That's a really good point. The remount is always necessary if fstab
specifies / with non-default options, and I think some file systems
will not enable certain options on remount if already mounted rw,
hence the initial ro mount in order to read the fstab in the first
Anyway, the work around is to use kernel parameter rootflags= to
specify the mount options and then comment out the / entry in fstab.
