OK, so it's the 50chrootname script failing here.  The only change
to that script in the last year has been the addition of a single
line:

  d04e32dd etc/setup.d/50chrootname       (Roger Leigh 2012-04-03 23:29:40 +0100 24) . "$SETUP_DATA_DIR/common-config"

  http://anonscm.debian.org/gitweb/?p=buildd-tools/schroot.git;a=commitdiff;h=d04e32dd3cc39ea641fc2848957292fe94751925

However, as you can see by looking at the diff, that line was added
to all the other scripts as well, and you should have the script here:

  % ls /usr/share/schroot/setup 
  common-config  common-data  common-functions

Since you get the "Setting chroot name..." message, the only other line
in the file which can fail is:

  echo "${CHROOT_NAME}" > "${CHROOT_PATH}/etc/debian_chroot"

Which would imply that this failed.  It doesn't give an error why--did
your debug log also capture stderr?  If not, a copy with stderr included
would be useful here.  All the variables like CHROOT_NAME and
CHROOT_PATH look correct.  SETUP_DATA_DIR is likewise correct for
sourcing the shell scripts at the top.  Is /etc/debian_chroot writable
by the setup script?  / and /etc must be writable by root.

So it would be very useful to know
- the stderr (e.g. run with script or 2>&1)
- if you can check the filesystem permissions or anything else that
  might interfere with writing (e.g. free blocks/inodes)


I'm not sure the grave severity is justified here.  From what you've
shown, this can only be a single line in the 50chrootname setup script
failing.  All the values set in the script are correct AFAICT, so it's
most likely down to a filesystem issue or some other problem making
that single echo statement fail.


Thanks,
Roger
