Arch Linux

When rebooting in the middle of an update, the lockfile is preserved, even though no process is accessing it anymore.

This leads to unnecessary confusion and can be remedied by storing it in a transient directory like /tmp or /run, probably /run/lock is sensible as suggested in https://bugs.archlinux.org/task/65234

Solving this would bring all related issues forward a good bit:
