Weird, because there weren’t that many EFI variables, but df -h also reported that efivars was full:

Weird, because there weren’t that many EFI variables, but df -h also reported that efivars was full: It wasn’t due to a glut of boot entries either; I’m pretty keen on keeping the old ones cleared out, so we only had a few on here.
