You can do this by "mkdev fd"

You can increase the number of inodes by modifying line 399 of
/usr/lib/mkdev/fd.  It says:

	mkfilesys ${swplo}:640 || {

You need to increase the 640 value to something
larger (This is the number of inodes that will be created on
the floppy).  Considering that the default frequently doesn't work,
the difficulty of finding this is ridiculous.

If you have made an "Unscheduled" backup, or a level 0 scheduled backup,
then you can use cpio to restore the system.  The directions on
page 65 in "Tips, Tricks and Troubleshooting" in the User's Guide
have worked for me before to successfully restore a crashed
ODT system.

To do this, you *should* do as suggested above and rebuild the
root partition if it has crashed.  All of this is a real pain
in the ass and poorly documented.

Now if I could just figure out why custom(ADM) keeps giving me
and error 10, (10, not 11) I'd be all set.

		Good luck,
