[systemd-devel] [PATCH WIP] shell-completion: Change zsh boot id completion

[William Giokas]

Previously we put the boot offset and boot ID into the completion, now
we use something similar to the coredumpctl completion, but only with
the boot offsets.
---

This is just something I'm working on, but would like some input. I'm fine
with it not having the boot ID's output, but that may be unacceptable.
