util-linux: Add mount lock patch
Add the mount lock patch that moves the lock file from the potentially R/O /etc, to the R/W /var/lock directory. This resolves a problem when mounting when / (and /etc) is mounted R/O. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>

The FHS indicates that /etc must be capable of being mounted R/O.
|
||||
|
||||
The FHS also indicates that lock files belong in /var/lock, and /var must
|
||||
be R/W as soon as possible during boot.
|
||||
|
||||
This patch moves the mtab lock file from the potentially R/O /etc, to the
|
||||
R/W /var/lock area. This lock file is used when mounting disks and making
|
||||
other mount adjustments. The _PATH_MOUNTED_TMP is not adjusted, as failing
|
||||
to write to this file does not cause any functional limitations.
|
||||
|
||||
(Note, if /etc is R/O, then /etc/mtab should be a symlink to /proc/mounts)
