[buildd-tools-devel] Bug#633671: schroot behaves differently depending on cwd

[Thibaut VARENE]

Package: schroot
Version: 1.4.19-1+squeeze1
Severity: normal

While debugging the old 'create-chroot.sh' script from pkern that was having hickups, I finally realized that schroot behaves
apparently inconsistently depending on the cwd:

This works:
buildd at envy:~$ schroot -c sid-ia64-sbuild -u root -- apt-get update
Hit http://debian.ens-cachan.fr sid InRelease
[...]

This doesn't work:
buildd at envy:~/chroots$ schroot -c sid-ia64-sbuild -u root -- apt-get update
E: Failed to change to directory '/home/buildd/chroots': No such file or directory

>From what I can tell, trying to run schroot from any directory /below/ the home directory fails with the above error.
Running from "higher" directories (such as /, or /tmp) works.

I've traced both schroot invocations with -v, there is absolutely no difference (save of course for the session UUID) in the outputs.
