Subject: sysupgrade: set UPGRADE_BACKUP env variable
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0f3c1366bb927e483abfae23dee0d15e26f87064;p=oweals%2Fprocd.git

sysupgrade: set UPGRADE_BACKUP env variable

It points to the backup file to use duing sysupgrace process. Right now
it's hardcoded to the /tmp/sysupgrade.tgz. Once all cleanups are in
place "sysupgrade" ubus method should be extended to allow passing any
custom path.
