For the record: I tried to move everything to udev and after some testing it works.
Udev rules for sd* automounting without /etc/fstab: KERNEL=="sd[a-z]", NAME="%k", SYMLINK+="usbhd%m", GROUP="users", OPTIONS="last_rule" ACTION=="add", KERNEL=="sd[a-z][0-9]", SYMLINK+="usbhdp%n", GROUP="users", NAME="%k" ACTION=="add", KERNEL=="sd[a-z][0-9]", RUN+="/bin/mkdir -p /media/usbhdp%n" ACTION=="add", KERNEL=="sd[a-z][0-9]", RUN+="/bin/ln -s /media/usbhdp%n /mnt/usbhdp%n" ACTION=="add", KERNEL=="sd[a-z][0-9]", PROGRAM=="/sbin/vol_id -t %N", RESULT=="vfat", RUN+="/bin/mount -t vfat -o rw,noauto,sync,dirsync,noexec,nodev,noatime,dmask=000,fmask=111 /dev/%k /media/usbhdp%n", OPTIONS="last_rule" ACTION=="add", KERNEL=="sd[a-z][0-9]", RUN+="/bin/mount -t auto -o rw,noauto,sync,dirsync,noexec,nodev,noatime /dev/%k /media/usbhdp%n", OPTIONS="last_rule" ACTION=="remove", KERNEL=="sd[a-z][0-9]", RUN+="/bin/umount -l /media/usbhdp%n" ACTION=="remove", KERNEL=="sd[a-z][0-9]", RUN+="/bin/rm -f /mnt/usbhdp%n" ACTION=="remove", KERNEL=="sd[a-z][0-9]", RUN+="/bin/rmdir /media/usbhdp%n", OPTIONS="last_rule" I have tested them with my external hd connected via IDE to USB connector. It's 80 GB with two 30 GB vfat partitions + 20 GB reiserfs. The rules will create (and destroy on removal): 1. /dev/usbhd0 (the sda device) available to all users 2. /dev/usbhdp1-3 (one per partition: sda1, sda2, sda3) also available for all users 3. mount points for all /dev/usbhdp1-3 devices in /media/usbhdp1-3 4. symlinks from /mnt/usbhdp1-3 to /media/usbhdp1-3 so they will be available in both /mnt and /media No /etc/fstab items are needed. There are two rules one for vfat partitions with fmask (rw for everybody) and dmask (rwx for everybody) and second for the rest of filesystems. I had a lot of problems with detecting vfat partitions from udev but finally it worked. Pmount is not very helpfull because I couldn't setup umask to 000 when it was run as root from udev. Using pmount could save a few rules but I would have to create a special user and run it through sudo. I have also found this usb automounting script package: http://usbmount.alioth.debian.org/ which is a more configurable and pretty version of the above. For cdrom (/dev/hdc) I couldn't do much using only udev. AFAIK there are no hotplug events available to udev that can be used to detect cd insertion or eject. But I wanted to get rid of submount and then I found a tiny application auto-eject-cdrom: http://psydev.sourceforge.net/new/auto-eject-cdrom/auto-eject-cdrom-0.2/ I've followed this advice: http://www.ubuntuforums.org/showthread.php?t=52548&page=3&pp=10 and made a quick pkgbuild: pkgname=auto-eject-cdrom pkgver=0.2 pkgrel=1 pkgdesc="Ejects cdrom and mounts/umounts it when you press eject button/insert new cd" url="http://psydev.sourceforge.net/new/auto-eject-cdrom"; depends=('eject') source=(http://psydev.sourceforge.net/new/$pkgname/$pkgname-$pkgver/$pkgname.c \ http://psydev.sourceforge.net/new/$pkgname/$pkgname-$pkgver/Makefile) md5sums=('2db638621d1db9e67953acd026060274' '9fcc4e65448455d8a0201dc180fb44fd') build() { cd $startdir/src sed -i "76s#umount#eject#" ./$pkgname.c make || return 1 install -D -m755 $pkgname $startdir/pkg/usr/bin/$pkgname } umount is replaced with eject and then it works: umounts and ejects when eject button is pressed or closes and mounts it when you insert a new cd and press eject. You can run it from /etc/rc.local for example: auto-eject-cdrom /dev/hdc & In /etc/fstab I only left this for /dev/hdc: /dev/hdc /mnt/cd auto ro,users,noauto,unhide,iocharset=iso8859-2 0 0 and in my custom udev rules I've put: BUS=="ide", KERNEL=="hdc", SYSFS{removable}=="1", PROGRAM="/bin/cat /proc/ide/%k/media", RESULT=="cdrom*", NAME="%k", GROUP="users", SYMLINK+="cdrom cd cdrw dvd dvdrw", OPTIONS="last_rule" so all users have access to /dev/hdc. Everything seems to work so far :-) -- Rafal Szczepaniak (Lanrat) _______________________________________________ arch mailing list [email protected] http://www.archlinux.org/mailman/listinfo/arch
