Hi,
I have finally made some effort on writing flexible yet very simple automounter
for FreeBSD desktop.
Feel free to submit me BUG reports ;)
It currently supports these file formats:
-- NTFS(rw) requires [port]sysutils/fusefs-ntfs[/port]
-- FAT/FAT32
-- exFAT requires [port]sysutils/fusefs-exfat[/port]
-- EXT2
-- EXT3
-- EXT4 requires [port]sysutils/fusefs-ext4fuse[/port]
-- UFS (DOH!)
It keeps state of the mounted devices at /var/run/automount.state and logs all
activities to /var/log/automount.log file.
The place for the script is at /usr/local/sbin/automount.sh executable.
The only additional configuration it requires are those lines at the end of
/etc/devd.conf file along with restarting /etc/rc.d/devd daemon.
notify 200 {
match "system" "DEVFS";
match "type" "CREATE";
match "cdev" "(da|mmcsd)[0-9]+";
action "/usr/local/sbin/automount.sh $cdev attach";
};
notify 200 {
match "system" "DEVFS";
match "type" "DESTROY";
match "cdev" "(da|mmcsd)[0-9]+";
action "/usr/local/sbin/automount.sh $cdev detach";
};
The /usr/local/sbin/automount.sh executable is here:

I have made tests with 3 different USB drives, with different and same
failesystems, connecting them all at once, disconnecting all at once, random
connect, disconnect etc.
Currently it seems to work ok but suggestions are very welcome.
> Some things to consider/test:
>
> How do I set custom flags, like nosuid,noatime,nodev,noexec,async (or
> sync) for mounts?
Currently You can add these options to filesystem specific mount command, but
its definitely possible.
> What if make a usb drive with an illegal name, existing name or other
dangerous values?
The filesystem label is not used at all, I just use device names, which are
reported by FreeBSD, so quite bulletproof here and then create appreciate
/mnt/da0s1 directories.
> Can I use the automounter to either mount over another mount to
> impersonate it, or can I overwrite arbitrary files or directories?
I have done everything to check that and to omit that, if not, then submit a BUG
;)
Thanks for suggestions Matt.

Hi, I removed the state_lock and stat_unlock mechanisms as they appeared to be not needed, I have shufled with 3 drives all the time and the 'integrity' has not been lost, at it was a lot faster, because the lock always had to wait for the 'slowest' drive (in term of initializing the device, like USB hard drive). I simplified the 'attach' section a lot, now each filesystem contains only check/fsck (if possible), mount and log info. I also simplified and improved the 'detach' section a little. I have added an option to automatically launch the set-up in config file manager (Yes, like in Windows ;p). These are options that I currently successfully use for NAUTILUS file manager, You need to set-up all three of them to make it work. | POPUP=YES | FM="nautilus --browser --no-desktop" | USER=vermaden My whole config looks like that now: | USERUMOUNT=YES | POPUP=YES | FM="nautilus --browser --no-desktop" | USER=vermaden | ENCODING=pl_PL.ISO8859-2 | CODEPAGE=cp852 All latest updates are available at GITHUB: https://github.com/vermaden/automount written by Freddie Cash ...> Konqueror (KDE 3.x and 4.x) and Dolphin (KDE 4.x mainly, but I > believe there's a KDE 3.x version) also show automatically > mounted and removable media in the sidebar.

Hi, after some 'fun' with MP3 players I have made some modifications and fixes. Here is a list of whats changed: Fixed bug about inproper exFAT detection, now mounts fine. Fixed bug about creating mount dirs for all attached devices no matter if needed or not. Revised 'detach' section, now removes only directory that is unmounted (if enabled of course). Simplified FAT/NTFS sections, removed additional check as it break some MP3 players default filesystems automount. The latest 1.3 version can be found here as usual: https://github.com/vermaden/automount/ Regards, vermaden
