Ok,
There is a way, recently i saw something in the fuse configuration.
"./configure --disable-mtab"
Now with this option if you build fuse based filesystems will not update
/etc/mtab.
So i think there is nothing that glusterfs needs to provide as such,
unless fuse gives
enhanced API for fuse_mount to request for ignoring mtab.
Regards
