Re: [gentoo-user] Fwd: Set mount point of external drive with udev rules

[mikey]

I don't blame people for not wanting to touch this with a barge pole,
it's a complete nightmare. I have had success to a degree in that I
created a .fdi file which gives my device a pseudo label of music so
it now gets mounted as /media/music and I found a -rather basic -
script to mount devices via HAL and DBUS
(http://www.datapax.com.au/apps/halmount/), so if I run my script on
boot then my drive starts up mounted as a unique location. This is
however a hack.

I have still been unable to make any kind of match using UDEV rules on
my system and would like to know how or where I'm going wrong.
