filesystem mounting

Hi all,

I have a question regarding filesystem mounting.

I have one Sun box(V240) and a NAS on a network. Sun machine shows the following output of df -k command.
# df -k

And the vfstab is like this

#cat /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options

You will find the entries of the filesystems from NAS box is commented in vfstab. Then also it is mounting that all filesystems whenever I reboot the Sunbox.

How that commented entries are going in /etc/mnttab?

Thanks in anticipation...

Perhaps the kind person who set up automounter added in commented entries to vfstab to let you see what they had done.

I concur! Always leave a bread trail when doing changes like this--I'm sure that is all these comments are
