I've implemented a patch for fanoush's bootmenu, which does the following:

* Adds ability for $MENU_${MENU_IDX}_LINUXRC that at the end of boot menu selection mounts selected rootdev and exec's /linuxrc on the partition - leaving the boot process entirely to linuxrc instead of going through initfs's linuxrc which does funky things to the /var/run, /tmp etc. This makes it a lot easier to port Linux based systems to the tablet as we don't have to deal with the oddities of the boot process.

* Adds a "standard" bootmenu.conf, which loads boot menu items from /etc/bootmenu.d/*.item on rootfs (mounting ro, and unmounting afterwards) and inserts them into boot menu on boot time. This adds 1-2 seconds of boot time, but it has the advantage of allowing Clone-to-SD, Deblet, etc to insert boot menus easily when installing - and hoping to make something like this standard in some way to allow for easy boot menu stuff / multiboot.

Example item:

/etc/bootmenu.d/deblet.item:
ITEM_NAME="Deblet"
ITEM_ID="deblet"
ITEM_DEVICE="mmcblk1p2"
ITEM_MODULES="mbcache jbd ext3"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime"
ITEM_LINUXRC="yes"

Patch can be found on http://bsd.tspre.org/~stskeeps/bootm...uxrc.patch.txt

I'd like some comments from any others doing bootmenu modification and hear if this could be a good way to have a shared boot menu system that allows for easy multibooting and not messing up eachothers boot menu settings - that you would use
