Hi Guys
not sure how the duel boot side of this all works
but if there is going to be partitions changes for v22
i'll throw this out there as idea atm
is it conceivable as UBI has it's own error correction
that both areas of rootfs1 & rootfs2 can be concatenated
so we would end up with 2x36M (72M)
even if flash file size is limited to 4+36M
can leave the 2 copy of the kernels & boot from ether
but would both access the same fixed location UBI concatenation
not sure how this will effect sysupgrade & making sure both kernels are the same
but the good thing would be with the same UBI's no matter witch kernel booted
the config would be the same with double the space for programs like Samba4 etc
