Bug#824963: systemd-fsck run fsck for same disk in parallel

[Yuriy M. Kaminskiy]

Package: systemd
Version: 215-17+deb8u4
Severity: wishlist
Tags: jessie patch fixed-upstream

Dear Maintainer,

When mounting several filesystems, systemd runs all fsck in parallel. 
This is very unoptimal when filesystems shares same (rotational) 
physical disk.
systemd-fsck had provision to run fsck with -l option, but it was
temporarily disabled due to locking conflict between fsck and udev.
This conflict was fixed in util-linux-2.25, and "fsck -l" option 
re-enabled in systemd-217.
As jessie already has fixed version of util-linux (2.25.2), please 
consider cherry-pick commit v216-652-g48d3e8d (and maybe bump Depends on 
util-linux to 2.25 to reflect this) for next jessie point release.
(Debdiff attached).
