Subject: dmsquash-live/iso-scan: Provide an easy reference to iso-scan device.
X-Git-Tag: 051~46
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=12ab0dce66f07f54304d690cc07a5a72396e2939;p=thirdparty%2Fdracut.git

dmsquash-live/iso-scan: Provide an easy reference to iso-scan device.

With commit 3c8c807, /run/initramfs/isoscan and /run/initramfs/live
mountpoints are unmounted upon rd.live.ram boots.  Save a link to
the iso-scan device in /run/initramfs/isoscandev to easily remount
the source, if desired.
