devd based AUTOMOUNTER

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:

#! /bin/sh

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
LOG="/var/log/automount.log"
STATE="/var/run/automount.state"
DATEFMT="%Y-%m-%d %H:%M:%S"

__create_mount_point() { # /* 1=DEV */
  MNT="/mnt/$( basename ${1} )"
  mkdir -p ${MNT}
}

__state_lock() {
  while [ -f ${STATE}.lock ]; do sleep 0.5; done
  :> ${STATE}.lock
}

__state_unlock() {
  rm ${STATE}.lock
}

__state_add() { # /* 1=DEV 2=PROVIDER 3=MNT */
  __state_lock
  echo "${1} ${2} ${3}" >> ${STATE}
  __state_unlock
}

__state_remove() { # /* 1=MNT 2=STATE 3=LINE */
  LINE=$( grep -n -E "${1}$" ${2} | cut -d : -f 1 )
  sed -i '' ${3}d ${2}
}

__log() { # /* _at_=MESSAGE */
  echo $( date +"${DATEFMT}" ) ${_at_} >> ${LOG}
}
