@jmguzik thanks for the PR. The changes LGTM, but the tests are unhappy and I can't quickly figure out why. Maybe a known flake @edsantiago ?

Compose tests always flake these days. I've restarted.

int test failure is weird:

Failed to create /user.slice/user-13251.slice/session-3.scope/init.scope control group: Permission denied
Failed to allocate manager object: Permission denied
Failed to allocate manager object, freezing.
Freezing execution.

I'm just going to restart it and hope it was a flake.
