Actually, even on non-modern disk sizes that split isn't good. A decade
ago, on N700/N800/N900 Nokia had a tiny boot $DISK and another 64GB in size
but noticeably slower. It turned out that / vs /usr is no good for them,
and they instead opted for most non-essential binaries on a separate
partition on the 64GB eMMC. Both / and /usr were on the small disk with
most programs symlinked to the filesystem on /opt .
