Personally, I have several mountpoints in my home directory
with meaningful names: ~/cdrom is for CDs, ~/flash is for
my USB memory stick, and ~/cf is for my compact flash card
adapter. I also have a ~/floppy mountpoint, but I haven't
used it for ages. :-)
I haven't added those mounts to /etc/fstab, because I don't
think they belong there. Those entries would rather belong
in a file like ~/.fstab or ~/.mountrc, but mount(8) doesn't
My solution was to write a small shell function "mount"
which is a wrapper for mount(8). Now I can simply type
"mount flash", and it mounts the flash stick and -- if
successful -- cd's into ~/flash. Another wrapper function
"umount" (no argument required) cd's out of the current
mount and then umounts it. Quite convenient.
PS: Just to sum up, there are three conditions that _must_
be fulfilled for user mounts to work:
1. sysctl vfs.usermount=1
2. The user must OWN the mountpoint.
3. The user must have READ+WRITE access to the device
being mounted (e.g. by chgrp'ing it to a special group,
or use the existing operator group, and then chmod g+rw).
The user doesn't have to (and shouldn't) own the device,
though. Also, making the device world-writable is pro-
bably a bad idea, so use a group.
Maybe those three points should be mentioned clearly in the
