Subject: schroot: Invokes PAM common session modules in host

Date: Sat, 26 Apr 2008 17:38:44 -0400 (EDT)

Package: schroot
Version: 1.1.6-1
Severity: normal

schroot invokes PAM in the host machine before entering into the chroot. 
This results in the host machine's session modules getting run, which is 
causing problems for me with PAM session modules that are not idempotent 
(in particular, I was problems with this causing a new OpenAFS PAG to be 
created when entering a build chroot so that the build didn't have the 
credentials to copy the new .deb out of the chroot, until I changed 
/etc/pam.d/schroot to only run the pam_unix.so session module).

While it makes sense to me that schroot might want to use PAM for auth, 
account, etc. modules, I'm not aware of situations when schroot would 
benefit from running the common-session modules on the host machine -- it 
seems like perhaps schroot should only run the pam_unix session module. 
But not knowing that the schroot PAM support is used for, I can't really 
be sure.
