Re: What filesystem for no-halt boot?

I know that the XFS by design does not need to fsck before mount since
all fsck operations are always performed at mount time.  Therefore I
believe it is completely non-interactive.  I personally have not had
any failures or interactive blocks when using it.  But my experience
is limited.  But the man page for xfs should make you feel good.

  apt-get install xfsprogs
  man fsck.xfs

DESCRIPTION
       fsck.xfs is called by the generic Linux fsck(8) program at
       startup to check and repair an XFS filesystem.  XFS  is  a
       journaling  filesystem  and  performs recovery at mount(8)
       time if necessary, so fsck.xfs simply exits  with  a  zero
       exit status.

ReiserFS does have fsck functionality.  But I think the behavior is
the same.

  apt-get install reiserfsprogs
  man resiserfsck

       -a, -p These options are usually passed by fsck -A  during
              the  automatic  checking  of /etc/fstab partitions.
              erfsck  to  print  information  about the specified
              file system.  No checks are performed.  When it  is
              set  - reiserfsck assumes that it is called by fsck
              -A, provides some information about  the  specified
              filesystem and exits.
              For compatibility, these options simply cause reis

That value would be set in this file and not on the lilo command line.

  editor /etc/default/rcS

  # Set FSCKFIX to "yes" if you want to add "-y" to the fsck at startup.
  FSCKFIX=no

If the time it takes to fsck is not a factor and it sounds like it is
not then any of the journaling filesystems should be fine.
