First off, let me say that I've read, re-read, and again read the sticky re:Hal and 12.0. Many times in the past, and again today.
I've just completed a fresh 12.2 install (having borked a perfect 12.0 install...don't ask.)
Anyway, I have an Archos 605 pmp, and under 12.0, using ivman and pmount, I was, for the most part, able to have my pmp automounted, whether in X or at the cli. This enabled me to do nightly syncs and playlist generation via cron. For the most part, due in large part to the sticky (thanx folks!) I don't recall it being particularly difficult.
However, upon trying to accomplish the same feat in 12.2, I feel defeated. Nothing I tried would work all the time
. Formerly, when I plugged in the pmp, it would be read as /dev/sd? and auto-mounted to /media/A605. It's because of this behaviour that I was able to create scripts, and to invoke them via cron.
In 12.2, sometimes the device would be seen as /dev/sda1, and mounted /media/A605; other times mounted as /media/sda1; other times not mounted at all, unless & until I clicked on it in Thunar, or manually mounted it via cli. Unmounting also proved to be an issue. Sometimes pmount would allow it - other times it would error out, saying I wasn't the one who mounted it.
In running ivman, I could see that there were sometimes mounting issues (via pmount); sometimes it wouldn't mount because it was determined that is wasn't a removable device. I could whitelist the pmp in pmount.allow, but it would have to be as /dev/sda1. Labels & UUIDs weren't allowed.
Of course the major issue in this case, besides not being certain that the device was mounted at all, is that I couldn't be sure that the device would be read as /dev/sda1, especially if there were other usb storage devices in play.
Getting to the point - I ended up putting a line in fstab:
LABEL=A605 /media/A605 auto auto,users,rw,dmask=0022,fmask=0133 0 0
and I created a udev rule, 99-mount.rules:
#run mount -a everytime a block device is added/removed
SUBSYSTEM=="block", run+="/bin/mount -a"
This, apparently, does the trick.
I'm curious as to whether this is the way it's all supposed to work, or what I may have missed in the first place, or whether there's any drawbacks to what I've done.
