Bug#1125054: partman-efi: on install with one of the "Guided - user entire disk" options also wipe old efivars? efi uefi

package is a guess, please move as needed.

Installed with "Guided - use entire disk and set up encrypted LVM" and
was surprised to see logs mentioning a previous very brief Kali install
that had been done on the same machine.

Should old UEFI vars be wiped if using one of the entire disk partman
recipes?
