fwiw, since most incompatibilities are in the interface to the kernel,
this is actually likely to last _less_ long than using shared libc with a
hack to allow using (e.g. by copying) the most recent libc from /usr/lib
over the top.

libc rarely changes in a way which is _really_ backwards-incompatible
way for most programs (when functions are removed from libc, obviously
they are not going to be ones which are frequently used. and types of
parameters for existing functions in libc don't change much). whereas
kernel/userland interfaces change relatively often (but are often not
noticed because a libc change, even one _without_ a bump, will fix
them).
