Hello, Gentoo.

I've been thinking about the problem of the conflation of every
executable into /usr.  If /usr isn't on /, the system can't boot without
special preperations.  Nothing new here.

The method usually discussed is to copy the booting software into an
initramfs on a partition other than /usr, and use this to mount /usr.

My question: what, technically, prevents me from copying the booting
software instead to /sbin and booting the system that way?
