Enable mounting of NFS file systems.
The umount command will also free that loopback device.
You can still use the 'losetup' utility (to manually associate files
- with loop devices) if you need to do something advanced, such as
+ with loop devices) if you need to do something advanced, such as
specify an offset or cryptographic options to the loopback device.
(If you don't want umount to free the loop device, use "umount -D".)

++ from one handheld to another). So, maybe we actually want a few
++ more fields here, (depends, suggests, etc.), so that that would
++ be guaranteed to work even in the absence of more information
++ from the available file.
++
++ 28-MAR-03: kergoth and I discussed this yesterday. We think
++ the essential info needs to be here for all installed packages
++ because they may not appear in the Packages files on various
++ feeds. Furthermore, one should be able to install from URL or
++ local storage without requiring a Packages file from any feed.

-+ Enhances, perhaps we could generalize all of these and save some
