Subject: sbuild: LVM snapshot -source chroot not correctly managed

Date: Mon, 23 Jul 2007 17:42:34 +0200

Package: sbuild
Version: 0.56
Severity: normal

  Hi,

  I use a LVM snapshop to build my package. To update (and after
upgrade) chroot, I would like to be able to type:
/usr/share/sbuild/updatechroot sid-source

I've the following config :
* /etc/schroot/schroot.conf
[sid]
type=lvm-snapshot
location=/sid
groups=sbuild,root
root-groups=sbuild
source-root-groups=sbuild
device=/dev/atsina/sbuilder
lvm-snapshot-options=--size 2G
[...]

* /proc/mounts
[...]
/dev/mapper/atsina-sbuilder /srv/sbuilder ext3 rw,data=ordered 0 0

* ls -l /src/sbuilder
total 24
drwxr-xr-x 22 root root  4096 2007-05-09 16:04 etch
drwx------  2 root root 16384 2007-07-10 09:29 lost+found
drwxr-xr-x 22 root root  4096 2007-07-17 13:02 sid

  You can note that the 'location' parameter in schroot.conf refer (as
stated by the documentation) to the RELATIVE path inside the LVM
filesystem.
"schroot -c sid bash" gives me a bash shell in a snapshot
"schroot -c sid-source bash" gives me a bash shell in the original
filesystem.


  In /usr/share/perl5/Sbuild/Chroot.pm, in function "_setup_options",
you have the test:
        if (defined($chroots{$distribution}) &&
	            -d $chroots{"$distribution"}->{'Location'}) {
Of course, "/sid" does not exists on my system. So the command
"/usr/share/sbuild/updatechroot sid-source" fails with the error message
"sid-source chroot does not exist" and leave me with bind-mounted
directores that I've to manually unmount :
$ mount
/dev/mapper/atsina-sbuilder on /var/lib/schroot/mount/sid-source type ext3 (rw,sync,user_xattr)
proc on /var/lib/schroot/mount/sid-source/sid/proc type proc (rw)
/dev/pts on /var/lib/schroot/mount/sid-source/sid/dev/pts type none (rw,bind)
tmpfs on /var/lib/schroot/mount/sid-source/sid/dev/shm type tmpfs (rw)
/home on /var/lib/schroot/mount/sid-source/sid/home type none (rw,bind)
/tmp on /var/lib/schroot/mount/sid-source/sid/tmp type none (rw,bind)


  To work-around this problem, I tried to add this symlink:
"/sid -> /srv/sbuilder/sid" on my root filesystem.
It works.

  I also tried to modify the test in Chroot.pm.
In this case, it fails later with:
Error in tempfile() using /sid//var/lib/sbuild/apt.conf.XXXXXX: Parent
directory (/sid//var/lib/sbuild/) is not a directory at
/usr/share/perl5/Sbuild/Chroot.pm line 145
  So $chroots{"$distribution"}->{'Location'} seems to be used at several
places.

  Best regards,
    Vincent

Thanks for reporting this.  I think we probably want the "Path" rather
than the "Location", as reported by "schroot -i".  However, I will
need to double check that before making any changes.

Just to confirm that: if you run

  % schroot -c sid bash

what is the output of

  % schroot -i --all-sessions
  % schroot --config --all-sessions

? (run this from another shell prompt).

Roger

Hi,

Sorry for the delay in replying to this bug.  testing migrations
and time prevented a new sbuild upload until a few weeks ago.
sbuild 0.57.0-1 or later should fix this bug.

Please could you confirm if this fixes the bug for you?


Thanks,
Roger

I will not have the time this week: I need to keep a working sbuild
and will not have time to correct the situation if there is still a bug.
  I will try next week. Do not hesitate to ping me if I forget.

Hi, did you have a chance to check this was fixed yet?

Subject: sbuild: LVM snapshot -source chroot not correctly managed

Date: Tue, 10 Mar 2009 13:29:19 +0100

Package: sbuild
Version: 0.58.0-1
Followup-For: Bug #434396

  Hi,

  With 0.58.0-1, symlinks in / are not needed anymore.
However, for -source chroot, "schroot --info" (or "schroot --location")
does NOT indicate the location of the chroot.

  The small patch below "fixes" the problem for me but this is a hack.
The good solution is probably either manage -source chroot specificaly
in schroot or clone this bug report to schroot to make it display
the location.

Subject: Impossible to run sbuild-update with LVM-based chroots

Date: Mon, 30 Aug 2010 12:18:56 +0200

Package: sbuild
Version: 0.60.0-2
Severity: normal

Hi,

I cannot make sbuild-update work with -source with my LVM snapshot schroots.

I have the following snippet in /etc/schroot/schroot.conf:

[sid]
type=lvm-snapshot
description=Debian sid snapshot
users=didier
groups=adm
root-groups=sudo
source-root-users=root,didier
aliases=unstable,default,unstable-amd64-sbuild,experimental-amd64-sbuild
lvm-snapshot-options=--size 10G
device=/dev/Icterus/schroot-sid-amd64
mount-options=-o noatime

And I can't run:

$ sbuild-update sid-source
Chroot for distribution sid-source, architecture amd64 not found

I don't understand what I am supposed to do to get this work.

TIA, OdyX

If you're using schroot >= 1.4.8 in unstable, you'll need an
updated sbuild to work with source chroots;

http://git.debian.org/?p=buildd-tools/sbuild.git;a=commitdiff;h=3426a619aa9069bb88be72ea1c454acd9467c879

Hopefully, we'll get this updated version uploaded to unstable soon.

Roger

With sbuild 0.60.3 (just uploaded to unstable), sbuild should properly
understand source chroots [schroot >= 1.4.8 have namespaces, including
a 'source' namespace].  The various sbuild-* helpers now default to
using the source chroot for chroots which provide a source chroot.

Could you let me know if this fixes things for you?


Thanks,
Roger

I just upgraded my sbuild machine (from 0.59.0-1 to 0.60.3-1)
I had to comment deprecated config options (run-exec-scripts, ...)
to avoid too many output but all seems to work.

There is just one change which I do not known if this is a bug or a
feature: before the upgrade, I was running
"sbuild-update unstable-amd64-source". Now, I must run
"sbuild-update unstable-amd64" to update the *source* chroot.
  Is it the intended behavior (I will then fix my scripts) or is
it a bug (in this case, I will open a new bug report) ?

"schroot -c unstable-amd64-source" and "schroot -c unstable-amd64"
do the correct (expected) thing.

Yes, this is intended.  It will automatically select the source chroot
for you.  Note that in new schroot releases, the chroot is actually
named "chroot:unstable-amd64" and the source chroot
"source:unstable-amd64".  The "-source" suffix is still avilable (as
an alias) for compatibility, but sbuild uses the new names.  Basically,
it's just prefixing the names with the appropriate namespace for you,
and for the sbuild-* commands, it defaults to using the source
namespace.  You do, however, have the option of using the complete
namespace-qualified name to use a specific chroot.

You should find that
"schroot -c source:unstable-amd64" and "schroot -c chroot:unstable-amd64"
are directly equivalent.  The -source suffix will be dropped post-squeeze
once all the tools are updated to use namespaces.  Note that the
namespaces are mostly optional--schroot will by default search in the
appropriate namespace for the action you want to perform.

Roger

  Thanks for all these infos. Note that schroot.conf(5) still talk about
the -source suffix and not about the namespaces.

Thanks, I'll make sure that documentation is updated, and also update the
sbuild docs.  I'll keep the bug open just for now to remind me to do this.

The schroot documentation is now updated, so I'll close the bug now.
