0016-procd-remove-procd-nand-package.patch 24.63 KiB
From: Matthias Schiffer <mschiffer@universe-factory.net>

Subject: procd: remove procd-nand package
We always want to support staged upgrades now, so it's better to include
upgraded into the main package. /lib/upgrade/nand.sh is moved to
base-files.
The procd-nand-firstboot package is removed for now, it may return later
as a separate package.
