modifying debian installer image

[Fourhundred Thecat]

I have downloaded debian netinstaller:

wget
http://ftp.debian.org/debian/dists/stretch/main/installer-amd64/current/images/netboot/debian-installer/amd64/initrd.gz

I have unpacked the image, and I was looking around to try to understand
how it works. I assumed, there was some config file with a list of all
the packages that are going to be installed.

I would like to modify that list, and replace systemd with sysvinit-core.

I don't see any such package list in the installer, and I could not find
much information on how the installer works.

Could somebody please help me understand, where the installer gets the
list of packages it installs ? And how I can change that list?

PS: I know I can remove systemd and install sysvinit-core *after* the
installation. But I am trying to avoid installing systemd and then
removing it. I would like to install sysvinit-core right away.

I am also using preseeding for installation, but as far as I know, this
cannot be achieved with preseeding alone.

thanks,

Thanks for the link. I think the whole NFS stuff is a really ugly and 
partly broken dinosaur. I'm using NFS (v3) for decades now, and all the 
glitches are still not really solved. And CIFS for Linux clients seems to 
be no way to go.

I'm afraid I have to setup Kerberos to work-around the broken ipmapd 
stuff. More than a little bit "oversized"...

Thanks for the help!

The "some guy" who does that will also modify the ~/.profile file or
similar startup scripts to _ensure_ that their program is in the
beginning of the PATH, no matter what the PATH variable was originally.

If $USER has a malicious program running with their $UID the program can
do everything the $USER can do. It's a game over situation and default
settings in ~/.profile or similar do not matter.

But sometimes it may be useful to write a root-owner startup script (one
example: /etc/X11/Xsession.d/50custom-stuff) which could do something
like

rm --force "$HOME/bin"
cp --recursive --force /etc/skel/. "$HOME"

so that some default files are restored at every login.

I unmuted it from within alsamixer menu: F6 and went into the USB card table.

If not, is it perhaps muted?

You can use to unmute

alsamixer -c 2

-c 2 is for the second card not to mix up with arecord -c1 which is telling

a user without administrator privilege can generally put "malware"
anywhere in *his own* home directory and it could possibly cause the same
damage from there (if the system is configured properly hopefully not
that much), so this does not matter, I think.

I think you forget that your "some guy" must be either the user him- or
herself or the system administrator (root)! If your users or
sysadmins desperately want to shoot themselves in the foot, don't worry,
they will find some way, you will not be able to stop them. But why would
normal people do such a thing? And any malware programmer who secretly
"injects" something bad into your system will probably not rely on ~/bin
being at the start of PATH, these people have other ways.

Why? If the user puts a program called "evilmalware" there, it simply
does not matter where in PATH it is. And when the user does something
sane instead, as in my "poedit" example, it will no longer work :(

I think the reason is exactly as I and others have said, the benefit to
security you get by omitting ~/bin from the beginning of PATH is more
"feeling" than "reality", the real dangers are waiting somewhere else :)
And the benefit of this default setting is that a user without privilege
may override a system default command.

Thinks to reply (very fast :D)

I think it's may dangerous because generally system command should be
highter older then user's command.

For example , some guy put a "rm" but named "ls" to ~/bin . This "ls"
can be virus or ransomware , user may not know it's not which he
want("ls").

So I think put ~/bin to tail of $PATH has better security for normal user.

For me, I will avoid use same name with exist command, and for user
who want use same name , I believe he know or will learn how to modify
$PATH.


I mean , put ~/bin in tail of $PATH will batter for default setting,
so does developer has another reason to put to beginning ?

It always amazes me that people think that something that didn't cost 
them any additional money is necessarily free. We live in a society 
chock full of nefarious operators (commercial, governmental, and 
free-lance). There can be a lot of issues with just accepting a 
manufacturer's software. I've seen the support disc for a printer 
install a half-dozen or more services (and set them to run automatically 
at system start) without any notification whatsoever to the user.


I'd also say that the Open Source drivers available for many devices do 
not differ significantly in usable functionality (as opposed to lacking 
special "features" from the proprietary ones. Furthermore, many users 
don't even need all of the regular functionality provided by the 
proprietary drivers. How many of us have multi-function printing devices 
at home which include fax capability? How many of us actually use that 
fax capability at home? If you don't need it, why install additional 
software to support it?


Some of the proprietary driver packages I've seen appear to be a 
hodge-podge of Open Source / Freeware / Proprietary software collected 
by support groups that are barely holding on by their fingernails. How 
often is that stuff perused for security or functional issues? They're 
barely getting it out of the door to keep up with the plethora of new 
printer models! It can be a bit horrifying to watch a truly ugly 
installation process grinding away for minutes doing whatever it wants 
under the root account -- often without signifying just what it's doing 
to ownership and permissions or what it may be altering in config files 
or just what it's dumping in system folders.


I'm pretty sure that the vendors don't always know just what they're 
providing in their driver packages. Whoever wrote the installation notes 
for some of the commercial printer drivers I've played with recently 
definitely didn't know how to install those drivers -- on any OS.


I'd rather use drivers from the official repos. The people who put those 
packages together know the OS and its desktop environments, ostensibly 
are following the policies of the distro, are communicating with members 
of other teams pertinent to use of the driver, and are presenting their 
packages for an assessment process by testing and unstable users and 
release teams. Me likey.


A proprietary driver has to at least appear to be well made, provide 
reasonable documentation, and offer me something very special to make my 
risk / benefit analysis go its way. And, no matter how great the 
proprietary driver is, I won't use it if the only real difference 
between it and the Open Source driver is that it supports something I 
don't use.


Just some thoughts on what some of the people who amaze you may be thinking.

like other people already pointed out there shouldn't be anything
dangerous about this.
One possible use case is for example that you could put there a
minimal script that temporarily overrides some environment variable, like
one I have here which reads:

#!/bin/bash
GTK_IM_MODULE=gtk /usr/bin/poedit $@
exit $?

This way I can conveniently call "poedit " with the desired
setting of GTK_IM_MODULE without either having to type the whole thing
each time or else having to permanently change GTK_IM_MODULE's setting
(the default value of which I modified for other reasons).

It's strange, isn't it, that some people do not want to knuckle under
and do what they are told is best for them. The same people want some

A Brother with all of:

   GhostScript)

will not need a driver.

Very interesting, thanks. Is this documented / explained anywhere? I
think I understand why 1 and 3 might be relevant to the need for
drivers, but 2?

FWIW, my HL-2280DW meets 1 and 2, but not (apparently) 3, and indeed
does seem to require a driver.

I do not see why 1 and 2 are in any way necessary to use a printer
without a proprietary driver. PostScript or PCL6 emulation is, however,
a pre-condition. The HL-2280DW has PCL6 emulation.

Very interesting, thanks. I (re)dipped my toes into the mysteries of
printer setup, and (eventually) configured another version of my
HL-2280 using CUPS settings of "Generic / Generic PCL Laser Printer".
The CUPS test page printed out correctly, although I see that many
options exposed by the Brother proprietary drivers do not seem to be
exposed by the generic one, which makes sense, I suppose. I do like
those options, though (e.g., duplexing and "toner save" / quality
options).

I'll have to do more testing to see whether the core printing
funnctionality, at least, is on par with the proprietary driver's.

Thanks again,

It always amazes me that people who get a driver made specifically for a 
device, a driver that has significantly more capability than one that 
came with their Linux os,
would refuse to use it. It hasn't cost them anything, just as the Linux 
os hasn't cost them anything, so it is FREE. (Don't tell me they paid 
for it with the printer--they
couldn't have bought the printer without subsidizing the driver, so 
essentially it is free.)  Same goes for video drivers. It's like trying 
to swim with one hand tied behind your back.

A short howto I wrote years ago

1) find out cards and inputs

shell> cat /proc/asound/cards
 0 [Intel  ]: HDA-Intel - HDA Intel
  HDA Intel at 0xff95 irq 22
 1 [HVR900 ]: USB-Audio - WinTV HVR-900
  WinTV HVR-900 at usb-:00:1a.7-3, high speed
 2 [Webcam ]: USB-Audio - Philips SPC 1000NC Webcam
  Philips CE Philips SPC 1000NC Webcam at
usb-:00:1a.7-5.4, high speed

=> I'm going to use the Webcam built in mic => card # 2

2) find out the input

shell> cat /proc/asound/devices
  0: [ 0]   : control
  1:: sequencer
  6: [ 0- 2]: hardware dependent
  7: [ 0- 3]: hardware dependent
 16: [ 0- 0]: digital audio playback
 17: [ 0- 1]: digital audio playback
 19: [ 0- 3]: digital audio playback
 24: [ 0- 0]: digital audio capture
 32: [ 1]   : control
 33:: timer
 56: [ 1- 0]: digital audio capture
 64: [ 2]   : control
 88: [ 2- 0]: digital audio capture

=> my input is the capture on the second card

 88: [ 2- 0]: digital audio capture

3) so no we can test the mic

shell> arecord -c1 -Dplughw:2,0 -f cd -vv /dev/null

Should probably be supported by this:

https://manpages.debian.org/stretch/libsane-common/sane-pixma.5.en.html#FILES

You'll need to put the IP in /etc/sane.d/pixma.conf as described in that 
section, eg. bjnp://

For my MG3250 it sometimes gives an error trying to connect the first time, but 
it wakes the scanner parts and it works the second time.

This seems to work (I used "0", since the existing line had "0"),
except for the fact that each time I print a page (via the CUPS "Print
Test Page" feature), it prints out twice. Why? [I commented out, and
then actually removed, the original cupsFilter line, restarting CUPS
each time.]

Ah, I guess this is what a reported trying in my other email. As you
suggest, it works, but important features seem to be missing.

Very interesting, thanks. I (re)dipped my toes into the mysteries of
printer setup, and (eventually) configured another version of my
HL-2280 using CUPS settings of "Generic / Generic PCL Laser Printer".
The CUPS test page printed out correctly, although I see that many

Assuming dmesg is producing any output (some systems may require

Apologies. I missed off a ";" when translating the changelog entry to
be used in your 99mono file. Also Progress-Fancy turns out to be not
what you want.

"-o Apt::Color=0" works for me not to see the orange colour in stable
and unstable. In a file it works on stable but not on unstable. There
seems to be a bug here.

Your explanation is just what I was looking for...  Very simple and clear.

Yes, as far as I understand this is probably the main problem: find something
that works with Linux...

Hmm. I'm not so sure

On my local workstation, my ID is 3000. On the Synology, the id is 1027. 
On both machines, my user name is "jd". SO, if the mapping is "name 
based", I should see all the files with uid 1027 on the servers with the 
correct name on the client.

This is not the case! A "ls -l" shows me all the different UIDs, but 
neither the corresponding name, nor "nobody".

I try cp/chmod/chgrp again tomorrow morning and post the result here.

Thanks so far...

They're just boxes which can have more than two mics (or line-level
signals
eg from instruments) plugged into them.  Inside there's multiple
analogue-
to-digital converters.  The digital data from all of these is then sent
along 
the USB connection to the computer.  Some interfaces might send all the 
channels so they arrive in a single file on the computer, which then
contains
multiple separate channels, others may directly generate separate files
on 
the computer.

It's unimportant which you get because a file containing multiple
channels
can be split into separate files (with eg sox), or a set of files can be
combined
(with eg sox).


I can't advise you on what to buy...  because I suspect you're going to

more recent 
version of that these days...   A box like that is aimed at people used
to using 
professional audio equipment.  

There will be lower-spec interfaces around too, but you obviously need
to find 
one that's known to work with linux.  You also probably don't want one
with

Yes, more or less.



Try "mount -v -t nfs name.or.ip.of.synology:/ /some/mountpoint" and see

Mounting isn't the problem. The mount is working without errors

   mount.nfs: trying text-based options
   'hard,intr,vers=4,addr=192.168.1.1,clientaddr=192.168.1.88'

My only problem is the (very old) goal to get different uid/gid working.


OK, that's good. NFSv4 doesn't send UIDs/GIDs over the wire any more, it 
sends Usernames and Groups. So, if "fred" on your client is UID 1001, 
but 'fred' on the server is UID 1005, then the file will get saved with 
UID 1005. On reading it back, you should get the reverse mapping - 
there's a file belonging to UID 1005, on the server that's "fred" so 
"fred" is sent over the wire and the client sees that as it's own 
version of "fred".


The problem comes when "bill" tries to access the share. "bill" doesn't 
have an account on the server, so he will get mapped to "nobody". This 
probably gives bill read access, but not write access and, certainly, if 
bill CAN write files, they won't end up belonging to them.


So, ideally, you need to find a way to synchronise the user lists. You 
can either manage /etc/passwd (and similar on the Synology) manually, or 
you can look at some sort of Active Directory system whereby clients are 
registered with a central server and perform their name lookups against 
that.

Or find gnome-session (or gnome-shell - I don't recall who exactly
spawns user applications in GNOME) process pid, execute something like
this on login:

gdb -p $(pidof gnome-session) -ex 'p umask(0077)' --batch

You'll need gdb to be installed, of course.

(Responding late because of vacation.) Starting with Stretch, mouse
acceleration is controlled by libinput.  It was mentioned in the Release
Notes BTW.  Here is a clear explanation of its possibilities:
https://wiki.archlinux.org/index.php/Libinput
See 'man libinput' for the available options.

In short, you create the file /etc/X11/xorg.conf.d/10-libinput.conf,
containing something like this:

Section "InputClass"
  Identifier "mouse"
  Driver "libinput"
  Option "AccelProfile" "flat"
  Option "AccelSpeed" "-0.5"
EndSection

Mouse acceleration is set with 'Option "AccelSpeed"'.
Its value ranges from -1 to 1. Negative means slower.

Try "mount -v -t nfs name.or.ip.of.synology:/ /some/mountpoint" and see

"/" from the server. NFSv4 *may* use a 'chroot'-style layout where all 
the exported directories appear under a virtual root, or it *may* use 
the NFSv3-style layout where you need to know the location of each 
export.


Does the Synology offer NFSv3 and V2 as well? Is the NFSv4 that the 
Synology offers "kerberized"? 

If the Synology offers NFSv3, you can try "showmount -e 
name.or.ip.of.synology" to see what's exported (as I understand it, 
showmount no longer works with NFSv4).




The second try was the ugly solution using CIFS. The bad insight this

is no ID mapping too. My hope with CIFS was, that die total user and

It might if I didn't have so many different installations scattered about and
multiple aliases to create. Better to suffer horri-colors until an Apt config
that works can be found.

In openSUSE we have Zypper as wrapper around rpm more or less the way apt works
with dpkg. Color on/off in Zypper is easy to deal with because of integrated
comments that work so much better than virtually empty config directories, e.g.:

...
## Whether to use colors
##
## Valid values: always, never, or autodetect
## Default value: autodetect
##
 useColors = never
...

djbwares version 6

[Jonathan de Boyne Pollard]

djbwares is now at version 6.

* http://jdebp.eu./Softwares/djbwares/
* http://jdebp.info./Softwares/djbwares/

The main changes here are in dnscache and ftpd.

dnscache now has a built-in  resource record for localhost, like it 
already had a built-in A resource record.  I've slightly improved the 
way that it caches  resource record sets, to match the way that it 
was handling A resource record sets.  And it now caches SOA resource 
records.  There are also some minor improvements to the logging to 
decode SRV, A, and  records rather than print them in raw 
hexadecimal format.


The changes to ftpd were motivated by my pointing several WWW browsers 
at a publicfile FTP site and discovering that the WWW browsers adhere to 
the RFCs far less than they used to at the turn of the century.  You can 
read some of the saddening discoveries in the Hall of Shame.  I have 
enhanced publicfile ftpd to support OPTS, FEAT, SIZE, EPSV, and HOST; to 
interoperate better with some faulty FTP ALGs that cannot cope with an 
FTP server that one does not need to log in to; to interoperate better 
with some faulty WWW browsers that misuse CWD as a type testing 
mechanism; and to log things more clearly in order to diagnose such 
faults from server logs.  HOST support means that ftpd supports virtual 
hosting on FTP, which is explained in the manual, although it is hard to 
find any FTP client that employs this.


* http://jdebp.eu./FGA/web-browser-ftp-hall-of-shame.html
* http://jdebp.info./FGA/web-browser-ftp-hall-of-shame.html

A further minor addition is a host command, a subset of the host 
commands from ISC and from KnotDNS that uses the same DNS client library 
from djbdns as all of the other djbdns query tools do.  Of course, the 
conventional djbdns client tools have a simpler syntax and more regular 
behaviours than the host command, and are preferable.  Moreover, the 
subset excludes rarities that djbdns has never supported, such as non-IN 
class queries.

Thanks...

$ cat /etc/debian_version
buster/sid

$ uname -a
Linux lenovo 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2 (2017-06-12) x86_64 GNU/Linux

`dmesg | grep -i cm108 -A 10 -B 10' produced no output at all...
