Well, this is about very few files only. AFAICS only systemd/udev, kmod,
ld.so need binary caches around this early during boot. It
sounds a bit like overkill to introduce an entirely new root level
hierarchy for that.

Note that beyond caches there are a number of non-text-files in
/etc. For example /etc/localtime,
/etc/selinux/targeted/policy/policy.27, /etc/pki/*.db, /etc/aliases.db,
/etc/ld.so.cache, /etc/prelink.cache and so on. I am not convinced that
text file vs. binary file is the best check to decide whether something
belongs in /etc or not.
