[CentOS] Centos6 Migration glitch - ZFS-FUSE

Folks

My experiments with installing ZFS-FUSE in a Centos 6 system reveal 
behavior different from that observed in Centos 5.6.

The version of ZFS-FUSE is that provided on the EPEL repository, and 
was installed on a 32-bit machine.  I use it because of its 
deduplication facility.

In Centos 5.6, the facility worked as advertised.

In Centos 6, however, the system "hung" in initialization upon the 
first reboot after installing ZFS-FUSE and creating a pool.  By 
"hung", I mean that the cute sliding blue bar that progresses during 
bootstrap got to nearly complete and then stood there for at least 20 
minutes.  The identical computer, configured without ZFS-FUSE, 
completed the system initialization within normal time.

Following some clues found by googling the bug, I suspected that 
AUDITD and ZFS-FUSE had a conflict.  After several experiments, I 
found what appears to work.

REMEDY:

When you install ZFS-FUSE, it will start the zfs-fuse service, and 
will also automatically issue a "chkconfig zfs-fuse on" command.  The 
remedy is to prevent zfs-fuse from running during initializtion by issuing
   chkconfig zfs-fuse off
and starting the service after the initialization is complete.

I personally chose to start it via a crontab entry as root:
   @reboot <something>
where "something" could be the direct service call, or (as was in my 
case) the starting of a script to do a bunch of startup things 
including starting zfs-fuse service.


IS THIS THE DESIRED BEHAVIOR
I sort of doubt it, and I'm sure it will eventually be sorted out by 
the zfs-fuse developers.
