Package: sbuild
Version: 0.57.3-1
Severity: normal
In using sbuild with the latest version of schroot, lvm-snapshot type
chroots uninstall the dependencies that they installed, rather than
allowing them to be removed by the LVM snapshot being destroyed.
The cause seems to be that the function sbuild::chroot::session_flags in
schroot-1.2.0/sbuild/sbuild-chroot-source.cc is concluding that it should
set the flags to CHROOT_SESSION_PURGE instead of CHROOT_SESSION_CLONE; but
sbuild is checking for whether it is Session Cloned, not Session Purged.
The documentation in the schroot code in sbuild::chroot::session_flags
suggest that sbuild is checking the wrong field ('Session Cloned' rather
than 'Session Purged') here, but I'm not entirely certain.
Below is the relevant schroot --info output.
