Another complication:
- while gcc normally observes the dictum that the presence of "-g"
should not affect the executable code/data at all, this may not
completely hold even now; as above, we can hope that build-id
catches this case, or else we can find some other mechanism to
assert byte-for-byte equality between the regen'd .o and the
sliced & diced & linked copy in .../vmlinux or .../foo.ko
- what if vmlinuz (compressed bootable image) is the only residue,
and the linked vmlinux is not available (as in distro packages);
maybe simply this on-the-fly widget cannot apply there
