Franck Bui	acc28e2e30	core: make sure initrd-switch-root command survives PID1's killing spree (#4730) ... This is a different way to implement the fix proposed by commit a4021390fe suggested by Lennart Poettering. In this patch we instruct PID1 to not kill "systemctl switch-root" command started by initrd-switch-root service using the "argv[0][0]='@'" trick. See: https://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons/ for more details. We had to backup argv[0] because argv is modified by dispatch_verb().	2016-11-24 18:52:04 +01:00
Franck Bui	a4021390fe	core: consider SIGTERM as a clean exit status for initrd-switch-root.service (#4713) ... Since commit 1f0958f640, systemd considers SIGTERM for short-running services (aka Type=oneshot) as a failure. This can be an issue with initrd-switch-root.service as the command run by this service (in order to switch to the new rootfs) may still be running when systemd does the switch. However PID1 sends SIGTERM to all remaining processes right before switching and initrd-switch-root.service can be one of those. After systemd is reexecuted and its previous state is deserialized, systemd notices that initrd-switch-root.service was killed with SIGTERM and considers this as a failure which leads to the emergency shell. To prevent this, this patch teaches systemd to consider a SIGTERM exit as a clean one for this service. It also removes "KillMode=none" since this is pretty useless as the service is never stopped by systemd but it either exits normally or it's killed by a SIGTERM as described previously.	2016-11-23 16:31:24 +01:00

Michael Biebl	7b40ce553f	build-sys: don't hard-code binary paths in initrd-*.service ... Instead use @bindir@ for udevadm and @rootbindir@ for systemctl.	2013-03-09 10:05:01 +01:00
