[pve-devel] [PATCH pve-kernel-meta v2 3/8] proxmox-boot-tool: sort and remove duplicates on clean

[Stoiko Ivanov]

This is mostly in preparation for renaming pve-efiboot-uuids into
proxmox-boot-uuids, but can help in general (since each duplicate uuid
causes excessive disk i/o upon kernel upgrades).
