Strange issue with autofs5/fc6

[Michael <michael@kmaclub.com>]

I am seeing some weird behavior with autofs/mount. 

/proc/mounts, mounts, and auto.master don't seem to agree.

/proc/mounts:
filer:/export/users/mythtv /home/mythtv nfs 
rw,vers=3,rsize=262144,wsize=262144,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=filer 
0 0

mount:
filer:/export/users/mythtv on /home/mythtv type nfs (rw,addr=192.168.101.1)

Here is my auto.master
ypcat -k auto.master
/home auto.home 
bg,hard,intr,retry=10000,rsize=8192,wsize=8192,acregmin=3,acregmax=60,acdirmin=30,acdirmax=60,timeo=600,retrans=5,nfsvers=3,tcp

The 262144 size is strange and I don't have any idea where that is 
coming from.

Also, mounting by hand:

[root@client ~]# mount -o rsize=8192,wsize=8192 
filer:/export/users/mythtv /mnt
[root@client ~]# mount | grep mnt
filer:/export/users/mythtv on /mnt type nfs 
(rw,rsize=8192,wsize=8192,addr=192.168.101.1)
[root@client ~]# grep mnt /proc/mounts
filer:/export/users/mythtv /mnt nfs 
rw,vers=3,rsize=262144,wsize=262144,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=filer 
0 0

Any thoughts on what is happening here?  Is rsize really 262144 or are 
things being reported incorrectly?
