Package: partman-zfs
Version: 5
Severity: important
mount.d/zfs sets ZFS filesystems up for automated mount. Automated mount
is very dangerous because it leads to collision when two ZFS-based operating
systems are installed in the same pool.
If ZFS is used for /, it will be overlaid on top of the real /, making /dev
useless (and rendering system unbootable on both sides).
If ZFS is used for other subdirectories, a mix of both operating systems
will be used. Results are unpredictable.
As a workaround, zfsutils doesn't automatically mount/unmount filesystems
that have been marked for automated mount. See changelog entry for 8.2-3:
http://packages.debian.org/changelogs/pool/main/z/zfsutils/zfsutils_8.2-3/changelog
Attached patch switches partman-zfs to legacy mount. However, it can't be
currently used because of bug #637082.
