This is misleading in two ways.
1) You're talking as if having a functionally merged /usr and / system
(i.e., many programs needed by the sysad to fix a non-booting system
are in /usr, and programs in /usr will break if /usr is not in sync
with /) is a weirdo corner case. It is NOT. It is very likely how the
vast majority of Linux systems on the planet work. Separate /usr is
itself the weirdo corner case. It was in fact a weirdo corner case
since day 1.
2) You're talking as if Lennart or whoever is breaking into your
systems and actively preventing you from customizing it to boot a
separate /usr. If this is the case you _really_ need to change your
ssh keys, they wiped that vulnerability a couple years ago.
Nobody's preventing you from building a custom system that cleanly
separates / and /usr. But hey, don't pretend that even Gentoo does it
correctly. Besides the equery tests in this thread, I've never
personally confirmed that any other distro does - and Fedora cleanly
admits that they don't.
