Subject: main: write pid file even when not daemonizing
X-Git-Tag: 0.8.4~38
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b1e9022f119d461dddc9569d90533fb0cf726f52;p=thirdparty%2Fplymouth.git

main: write pid file even when not daemonizing

This commit moves the pid file writing code to main
from ply_create_daemon, so that it gets run even when we
plymouthd isn't daemonized.

This is more symmetrical, anyway, since unlinking of the pid
file is handled in main.
