ah different ballgame...  you can now shoot me for my prev posts :-)

and you can turn off fscking by removing the fsck'ing line in the bootup
scripts, tht it wont do any checks .. makes it faster and dangerous too

ahh but ... ext3 is still extremely bad for "appliances" with no
kb/screen/mouse

there is no clear answer, but ext3 is not it since it depends on ext2A ..
	- xfs, jfs, reiserfs, jjfs, jjfs2 ( not ready for primetime )
	- even fat-16 might be an option if you can handle the
	8.3 file name restrictions

the full scan would depend on how badly its corrypted and will try
to fix it ... after too many inode propblems, it(fsck) says "here you fix
it and confirm that it should be fixed based on what i6t thinks it should
be"
