Subject: Track "attached" versus "redirected" separately
X-Git-Tag: 0.6.0~37
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a739a8ecafb02cdbaa8a3a2e15030bfe8549966c;p=thirdparty%2Fplymouth.git

Track "attached" versus "redirected" separately

We only want to try to attach the terminal session
to a terminal if it's not already attached.  It may
be legitimately unredirected if plymouth:nolog is
passed.
