There were several hard-coded values for run directory around the code.
Also, some tools are DM specific only, others are LVM specific and there
was no distinction made here before. With this patch applied, we have
this cleaned up a bit (subsystem in brackets, defaults in parentheses):
[common] configurable PID_DIR (/var/run)
lvm [lvm] configurable RUN_DIR (/var/run/lvm)
configurable locking dir (/var/lock/lvm)
clvmd [lvm] configurable pid file (PID_DIR/clvmd.pid)
socket (RUN_DIR/clvmd.sock)
lvmetad [lvm] configurable pid file (PID_DIR/lvmetad.pid)
socket (RUN_DIR/lvmetad.socket)
dm [dm] configurable DM_RUN_DIR (/var/run)
cmirrord [dm] configurable pid file (PID_DIR/cmirrord.pid)
dmeventd [dm] configurable pid file (PID_DIR/dmeventd.pid)
server fifo (DM_RUN_DIR/dmeventd-server)
client fifo (DM_RUN_DIR/dmeventd-client)
The changes briefly:
- added configure --with-default-pid-dir
- added configure --with-default-dm-run-dir
- added configure --with-lvmetad-pidfile
- by default, using one common pid directory for everything
(only lvmetad was not following this before)
