Is this really something that would be desirable?
It seems to me that if you think checking for bad blocks is needed it
would be worth the effort of booting from a mini distrobution on CD or
floppy and run the check from there.
I don't see any option in the fsck man page for doing a bad block check.
Unless you want to hack on init scripts (checkfs.sh and checkroot.sh)
to use the filesystem specific stuff directly with the options you
want I don't see a way.
I see that the badblocks man page has a big fat warning:
Normally, badblocks will refuse to do a read/write or a
non-destructive test on a device which is mounted, since either can
cause the system to potentially crash and/or damage the filesystem even
if it is mounted read-only. This can be overridden using the -f
flag, but should almost never be used --- if you think you're smarter
than the badblocks program, you almost certainly aren't. The only
time when this option might be safe to use is if the /etc/mtab file
is incorrect, and the device really isn't mounted.
