15
mx.sld.cu has address 201.220.222.66

Ahí tienes el meollo: los dos dominios comparten servidor de correo
por lo que estará entrando en conflicto con algún tipo de
configuración interna de Exim que tendrás que tenerlo configurado para
gestionar peticiones multidominio. Así a bote pronto, yo empezaría por
revisar qué contiene la variable "dc_relay_domains".

It isn't unusual with a temperature like that during load, but it
mostly seems to happen when playing demanding games on a laptop.

I wouldn't worry about it if it just happens momentarily, but long
running tasks that stress the system like that is probably not suitable
on a laptop.

Anyway, as others have pointed out, check for dust and make sure that
you don't impede air flow yourself (by placing it on bed for example).

Ordinary saw, and level the wobble out with sandpaper.  Spools these days 
are some sort of foam plastic moldings, might even be cuttable with a 
sharp knife.  Its even possible the glue could wreck the spool by 
dissolving it, one of the reasons I said fabric glue, that may be a 
safer formula than anything full of aromatics.  They are usually bad 
news for foamed plastic.

No.  My only lappy, an ancient HP DV-5120-us, doesn't run that hot. The 
fan kicks in for maybe 10 seconds at 30+ second intervals.  I've used it 
for my "on the road" computer since about 2002.  Email, and a bit of web 
browsing, and acting like a terminal occasionally is about it. OEM 
battery still runs it for a little while but its getting tired too.

That is almost never a solution on a Debian system. 

Try running Firefox with a new profile. This is most likely an
extension you installed is having problems.

Have you tried upgrading again?  There may be some new updates.  And have you 
done full-upgrade?  (dist-upgrade in apt-get)?   To get rid of old stuff that 
will now get in the way.

That's unlikely to hurt anything, but from the package description it
sounds like will only slow a fan down if it doesn't need to run fast,
which isn't your problem.

>From my experience on overheating laptops, the first thing I'd do would
be to clean everything.  Laptops have much more constrained air paths
than desktops, and it's easy for air inlets (this is where I've seen
problems most frequently) or heat sinks to get clogged so you don't get
the flow you need.

Agradeço o esclarecimento com fontes. É bom ver os atores decidindo de perto.

O próprio pessoal da Mozilla tomou essa decisão, pelo que ficou evidenciado.

Like it: :-))

But it requires equipment, like a hacksaw and vice to cut the spools smoothly 
and matching-ly, or your laptop would wobble.  Not all of us have fully 
equipped workshops, Gene. ;-) 

But I love the idea!  Really ingenious.  Have you tried it??

Now that you mention it, Lisi...   When our Blaze (an AKC registered 
Shelty, good house dog, good watch dog) died about 6 years back, he was 
such a part of the family I wanted to get another.  But Dee, my bride of 
26 years now also understood that it was a lot of work she with her 
copd, no longer felt like doing, she took him to the vet, and to be 
shampooed and groomed. I still miss him, and while he was "it was always 
there" fed, if I got out a bowl of anything, I could count on him 
sitting beside my chair in sphinx position because he knew he'd get to 
lick the bowl.  And it took me about a year to quit putting my ice cream 
or cereal bowls on the floor when I was done.  I'd only been doing it 
for a decade.  Old habits...

I would saw a couple of the old, small matching sized thread spools in 
two, cutting so you have a long half and a short half. Put the short 
ones under the front edge, and the long ones under the rear edge, 
possibly securing them beside its existing feet with some fabric glue 
I'd expect you have in the sewing kit.  That would leave far more open 
space for the heat to be carried away than the knitting needles would.
And that sort of glue would allow easy removal in the event you'd have to 
open it and they are hiding an assembly screw.

You don't need to convince me :) -- I just noted that I didn't remember seeing

I see. So still EWOULDBLOCK is the likely "culprit".

I see three things you might try:

  - sift through the kernel sources watching out for a possible
EWOULDBLOCK return on open()

  - have a look at the Emacs sources

  - use the LD_PRELOAD trick [1] to install a little spy on open()
and let the system running for a while like this (the last one
depends on the ratio of how critical your system is and how
corageous you are ;-)

I would concur with JVP, I have my 3 machine tool computers mounted with 
sshfs for file sharing, and do 90% of my gcode work on them with an 
ssh -Y shared key login.  2 of those machines are relatively slow dual 
core atoms that are configured such that normal sw only has access to 
one of their 2 core's, with the other being dedicated to the realtime 
parts of LinuxCNC.  No noticeable lags.  And I don't see lags that could 
be caused by https-anywhere as I browse the net often enough to 
discontinue its use.

Re: Iceweasel substituido por Firefox?

[Sheldon Led]

O que ocorreu na verdade é que, em 2006 a Mozilla não aceitava todas as
mudanças que os desenvolvedores do Debian faziam no Firefox (e outros
aplicativos da Mozilla), daí para aplicar tais mudanças, de acordo com a
DFSG[1] nº 4, eles redistribuiram o Firefox (e outros aplicativos da
Mozilla) sobre outra marca/nome[2].

Ao longo de 10 anos, a Mozilla e o Debian perceberam que todas as
alterações feitas pelos desenvolvedores debian eram aceitas pela Mozilla, e
abriram uma discussão[3] para o Debian voltar a utilizar a marca do Firefox.

Provided they are not in any way obstructing airflow, then assuming they are 
metal ones you WANT them near or under the heat to help conduct it away.  I 
am assuming they are not plastic (shudder - how does anyone manage to knit on 
plastic?), and bamboo is expensive, but you might have saved those pennies 
up   So metal seems reasonably likely.

well, although it may be not convincing to you:
in Tcl it's return from -
'open $fname w'
from man open(3tcl):
'w  Open  the  file  for  writing only.  Truncate it if it exists.  If it
 does not exist, create a new file.'

which is translated to libc open
open (fname, O_CREAT|O_WRONLY|O_TRUNC) (or create())

Back when I had a ThinkPad, I found it would shut itself down at around 
that temperature. I also found that 4500 RPM isn't exactly the highest 
speed the fan can run.


I wrote https://github.com/theothertom/thinkpad-temp_mon to control the

I literally hate when this happens. A thought occurred as fast as that
last email was sent. Low income types like myself don't always have
enough pennies to rub together to even buy a cheap fan of any kind on
demand. Doesn't mean we've completely run out of alternatives. The
dogs busted my first laptop fan's USB connection couple years ago, but
I still used the stand part of it successfully as a coolant aid for
another year or so (until they broke that, too).

ANYTHING that can *safely* get a laptop off the desktop surface helps
even if no extra fan is available in an emergency. Give air every
chance possible to circulate all around the machine.

Mine's currently sitting on top of... knitting needles. They're placed
so that they are not near the hottest parts of the laptop and so that
they do not interfere with any other type of airflow, either. Just
another #Life Lesson Learned the Hard Way due to losing couple
machines over the years k/t the whole low income thing,
yada-yada-grin...

Ditto (same thought process here). I just this week lost a ~3-year-old
*external*, i.e. not even internal, dialup modem to (external) heat in
the house. If you run disks in an internal laptop DVD writer/player,
they'll be so hot they'll almost burn you.

Consider this an emergency situation that needs immediately addressed.
For example, if I personally didn't already have my brain circuits
mentally locked up on fighting setting up home wifi, I'd be searching
the Net for an external laptop fan, the USB kind that sits under the
laptop (oh, and a replacement dialup modem). In the meantime, I
currently have a desktop fan faced toward mine, and it's definitely
helping.

The thing to remember about fans is they don't "cool" like an air
conditioning. They only blow hot air around. Our ongoing job is to
make sure our fans have the easiest time possible shoving hot air
*_out and away from_* our machines.

Just thinking out loud... :)

Como trabalho com a galera da ponta os usuários que apenas usam não estão

OK. I've got one more hint. Reading through the open(2) man page
(assuming it is really open what's failing on you -- what evidence
do you have?), EAGAIN isn't listed among the possible errno values,
but EWOULDBLOCK

   EWOULDBLOCK
  The O_NONBLOCK flag was specified, and an incompatible
  lease was held on the file (see fcntl(2)).

Now, on POSIX systems EWOULDBLOCK and EAGAIN could be one and the
same. Lo and behold, a small test program on my box reveals that
both at least translate to 'Resource temporarily unavailable':

#include 
#include 
#include 

int main(int argc, char *argv[])
{
 printf("EAGAIN is '%s'\n"
"EWOULDBLOCK is '%s'\n",
strerror(EAGAIN),
strerror(EWOULDBLOCK));
}

==>

tomas@rasputin:~/prog/C$ ./errno
EAGAIN is 'Resource temporarily unavailable'
EWOULDBLOCK is 'Resource temporarily unavailable'


This will all depend on things like kernel version, libc and whatnot,
but the most likely candidate at the moment seems to be the app playing
games with fcntl leases.

Seems that the problem is with entire sysvol share. 
I used psexec -s -i cmd.exe to run cmd.exe as SYSTEM user in Windows
computers.
Windows 10 can access \\domain\sysvol and \\dc\sysvol just fine.
Windows XP (cannot try in Windows Vista currently) cannot access 
\\domain\sysvol nor \\dc\sysvol (but they can access other normal
shares). Also, user logged in to system can access shares normaly. Only
system has the issue.

When XP accesses sysvol, then samba log is (end of it):

It happens to any file on any ext4 partition which are locally mounted.

Is there a way to find out at least which part of the system is responsible

Re: ThinkPad fan

[Hans]

Hi, 

the rotation of the fan does not mean, it is cooling! I believe, there is a 
lot of dust in the exit for the warm air. So, I suggest, to open your notebook 
and make sure, that the air is good flooding.

The temperature for Intel cpus (as far as I know), should be about 40-60 
degrees, whilst those from AMD are at the same clock speed a little bit 
higher, so about 60-80 degrees Celsius.
 
These are no absolutely temeperatures, just a mark. 90-100 degrees is much too 
high.

Also check, what is controlling the fan: BIOS or some software.

Good luck, 

Hans

systemd and plymouth not caching LUKS passwords

[Ramon Diaz-Uriarte]

Dear All,

It is my understanding that both systemd per se from v227 and plymouth
will cache passwords[1]. However, there is no caching of LUKS passwords in
my setting, a laptop with two encrypted partitions, corresponding to root
and swap, and where both share the passphrase.

I am using systemd 230-2 and plymouth 0.9.2-3+b1 and running kernel
linux-image-4.6.0-1-amd64 (kernel 4.5 behaves the same way). Trying with or
without plymouth makes no difference (i.e., I am always asked for both
passwords).

I wonder if there is something I need to set/unset, or if I need to create
some (which?) script in /etc/systemd/system. 

My /etc/crypttab is

crypt-sda5  UUID=   noneluks
crypt-sda2  UUID=   noneluks


And my /etc/fstab is

proc/proc   procdefaults0   0
UUID= /boot   ext3defaults  
  0   2
/dev/mapper/crypt-sda5 / ext4 errors=remount-ro,user_xattr 0 1
/dev/mapper/crypt-sda2  noneswapsw  
0   0


Best,

é ... não era bem isso. A mozilla tinha uma política de marcas que
proibia distribuir binários modificados (exemplo backports de correções

Yeah, it's not much in the way for the hardware ... but it's still
electricity and bandwidth that needs paying for.

Not that I'm opposed to 'secure' transmissions by any means -- I'm more
personally opposed to "it MUST be HTTPS or else it's no good" thinking
that has started cropping up more and more recently.

"Install 1" may be using something like gnome keyring manager with a

Absolutely.  95C is pushing the thermal thresholds of CPU dies (IIRC,
100C is the burnout temp on most).  Clean your heatsink too.

Hi,

I recently installed Jessie on a Lenovo ThinkPad T420. The fan usage looks
reasonable. However, high temperatures (96 C) are reached when CPUs are
running intensively for more than one minute or so. The fan speed at those
temperatures is about 4500 rpm.

Do you think it is ok, or do you suggest to force lower temperatures, e.g.,
with thinkfan [1]?

Et si j’essaie avec Firfox-ESR 45.2, ce problème n'apparaît pas.

If the problem is somehow repeatable, you might try to run your
program under strace to actually pinpoint the system call setting
EAGAIN (perhaps you've already done that, but I couldn't imply
that from your post).

Other things to check: does that happen on any files? On a
specific file system? If yes: how is that one mounted?

The computer is a kind of server.
It is writing every second to about 100 files, every 8 hours creating new
files and closing old ones.
It has been running 7/24 for years without stopping.
All files are on its local disk (in three partitions).
It all worked fairly well on Debian 7 (linux kernel 3.20-4-amd64) for quite
long time until I moved it to Debian 8 a few weeks ago.


Thank you Sven, but I'd rather like to get some advice how I could trace and
pin down the problem.

For the present I have not even got a clue where it could be.
Is it in the kernel or systemd or elsewhere ?

following -
http://0pointer.de/blog/projects/resources.html
(Is it perhaps outdated ?)

I've put DefaultControllers= in /etc/systemd/system.conf
for my desktop and reboot it.
I couldn't see any difference in journal
 there isn't DefaultControllers
in 'man systemd-system.conf' )
Surely it was a blind shoot - I don't like such alike.
But what can I do ?
There is nothing in logs concerning the error and it's not easy to reproduce.


Thanks,
  Andrey

Ass: Configurar HP Deskjet 3630

[danielal...@mailcat.cat]

Enviat des del meu mòbil LGGràcies. Per camins semblants als que dius, he anat 
a parar a la versió 3.16.5 i s'ha instalat sense cap problema, tant al PC fixe 
amb Debian 8.0 Jessie com al portàtil de la mitja taronja amb Debian 7.3 
Wheezy. A la xarxa wi-fi i tot! I podem imprimir els dos.

This statement has to be corrected: the overhead of https is hardly perceptible
on "modern" hardware. (See, e.g.,
https://www.keycdn.com/blog/https-performance-overhead/ ,
https://www.imperialviolet.org/2010/06/25/overclocking-ssl.html )

cron, sshfs and sudo

[Wim Bertels]

Hallo,

use case: use cron to mount a sshfs share (with automatic key auth)

on 1 installation this is working fine:
script:
"
#!/bin/bash

sudo -u user1 sshfs user1@123.234.1.2:/var/user1/shared /mnt/shared

exit
"

on the other it keeps failing because the passphrase needs to be entered
to unlock the key, it doesn't fail however without sudo and a custom
user1 crontab entry; but as cron is run by root, this should be able to
do easier

suggestions?

mvg,
Wim

Re: boot times out after dist-upgrade on Stretch

[Borden Rhodes]

First, a huge shout out to /usr/share/doc/systemd/README.Debian.gz for
telling me that appending systemd.debug-shell to the linux line in
grub would let me run a shell even whilst the main boot couldn't drop
into an emergency shell. I think this should be writ in large friendly
letters at the start of any boot-related troubleshooting guide from
now on.

With that, I could dump journalctl and systemctl list-jobs to files.
In perusing these files, it confirms that boot chokes at 4
dev-disk-by\x2duuid-<...>.device, dev-mapper-sda5_crypt.device &
dev-mapper-LVG\x2d.device, but curiously not
dev-mapper-LVG\x2droot. root, of course, has a fstab pass value of 1
whereas the others have a pass value of 2. Is this a clue? The
list-jobs dumps also show some 94 other units waiting in line to run.

A little search-fu later, it seems I may have caught this bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=758808. However,
other searches on other distros suggest everything from hdparm needing
to be removed (didn't work), to incorrect fstab entries (did you guys
see any error in them?), to lunar cycles, to a butterfly flapping its
wings etc.

Anyhow, notwithstanding any better ideas, I think I'm going to
redirect this conversation to bug 758808.
