Re: forced fsck (again?)

[Eric Sandeen <sandeen redhat com>]

Some hints for xfs, which does not enforce check intervals, so:

- no mechanism or need to delay next check
- no mechanism to enforce check on next boot; just notify w/ email
- no mechanism to read last-checked; just check on acceptable cron 
  interval

Also, you really want to use xfs_repair -n instead of xfs_check; 
it's much faster and more memory-efficient.

So most of the xfs) cases are just documenting that xfs can't 
and/or doesn't need to do anything, they don't really need to 
be there - up to you. :)
