AFAIK it's still needed. BTW, it looks like this is partly taken from
the code I posted here, so FWIW I've slightly improved/simplified it:
mount_drive () {
rootdev="$1"
COUNTER=0
while [ ! -b "$rootdev" ] && [ $COUNTER -lt 10 ]; do
echo "mount sleep for $rootdev" >>/tmp/stef
sleep 1
let COUNTER=COUNTER+1
done
mount "$rootdev" /mnt && [ -x /mnt/sbin/init ] && {
echo "mounted $rootdev" >>/tmp/stef
. /bin/firstboot
pivot /mnt /rom
exit
}
}
(cd /etc/modules.d && load_modules *)
# GPIO 6 on WL-700gE is the `copy' button; if the button is released,
# gpioctl returns 0, and it return 64 if it is pressed.
# GPIO 4 on WL-700gE is the `ezsetup' button; if the button is released,
# gpioctl returns 0, and it return 16 if it is pressed.
if gpioctl get 6 >/dev/null && gpioctl get 4 >/dev/null; then
# FIXME: This device name should come from a CONFIG_setting.
mount_drive /dev/hde1
mount_drive /dev/sda1
fi
I personally add the above to /sbin/mount_root just after jffs2_ready.
The main difference is that I simply load all the modules included in
the squashfs, which makes this code more portable while making it
simpler at the same time.
OTOH, clearly, the `gpioctl' part of the code is not portable so you'll
probably want to get rid of it (tho I find it very convenient, since
I can then circumvent a messed up /dev/hde1 by pressing the ezsetup
button during the boot process; kind of like a built-in rescue-CD).
As mentioned, I think this code could be integrated at some point, and
for that we'll want to be able to specify the root device (/dev/hde1 in
the case of WL700gE) via a CONFIG_* variable.
