Subject: move all /dev/.initramfs to /dev/.run/initramfs
X-Git-Tag: 009~74
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b177e9133e52e17726c771991d45f72c7142ded6;p=platform%2Fupstream%2Fdracut.git

move all /dev/.initramfs to /dev/.run/initramfs

We want all "/var/run" information to live in /dev/.run, until the real
root is mounted.
Therefore we mount a tmpfs on /dev/.run, which can/will be bind/move mounted
on /var/run later on.
