Yes, that happens only if it explicitly requested, i.e. if there are valid
mount points in .wks file

I also didn't see it till last message from Otavio. Now I do - they
don't want to change .wks files. They're using standard wks from
scripts/lib/wic/canned-wks or from standard layers and they don't want
to duplicate them when they don't want rootfs modifications.

It could be a valid reason to have --no-fstab-update option I think.
However, I'm still not 100% convinced I'm ok with this if nobody else
objects.
