I have a default 12.1 slack installed. When I want a usb flash drive
mounted I su- and give the command:

#mount -t vfat /dev/sda1 /mnt/key

I detect if the flash drive (key) is actually mounted by the df command.
Unmounting is:

#umount /mnt/key

I made the mount point, /mnt/key, myself.

I've recently discovered that If I just plug in the key, I will get a gui
labeled '4.1 Removable Media-KDE Daemon' on my kde window that will prompt
me for what to do with this key I just plugged in. It asks if I want to:

1. Open a new window
2. Download photos with digikam
3. Do Nothing

If I select number 1, it opens Konqueror and shows me the tree for the key,
so it has mounted the USB flash drive for me. There is a 'configure' button
that gives me a new gui ...Configure-KDE Control Module.... with all kinds
of options. I don't use it, and I don't know if this is slack/kde alone, or
if digikam is part of it, but it does show that slack/kde are capable of
mounting a USB media without cli commands. I'm sure it can also be done
automatically if configured to do so. Maybe someone else can take it from
here.

I've only read about a long way. It uses "udev", "hald" and "d-bus".

Maybe "usbmount" helps:

http://usbmount.alioth.debian.org/

(it's unmaintained since more than 1 year).

"Ubuntu" - an African word, meaning "Slackware is too hard for me".

Have a look at /usr/doc/udev-/*

On a Slackware 12.1 system the file
/usr/doc/udev-118/docs/writing_udev_rules/index.html
will probably cover everything you want/need to know.

Thank you. I am reading. One think the document don't cover: How do
I know a device's KERNEL/SUBSYSTEM/DRIVER name before write a rule?
Can I get it from sysfs?

Thanks.
