Subject: [PATCH] rootfs-block/module-setup.sh: add support for xfs / reiserfs
|
||
|
|
separate journal device
|
||
|
|
|
||
|
|
xfs and reiserfs (among other) supports storing journal data to a
|
||
|
|
separate device. Unfortunately, XFS requires this information to boot
|
||
|
|
properly (reiserfs can embed the information in its metadata but you
|
||
|
|
might want to override it).
