a lot of this stuff is already broken.

XQuartz is almost unusable now since new windows don't get focus.

There are a lot of bugs in xquartz marked "macos bug"

Another issue I had is that rsync was quietly failing for a lot of stuff I backed up.

I used to rsync -av machine:dir/ dir/ and it stopped syncing stuff.

Turns out they silently replaced rsync with a less capable openrsync.
