On bare-metal installs, `lsblk` reports the USB stick the live ISO
booted from as TYPE=disk, so it showed up in the drive picker
alongside the real install target — a user could in theory pick the
USB they had just booted from. `findmnt /run/archiso/bootmnt` resolves
the boot partition and `lsblk -no PKNAME` walks it up to the parent
disk; that disk is dropped before scoring. On a normal box neither
file nor mountpoint exist and the picker is unchanged.
