I have added a new option -p to the mount command. This was

Browse Source 
inspired by SunOS version of mount which uses option -p to
indicate that the mount information should be printed in fstab
format.
This is a neat way to create a new fstab file to use later when
one has modified the mount points or mount options or added or
removed mount some mount points. You just type

	mount -p > /etc/fstab.new

and there is your new fstab file ready to be used though you
will of course have to add any necessary noauto flags manually.

[Committers note:  This also seems to do the wrong thing for AMD
 mounts, but in the more average case this is a nifty feature nonetheless
 and one can always edit the bogus entries out]
