Subject: build: preserve profiles.json between builds
X-Git-Tag: mikrotik~1857
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a463b96241fbc2d142982387eaed9989e201ac7a;p=openwrt%2Fstaging%2Fchunkeey.git

build: preserve profiles.json between builds

Keep other profiles.json content if the data belongs to the current
build version.

Also useful for the ImageBuilder, which builds for a single model each
time. Without this commit the profiles.json would only contain the
latest build profile information.
