No.  Although the shutdown sometimes hangs, it is quite reliable
nowadays.  Just do a normal sysvinit shutdown (e.g. use halt, or
shutdown).

That being said, there are two issues that fsck will constantly
complain about:

/dev/hd0s1: Deleted inode 95849 has zero dtime.  FIXED.

This is somewhat benign, but they accumulate until there is no free
inode left.  Then ext2fs crashes.  Affects only the root filesystem.
Solution: fsck every now and then.  Proper solution: kill almost all
processes, then umount the root filesystem.  We will be able to do
this with the bootshell.

/dev/hd0s1: i_file_acl_hi for inode 81872 (/proc) is 32, shoud be 0.

This is actually a bug in fsck, fixed upstream.
