Subject: profile/osc-context: move and extend check for TERM=dumb
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=705e2ef19418f14ff9b90c9645391d500d06be7b;p=thirdparty%2Fsystemd.git

profile/osc-context: move and extend check for TERM=dumb

Let's do the check early and skip most of the file if appropriate. Also, treat
missing $TERM same as "dumb". We're almost certainly at a dump terminal in that
case.
