That's actually not easy to do portably. See Sys-Filesystem.
Then you have to figure out what those options mean on each OS.
And the mount options won't tell you whether your NFS volume is
backed by something sensible like UFS or ext4, or whether the admin has
done something crazy like export a FAT filesystem or re-export something
from Samba. This is important if you want to know things like whether
hard links are supported, or whether it is case-sensitive vs
case-preserving vs case-smashing.
