Slow/broken systemd bash tab completion (Launchpad 1471723)

[Wiebe Cazemier]

Hi, 

There is a long standing bug [1] about systemd slow tab completion. The latest development is that the command to collect systemd units, 'journalctl -F _SYSTEMD_UNIT', takes a (seemingly) infinite amount of time to complete. See it in action on [2].

I've observed this behavior in Ubuntu 18.04 and Ubuntu 22.04.

It really makes it hard to work journalctl. If you press tab by accident, bash freezes.

I was hoping this bug can be given some priority, preferably in all Ubuntu LTS releases.

Regards,

Wiebe
