Subject: [PATCH] dmsquash-live: add /dev/mapper/live-base
|
||
|
|
|
||
|
|
This is similar to the reason for adding the
|
||
|
|
/run/initramfs/live-baseloop symlink -- access to the original live
|
||
|
|
image without overlays.
|
||
|
|
|
||
|
|
livemedia-creator does not create a osmin.img, so there is no mountable
|
||
|
|
device for it to use when rsyncing the live image to the target. It
|
||
|
|
needs a device that points to the original live image without overlays.
|
||
|
|
|
||
|
|
Note that lmc won't be creating osmin.img, since really isn't needed any
|
||
|
|
longer. Its purpose was to provide a minimal image that could be dd'd to
|
||
|
|
the target. Now that we use rsync this is no longer necessary.
|
||
|
|
|
||
|
|
The included patch adds a /dev/mapper/live-base device that Anaconda can
|
||
|
|
use whether or not there is an osmin present.
