It needs patches for bootmenu-n900. I testing it now and later I publish my patches.

I tested it a lot and now it works fine without problem. It is good alternative solution to 009N. Scripts are hosted in my bzr branch on launchpad (from can be downloaded):

It only need lastest version of bootmenu-n900. Maemo5 is installed to /home/maemo5 so /opt is not shared with internal flash. It is now fully dualboot independent system with working bootmenu

For booting it use very ugly hack with overmount, pivot_root and chroot... but it works nice:

Code:

$ mount
rootfs on / type rootfs (rw)
ubi0:rootfs on /mnt/initfs type ubifs (rw,bulk_read,no_chk_data_crc)
/dev/mmcblk0p2 on /home/user type ext3 (rw,noatime,nodiratime,errors=continue,commit=1,data=writeback)
/dev/mmcblk0p2 on / type ext3 (rw,noatime,nodiratime,errors=continue,commit=1,data=writeback)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
tmpfs on /tmp type tmpfs (rw,noatime,size=1024k)
tmpfs on /var/run type tmpfs (rw,nosuid,noatime,size=256k,mode=755)
none on /dev type tmpfs (rw,noatime,size=10240k,mode=755)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,noatime,size=65536k)
