mtd2.img: make better use of UBIFS space #3

Closed davygravy closed 3 years ago

davygravy commented 3 years ago

rootfs.cfg for creating the UBIFS seems to not make good use of space. Push out to 31MiB.

NOTE: at 32MiB, the UBIFS rootfs would not boot - VFS sync error and kernel panic at boot. vol_size=31MiB gives more than 27MiB in df -h with about 3.8MIB unused.

root@rescue:~$ df -h
