Description Michal Jaegermann 2012-01-18 20:04:22 UTC 
Description of problem:

/usr/lib/dracut/modules.d/98usrmount/mount-usr.sh has the following line:

echo "$_dev $NEWROOT/$_mp $_fs ${_opts},ro $_rest"

which adds "ro" to mount options for /usr if that lives on a separate file system.  So far so good but nothing seems to even try to remount that file system later leaving it "read-only".  Unfortunately that does not agree so well with a "normal" system use.  Say, updates are not likely be happy.

Is that a really good reason to have that ",ro" above?  AFAICT fsck happens before /usr is mounted and dracut what that ",ro" skipped produces initrd which results in "normal" mountings.
