I'm not really a fan of automount, but I understand that lots of
people are. I'm trying to get it fully functional under mdev, and then
do a write-up on the wiki page. A Google search turns up lots of
examples of code. However, the examples are for embedded devices, and
they assume the only user is root. I've got the automounting and
autounmounting working. Everybody can read the mounted USB stick, but
only root can write. I've tried pmount with the umask option, but it
doesn't help. Assume the scrpt gets passed MDEV="sdb1"
#
# Create the directory in /media
mkdir -p /media/${MDEV}
#
# Change permissions to allow read+write by all
chmod 777 /media/${MDEV}
#
# Mount the directory in /media
pmount --noatime --umask 000 /dev/${MDEV}
But after the mount...
user2@aa1 /media $ ll
total 3
drwxr-xr-x 3 root root 1024 May 22 19:02 .
drwxr-xr-x 19 root root 1024 May 21 20:41 ..
drwxr-xr-x 5 root root 1024 May 16 01:42 sdb1
Every directory and file belongs to user:group root:root. On the USB
stick all directories are 755 and files are 744. As a heavy-handed ugly
hack, I could...
chgrp -R users /media/${MDEV}
chmod -R g+w /media/${MDEV}
to a USB stick. I obviously don't wnt to do that on the external USB
drive that I rsync my system to every few weeks. Any ideas? And oh
yes, I do realize I'm trying to re-invent the wheel. The old one has
a broken udev :(
