Upgraded to your build last night - all went well. Haven't noticed any wi-fi problems due to the new Brodcom driver yet as been reported by others in the dd-wrt forum.

Noticed that Frater's optware scripts doesn't work as intended due to the new mount strategy. What I had to do was the after flashing was the following:

- Mount the Optware partition manually to "opt" using the UUID

- Reboot

After this all worked as intended

One of the nice things about Frater's service scripts is the factdefault script. In your recent image this script would kick-in automatically when a new image is flashed and restore values from the most recent backup.

The new mounting strategy involves a manual step. Another advantage of the old mounting scheme is that the scripts kick-in if the router loose it's nvram settings.

Is there a way to get Optware running automatically after a clean flash like before? Since the default settings now will not mount the Optware partition to "opt" Optware will not start "automagically".

Good point and I have already included LABEL support in busybox's mount, so all I need to do is to check if UUID for opt is set, if not(e.g. after reset) mount any partition that is labeled "Optware" to /opt.

So basically this is adding one line in my mount code:-)

Great!! When will this enhancement be available?

Noticed that you posted a revision. Is the mount fix implemented?

Nope, I'm currently compiling builds that include the new automount feature, after that I run a quick test.

OK, I ran a few tests and it works as expected, but I saw a few other problems, which should be fixed before I release another build.

Kong thanks for playing nice with Frater's OTRW. Can't wait till your next release that mounts Optware partition to /opt

I imagine this would render the following code on my .rc_startup not needed anymore [Please confirm].

ord() {
printf '%d' "'$1"
}
insmod mbcache
insmod jbd
insmod ext2
insmod ext3
pn=1
prt="3172837 sd.$pn"
n=1
while [ $n -lt 500 ] ; do
if [ -z "$p" ] ; then
p=`grep "$prt" /proc/partitions | awk '{print$4}'`
pc=`echo $p | cut -b3`
else
grep -q '/opt' /proc/mounts && break
mknod /dev/$p b 8 $((16 * (`ord $pc` - 97) + $pn))
mount -o noatime /dev/$p /opt
fi
let n+=1
sleep 5

Hi zoomlink,

yes once it works as intended this is obsolete. I just completed my code and I'll test it later on. I already tested mounting yesterday and it worked fine now, tested with 3 drives.

The new behaviour, whenever a disk is connected/removed is the following:

All partitions from all discs will be mounted, default strategy is to mount a partition that is labeled Optware to /opt and a partition labeled Jffs to /jffs
All other partitions will be mounted to /tmp/mnt. If uuids are defined they will override which partitions gets mounted to /opt or /jffs. Thus if you do a router reset Optware/Jffs labeled partitions will be already mounted to the correct location.

The new code also takes care of stopping included services in order to cleanly umount all partitions on a reboot.

The Disk Info will show mountpoints.

If you remove a disk while the router is running the mountpoints will be removed.

So basically this is a complete rewrite of the hotplug mechanism for usb drives.

Only thing missing now is a button that allows you to umount partitions for a certain drive in order to remove it while the router is running.

My friend Kong.... hope you had a good weekend.

When can we expect your new revised build? The anticipation is killing me.
