Correct. As long as IMA is also measuring the upper inode then it seems
like you shouldn't need to do anything special here.
Unfortunately IMA does not notice the changes. With the patch provided in the other email IMA works as expected.
What sort of fs are you using for the upper layer?
jffs2:
/dev/mtdblock4 on /run/initramfs/ro type squashfs (ro,relatime,errors=continue)
/dev/mtdblock5 on /run/initramfs/rw type jffs2 (rw,relatime)
cow on / type overlay (rw,relatime,lowerdir=run/initramfs/ro,upperdir=run/initramfs/rw/cow,workdir=run/initramfs/rw/work)
