Are Ubuntu software updates (apt-get update, upgrade) also updating files of the EFI partition (/boot/EFI)?
I ask because I'd like to image backup Ubuntu system partition only. Depending whether updates also touch EFI partition or not, I also need to backup that one on top of the Ubuntu system partition.
I have an initial image backup of both (done right after fresh install of Ubuntu), EFI and Ubuntu system partitions.
I.a.w. ... do I need to include the EFI partition in my weekly Ubuntu system partition image backups because it's files may change due software updates?
