[Pkg-iscsi-maintainers] multipath not automounting iscsi devices listed in fstab

[Christian Seiler]

Control: reassign -1 multipath-tools
Control: found -1 0.5.0-5

Dear multipath-tools Maintainers,

this is bug, which is a clone of #775778, is essentially the same
problem as was discussed in #775778: the ordering of the
multipath-tools init script after after $remote_fs (see Should-Start
line in LSB headers) causes an ordering problem, because systemd will
wait for all _netdev filesystems in /etc/fstab before the equivalent
of $remote_fs is reached.

This means that systemd will wait for the /dev/mapper/... devices
related to multipath to appear during boot, but at a point where
remote-fs.target (systemd's mapping of $remote_fs) is not yet reached.
This will lead to a 90s timeout (systemd's default timeout when
waiting for devices), only then will systemd continue booting.

Please see the original bug report for details w.r.t. open-iscsi; the
same reasoning applies to multipath-tools.

The same fix that was implemented for open-iscsi in principle also
applies for multipath-tools, i.e. make sure that for systemd systems
the unit is ordered before remote-fs-pre.target. I don't use
multipath-tools myself, but I'll be able to prepare a patch that fixes
this on a minimal level tomorrow, you'll just have to test it
yourself.
