gollark: Hmm, that's annoying, I ran `pacman -Syu` on my server and it just keeps saying "Import PGP key whatever [Y/n]" and ignores my input.
gollark: How big's the old thing's SSD?
gollark: Arch only fills about 8GB on my USB stick, so you should be okay.
gollark: Hmm. SSD or HDD? Either way, Arch should work pretty well on those.
gollark: What sort of spe¢s does it have?
