Subject: [sysupgrade] Don't try to pivot to new ramfs if already running on one
X-Git-Url: https://git.rohieb.name/openwrt.git/commitdiff_plain/2eba59293a00599cc62412cb3f36eec5015477ea?hp=2eba59293a00599cc62412cb3f36eec5015477ea

[sysupgrade] Don't try to pivot to new ramfs if already running on one
This patch allows the sysupgrade script to continue with the upgrade if
openwrt is already running on a ramfs. This allows the use of the sysupgrade
script as an _installer_ when running from an iso image. A user could boot the
system from a bootable cd and invoke sysupgrade -n <URL> to write an image to
the hard disk or CF.
