Why don't usb flash devices auto mount?
« on: June 09, 2009, 07:33:04 AM »
Just curious as to why when plugging in a USB flash device it is recognized as a "device" and added to  /mnt but it is not mounted. What would I have to change to get this to happen automatically?

Also, I have noticed a super trivial carriage return is required after plugging a USB device in to get terminal  control back.

Because that would be rude, and for many would not be wanted. Think the autorun on Windows systems.

To get it to happen automatically, you could add "mount -a" to the end of rebuildfstab

Thanks. Sometimes I just can't help myself and will be rude. I assume this will auto mount all devices "plugged in" to any device port. Let's say I wanted to limit this behavior to just USB devices. I don't want to auto mount CDs.

If your drives are fat32, "mount -a -t vfat" only mounts those.

If you wish to restrict things better, just parse /etc/fstab or the directories in /mnt for desired devices.

I just tried this and it didn't mount sdb1 after I plugged the device in.

The device is present and I can manually mount and unmount it.

I'm using microcore 2.0 with core extensions.

Ah, indeed :P I forgot noauto is added in the options list.

This message is a bit too cryptic for me. Are we giving up?

No, you can just remove "noauto" from the options list in rebuildfstab :)

No giving up allowed =o)

"noauto" is a mount option for the device added to fstab.  This makes the device need to be mounted explicitly, so mount -a won't mount it.


EDIT: ignore the following.  I misread curaga's reply and his solution is much better.

Personally I'd go for a check of the specific device rather than have to manually edit fstab every time:

Code: [Select]
for i in sda1 sdb1 sdb2 blah blah blah whatever; do
if grep "/dev/$i" /etc/fstab; then mount /dev/$i; fi
done
...or something like that

puppy had this brilliant mount utility called mut (or maybe mutt). You clicked on the icon and it showed all your drives. You could then click on a button next to each one to mount or unmount. Another option was a link to open them in a file manager (Rox was the one I had at the time).

We have a mount tool too ;)
It shows one drive at a time, you can click through all the drives and mount/umount.

I know - and it is one of the better ones I've seen. But Mut(t) is better looking!

I'm not familiar with Puppy (tried it once a while back, didn't care for it, don't remember why) so I can't say anything about "better looking", but I really like tc's mount tool - simple and functional, elegant even.

It would be cool if there were a variant with the buttons side-by-side instead of over-under, and smaller, so it would swallow without gagging the tray (in jwm) - though the way it is now is much better for unswallowed use.  Gentler colors wouldn't hurt.

My vote would be for a submenu in tools that would support changing some of the system variables like "enable/ disable"  automount.
