Description: Whenever netplan and a configuration is in place, systemd daemon-reload of exactly 60 seconds (e.g. more often than not a pacman -Suy is run) will cause a hang (of the daemon-reload process, along with the shell if triggered from a user shell, and most things network-related, and possibly other services?).

As a workaround, I've edited /etc/nsswitch.conf as such:

# group: files [SUCCESS=merge] systemd
### netplan bug workaround
group: files systemd

However, I'm not actually sure what this edit does and what are the possible side-effects. It does remove the hangs.

Additional info:
* package version netplan-0.107-3
* There is an upstream pull request here for fixing the underlying problem. https://github.com/canonical/netplan/pull/304
* There are bug reports elsewhere, such as here: https://bugs.launchpad.net/netplan/+bug/1999178

Steps to reproduce:

- Have a configuration in /etc/netplan. I'm not sure all configs will trigger the bug (as I've understood the bug report, any parseable config will trigger the bug).
- Do anything which cases a daemon-reload or trigger it manually.

Observed results:
- Daemon-reload will take exactly 60 seconds (+ whatever it did originally), during which the system is mostly useless.

Expected results:
- Daemon-reload should proceed normally in a sensible time frame.
