Someone should enhance mkinitrd to have an --update
option. It has a limited form of this with the
--tabonly option. This, however, only updates the
initrd's copy of /etc/clustertab. A true --update
option would also copy in any new network drivers in
/etc/modules.conf, and maybe do the proper update to
/linuxrc if chard is enabled/disabled for the root. The
might be some other things --update could do, too.
Unlike --tabonly, the --update option could require the
kernel version number as an argument (which is also
needed for building an initrd from scratch). For
example, it would need this to copy in new network modules.
Considering that the kernel version may be required,
there's some question in my mind how valuable this
feature over just building an initrd from scratch.
That's why the priority is low.
