And as I explained, the standard sucks. /mnt on the distro I use
contains the following directories:

cdrecorder
cdrom
dvd
floppy
hd
memory
tmp
zip                 

and it puts the following text in /mnt/README

The purpose of the /mnt directory is to provide a place for the admin to
mount block device temporarily.  Any of the subdirectories of /mnt may be
used, or volumes may even be mounted directly on /mnt (which is the
traditional way of doing things, though /mnt/tmp is also provided for
the purpose of mounting any kind of volume temporarily).

See the /media directory also.

IOW: it leaves the choice to the user. What Philippe does is exactly
the same: let the user choose whether he want to use the non
standard sotlution that does not suck and that use to be a standard
practice in Linux world, or the standard solution that sucks.

I thought we agreed this was a sensible solution.
