Re: devd based AUTOMOUNTER
Hi, I have created a PORT at last, its in the 'port' directory in the usual place: https://github.com/vermaden/automount/ Its my first PORT so feel free to bash me about my mistakes ;) After latest 'commits' I think that its ready for day-to-day use. To make 'full advantage' of *automount* install these ports: sysutils/ntfsprogs sysutils/fusefs-ntfs sysutils/fusefs-ext4fuse sysutils/fusefs-exfat I will try to add these ports as OPTIONS in the Makefile later. I will have to think about creating a man page through ... Feel free to submit Your propositions about next changes/development, because I think that I already created everything 'I' needed.

Re: devd based AUTOMOUNTER
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.

This BUG is fixed, I was in wrong assumption, that the script would
be only executed for /dev/da0 but it was executed for every
device/partition node that appeared separately, like /dev/da0,
/dev/da0s1, /dev/da0s2 etc.
Currently there is no knows bugs, but the prepared earlier
'workaround functions' remain just in case.

Re: devd based AUTOMOUNTER
Hi,
new version with new features (and BUGs ;p)
Added check if ntfsfix from sysutils/ntfsprogs is available, if Yes then
try to fix the NTFS filesystem before mouting it.
Added GPL3 License ... just joking ;) ... added FreeBSD License to the file.
Added 'noatime' as a default mount option when possible.
Added TIMEOUT so when an 'orphan' STATE file lock remains, it will be deleted
after a TIMEOUT.
Added /usr/local/etc/devd/automount.devd file instead of messing with the base
system config at /etc/devd.conf.
Added config file to be used from /usr/local/etc/automount.conf file, possible
options are (these are defaults):
MNTPREFIX="/media"
LOG="/var/log/automount.log"
STATE="/var/run/automount.state"
ENCODING="en_US.ISO8859-1"
CODEPAGE="cp437"
DATEFMT="%Y-%m-%d %H:%M:%S"
USERUMOUNT="NO"
Mine config currently has only these:
ENCODING="pl_PL.ISO8859-2"
CODEPAGE="cp852"
USERUMOUNT="YES"
The USERMOUNT otions if set to YES (default to NO) will 'chmod +s /sbin/umount',
so You can click the ^ button on the devices list in NAUTILUS.
These newly mounted devices appear on NAUTILUS sidebar (only with /media
prefix).
But THUNAR and PCMANFM does not do that, You know any other FMs that display
mounted thumb drives/devices?
EXAMPLE: http://i.imgur.com/qdKdl.png
First BUG: (not fixed yet, but workaround already is working)
TEST/BUG/CASE:
Plug in FAT32 and NTFS drives at the same time, when FAT32 device will be
detected first, it will get mounted and the NTFS drive will be mounted TWICE,
so I added __check_already_mounted function to check if it is not already
mounted.
Below are current script and config files.

The state file is needed for automatic umount of fuse-based mounts,
the device that script would be triggered will be /dev/da0 for example
while the 'virtual' device that was actually used for the mount was
/dev/fuse0, that is why I need to track what is mounted and how.
These functions are mostly to keep that 'state file' integral,
to prevent two various event writing at the file simultanously,
which would probable killed the information integrity.
Unmounting the device does not kill integrity at all, I also thought
about that, You may plug the device, do whatever You want, event
change the filesystem there and mount it again, but when You umount
it and unplug it, then the script will umount that device (yes
pointless here at this moment) and remove the entry from state file.

geom config?
I also make use of the list of mounted filesystems, but the problem
with fuse-based devices remain as I stated earlier.

Great advice, I will do that in the next 'release' ;)

Yes but its amd based.

The labels are only 'an addition' to appearing device nodes at /dev,
Yes it would be nice to see that /dev/msdosfs/BACKUP is mounted
instead of /dev/da0s1, but I will have to make a lot of additional
check to see if that new label is part of that or other device etc.

I probably will try to do that, but I think it stil needs polish ;)
written by Lars Engels ...
> And please don't hardcode polish locales in mount_msdosfs :-)
I already changed that, I also plan to create simple config file,
it was just not 'the most important thing' that I was dealing
with at that time, its easy to move options into variables,
its harder to make script work the way it should ;)
But thanks for suggestion, good point.

Why not keep it stateless, unmounting by hand would kill integrity.
Usage of `file` is a big security concern.
I think geom config and list of mounted file systems should be
sufficient for collecting information at runtime. Although it may not be
that easy for disks without partitioning.
I'm using a python script for mounting/unmounting removable disks,
but having similar tool written in sh would be great.

Hi,
Should your script be written like an rc.d script, so that one can
enable/disable this automounting from /etc/rc.conf?

Re: devd based AUTOMOUNTER
Added a check if ntfs-3g is available, if not then mount_ntfs is used instead.
Added deleting of empty directories at ${MNTPREFIX}.
Added ${MNTPREFIX} to be set to /mnt or /media according to preference

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.

Currently You can add these options to filesystem specific mount command, but
its definitely possible.

> 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.

I have done everything to check that and to omit that, if not, then submit a
BUG ;)
Thanks for suggestions Matt.

Some things to consider/test:
How do I set custom flags, like nosuid,noatime,nodev,noexec,async (or
sync) for mounts?
What if make a usb drive with an illegal name, existing name or other
dangerous values?
Can I use the automounter to either mount over another mount to
impersonate it, or can I overwrite arbitrary files or directories?
Some
