[Pacemaker] use_logd or use_mgmtd kills corosync

[Devin Reade]

I was following the instructions for a new installation of corosync
and was wanting to make use of hb_gui so, following an installation
via yum per the docs, built Pacemaker-Python-GUI-pacemaker-mgmt-2.0.0
from source.

Starting corosync works normally without mgmtd in the picture, but as
soon as *either* of the two lines are added to /etc/corosync/service.d/pcmk,
corosync fails to start with no diagnostics in the logfile or syslog:
    use_logd: 1
    use_mgmtd: 1

I ran 'strace corosync -f' and got rather uninformative information, the
tail end of it shown here:

statfs("/etc/corosync/service.d", {f_type="EXT2_SUPER_MAGIC", f_bsize=4096,
f_blocks=507860, f_bfree=388733, f_bavail=362519, f_files=524288,
f_ffree=517073, f_fsid={0, 0}, f_namelen=255, f_frsize=4096}) = 0
getdents(3, /* 3 entries */, 32768)     = 72
stat("/etc/corosync/service.d/pcmk", {st_mode=S_IFREG|0644, st_size=101,
...}) = 0
open("/etc/corosync/service.d/pcmk", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0644, st_size=101, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x2acb16dd5000
read(4, "service {\n \t# Load the Pacemaker"..., 4096) = 101
close(4)                                = 0
munmap(0x2acb16dd5000, 4096)            = 0
close(3)                                = 0
exit_group(8)                           = ?


Any thoughts?
