In just one year — 82% more awesome?
I'd really like this to stay below 200MB as a competitive threshold.
Or, if we're going to be bigger than that, be bigger for REASONS, not
just accretion.
tl;dr: grub2 is a lot to blame, but there seem to be some new
questionable dep chains from systemd, and general dep growth across the
board.

Thanks for noticing :)
Note coreutils also got a new ./configure --enable-single-binary
option recently to build all tools to a single binary like busybox.
The tradeoff is somewhat higher startup cost, and RAM cost,
due to all shared libs being linked. Chromium is using this
build configuration I understand.
cheers,
