After a little reading I'm guessing that gamin and gam_server are
attempts to rewrite fam. Googling for gam_server brings up countless
pages on it's misbehaviour with regard to CPU usage (gam_server is
eating up 40% of my cpu and the like).
Is there any way to combine Hal, geom and the automounter into a more
robust solution?
E.g. I fdisk and disklabel my USB stick with a Native FreeBSD
filesystem. Then I use
tunefs -L "myusbstick" /dev/da0s1a
to label the filesystem for geom. Now when I plug in the USB stick I
get an entry in /dev/ufs/myusbstick.
Now I configure amd with a map like this:
/default type:=program;\
mount:="/usr/sbin/mount mount /dev/ufs/${key} ${fs}";\
unmount:="/usr/sbin/umount umount ${fs}";
* fs:=${autodir}/${key};
In case you are interested you use a program mount because amd never
times out a ufs mount. Command to mount the pendrive:
ls -l /<map>/<label>/
To unmount the filesystem:
amq -u /<map>/<label>
Finally to use something like this with gam make sure to change gam's
time out to be at least twice as long as amd's
