[OpenWrt-Devel] [PATCH 1/3] base-files: sysupgrade: pass "backup" ubus attribute

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

This explicitly tells procd what backup file should be used during
sysupgrade (if any). It's much more generic this way compared to the
magic /tmp/sysupgrade.tgz file that had to be created before a call.
