Subject: base-files: sysupgrade: abort if config backup fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=72489ebeb65fd1e1d77e8d9fbe105827a98dbf03;p=openwrt%2Fstaging%2Frmilecki.git

base-files: sysupgrade: abort if config backup fails

Sysupgrade shouldn't proceed, if the backup of the configuration
fails because tar (or gzip) exit with a non-zero code.
