[buildd-tools-devel] Bug#691694: schroot: /var/lib/schroot/ cannot be a symlink

[Jakub Wilk]

Package: schroot
Version: 1.6.4-1
Usertags: serious

An (unintended, I hope) consequence of symlinks mount point 
canonicalisation is that /var/lib/schroot cannot be a symlink anymore. 
In my setup, /var/lib/chroot was a symlink to /srv/chroots/meta. This 
made schroot mount devices in very wrong places:

$ chroot -v
