[buildd-tools-devel] Bug#584961: schroot: lvm-snapshot device lock permission failure

[Zach Carter]

Package: schroot
Version: 1.2.3
Severity: normal

When a non-root user is accessing an lvm snapshot chroot, the call to lockdev 
is made with insufficient permissions, resulting in this error:

E: test-f13-401b1c48-570f-48bb-8389-4b6d44f18577: Failed to lock chroot: 
/dev/fastvg/f13lv: Failed to lock device: Failed to lock device

This issue can also be reproduced in schroot 1.4.2

Additional details are available in Fedora bug 600638 here:

The patch proposed there consists of moving the setuid call to an earlier 
point before the call to lockdev is made.
