Hi,

Recently I had to fix a corrupted pacman db from a 3 month old livecd and realized that this process is not so innocent. Specifically, there is a chance to get a trojaned package on the system simply because the archlinux-keyring package on the iso is outdated. Of course, other similar scenarios are possible, e.g. a fresh install is made from an old livecd, or a server is updated after several months of uptime: new packages are pulled in but signature checks are made using the old keyring currently on the host. So, instead of relying on the discrete updates of archlinux-keyring, wouldn't is make more sense to have a systemd timer/cron job to frequently refresh pacman keyring?

pacman-key --refresh-keys ??

Well, I run this on the home server via a systemd timer, so that I don't forget to do it before an update. It is certainly not necessary on a frequently updated machine, but might be a good idea for a livecd before an installation.

A cronjob does not help you, when you're laptop is off.

I understand your point, i just wanted to illustrate with another practical exemple.
