add blkid method for uuid
Hello, using this script, we periodically encountered the problem that "uuid" was not defined on some sections. In the process of studying the problem, it became clear that partition have uuid, but lsblk cannot determine it and gives an empty string. At the same time, BLKID handles uuid detection, I suggest adding BLKID as a fallback way to get uuid to minimize situations when uuid is present but cannot be detected.
We use this script not only for installing archlinux we install ubuntu debian centos hosts with arch style installation, so we run this script inside custom livecd with rocky linux 8 not in chroot.
we test this changes and problem goes away.
situation when no uuid displays look like this, sda2 have ext4 fs and mounted with mount /dev/sda2 /mnt/boot command.
You can use uuid=$(blkid -s UUID -o value "$1" 2>/dev/null) to get UUID, which I believe is simpler and more readable. Also, maybe use [[ ]] instead since it's used all other places?
thanks for the clarifications on the blkid syntax, your example is much more concise.
However, using mount --make-private instead of a tmpfs for /run as
suggested in https://github.com/archlinux/arch-install-scripts/issues/24
might be a better fix for this problem.
Could you please test that with /run/udev present in chroot, lsblk can
get the uuids as well?

Closing in favour of the --make-private implementation.
