Default Auto mount of removables

Is there any new method around for automounting
removables? I have beeen using supermount since
Slackware 8.2 (before that in Mandrake), it works
just nice, but it has some issues..

Mountpoints are static and does not get created
on the basis of the hw or volume in question.

One has to hunt around for new, hopefully working
kenel patches for every new kernel version, and of
course patch and compile the kernel..

On the plus side is that supermount works smoothly, plug
in a mem-stick, a CD or whatever, and it is there in the
mountpoint, eject and put in a new CD.. it is there.
Easy config once in place, one simple line in the
ordinary fstab, nothing else.

I am not asking for that dbus/hal/udev/hotplug mess.
I am asking around if anybody have seen/read/heard of
any new method of solving automount/umount and creating
mountpoints on the basis of the HW or volume in question,
a solution that is fairly simple and does not depend on
thousand of other things.

you could try autofs.
look at these links for explanation/howto

No, i feel that is messy compared to supermount.
I also understand that autofs does not umount
as needed when you change media or plug-out/in.

Maybee i am close to the answer in my description
of one of the issues. Now i am thinking of a script
that creates the mountpoint and adjust the apropriate
supermount-fstab-line. But how does one get the kernel
to run a script with the right arguments? or the other
way around, have a script listen to kernel... syslog??

Hmmm...

No, not really.

" udev - Linux configurable dynamic device naming support "

This is not what i am looking for, and leads to
the messy path of udev/hotplug/hal/dbus/portmap.

I just want to automaticly crate a mountpoint named
after the HW-type (mass-storage/CD/DVD/Floppy .. )
or its volume name if present, then adjust the mountpoint
in fstab and let supermount do the rest.

But i do not know if this really is possible, i think i
have to ask this question to some supermount maintainers..

yeah, AFAIK udev won't work without it, right?

yes, really. you want the kernel to run a script when a specific device is
plugged in. udev provides this functionality. from 'man udev':

PROGRAM
Call external program. This key is valid if the program
returns successful. The environment vari* ables of udev are
also available for the program. The string returned by the
program may be additionally matched with the RESULT key.

perhaps hotplug alone can do it, at least the description in the man page
would suggest so. i just never did anything with hotplug other than install
it, so i can't tell for sure.

I have just discovered a solution i never have seen before:
Submount:
http://submount.sourceforge.net/

It is semes to be quite like supermount and uses fstab in
similar way, but this is a module that does not require a
kernel compile and has also a program called submountd.

But Submount does not name the mountpoints, just like
supermount. Is there anybody here in this NG with
experience from Submount?

OK, missed that when i RTFM..
I will look more closely on it, thanks.

Maybee that can be used.

With usb-removables hotplug can do it.
I am using it today to chmod and chgrp access
to my scanner and PTP-protocol digital camera.
It could just as well do some md and filewriting.
But CD/DVD...??? Maybee..

But i still think hotplug is messy, a slow
loading deamon that i rather live without.
But maybee it can be speeded up, skip some
parts of it that i do not use anyway.
