Think about booting over network. Or having /usr on another drive. Including even network drive. Think about dumb terminals(wrong cetury) thin clients. For example they can use small disk to quickly boot wihout downloading kernel and initramfs and use NFS for /usr and /home.
True, network boot is not best example. Shared /usr is much better one. For example if you are school that wants to buy 100 thin clients for very cheap.
I’m curious why the separation between these still exists, because a bunch of distributions symlink all of these to
/usr/bineither wayThink about booting over network. Or having /usr on another drive. Including even network drive. Think about
