Hello!

   I've noticed a strange interdependency between FS mount options (RELENG_6
as of 20-Aug). I'm using "rw,sync" options in my /etc/fstab for the root
partition. W/o NFS export of it, 'mount' output looks good:

/dev/ad0s4a on / (ufs, local, synchronous)

However, when I export this partition with "-alldirs -ro" options, mount
stops to show "synchronous":

/dev/ad0s4a on / (ufs, NFS exported, local)

Is it just a bug in 'mount' output, or is "synchronous" option indeed silently 
removed during the NFS export of FS?

Sincerely, Dmitry
