Github Actions: Arch about labwc

[Consolatis]

My memory is a bit fuzzy regarding this but AFAIR it was required to call --init because the keyring in the image used wasn't working otherwise. Regarding the runtime, Arch, Debian and Void have a runtime of about 1 to 2 minutes compared to the FreeBSD VM with 3 to 4 minutes so shaving of a few seconds from Arch isn't really worth it.

Currently there is another issue with Arch in that the mirror used sometimes fails deliver content and basically idles with some kb/s (or even bytes/s). We had similar issues in the past with other distros so I assume it is a temporary problem and will fix itself over time.

Odd, but maybe I didn't compare it with enough runs. I particulary noticed https://github.com/labwc/labwc/actions/runs/8254909096/usage and with a quick glance the runs around Arch were the slowest.
And then I noticed the --init call, which can take some time. Couldn't see any numbers that were indicating what exactly took the time and assumed the keygen. So if you say there are also mirror problems that seems to be more likely if you can say from experience, that the running times were lower. Cemented by newer runs/figures that definitively take less time.
Nevertheless, the call to --init should be superfluous, as the image adds and intializes the stuff. And after taking a quick look at pacman-key running --init on the populated dir shouldn't do a thing.

Regarding mirrors: To avoid issues with mirrors the following could be added in whatever way:

pacman -Sy
pacman -S pacman-contrib
curl -s "https://archlinux.org/mirrorlist/?country=US&country=DE&protocol=https&use_mirror_status=on" | sed -e 's/^#Server/Server/' -e '/^#/d' | rankmirrors -n 5 - > /etc/pacman.d/mirrorlist
pacman -Syyu --noconfirm
(...)

or alternatively

pacman -Sy
pacman -S reflector
reflector --latest 5 --protocol https --sort rate --country 'USA,Germany,' --save /etc/pacman.d/mirrorlist
pacman -Syyu --noconfirm
(...)

With reflector being the faster solution in my experience.
