Subject: systemd: pass --root in prerm if running on host
X-Git-Tag: lucaceresoli/bug-15201-perf-libtraceevent-missing~35079
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d01da862d10d9544f8da846b577cf955041d4c0c;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

systemd: pass --root in prerm if running on host

If a systemd image is built without a package manager then packages will be
removed from an image during rootfs generation, but without passing --root the
systemctl will look on the *host* system.
