Trigger a "startipreallocate" event, but only if in RUNNING runstate.
"startipreallocate" is intended to allow an NFS server to be put into
grace on all nodes before any locks are released as part of releaseip
during failover. If node A is leader and initiates a takeover run
then node B may be connected/active but may not have completed
startup. In this case, the attempt to put NFS-Ganesha into grace on
node B will fail, startipreallocate will fail, and the node will be
banned.

rb_test_001.sh runs for 60s even though rb_tree.c is almost never
modified. This generally extends test time by an unreasonable amount
of time.
Add an optional timeout (in seconds) argument to rb_test, defaulting
to 60, and pass 5 from rb_test_001.sh. If anyone ever significantly
updates rb_tree.c then they can run rb_test directly with its default
60s timeout... or for as long as they like.

c6602b686b and

support for the packet push/pull. While adding the testing (for

push functionality was absent. This adds that, along with the test

/etc/os-release is quite universal. It can be found on most Linux
distros and on FreeBSD.
Attempt to use /etc/os-release to detect Red Hat, SUSE and Debian
based distros. If /etc/os-release exists but distro is unknown then
$ID is printed as the detected distro, which will probably result in
sub-optimal behaviour, but when tracing it will at least indicate that
a new distro needs to be handled.
The only way to handle missing /etc/os-release is to set
CTDB_INIT_STYLE - see ctdb.sysconfig(5) for details.
The event script unit tests are updated to use /etc/os-release so
the new logic is exercised.

With a file "home_nodes" next to "public_addresses" you can assign
public IPs to specific nodes when using the deterministic allocation
algorithm. Whenever the "home node" is up, the IP address will be
assigned to that node, independent of any other deterministic
calculation. The line
192.168.21.254 2
in the file "home_nodes" assigns the IP address to node 2. Only when
node 2 is not able to host IP addresses, 192.168.21.254 undergoes the
normal deterministic IP allocation algorithm.

When testparm processes the output of "testparm -v" (which includes
default values) it appears to do global checks (or some other sort of
initialisation logic) for all specified values. This includes a DNS
lookup for the node's hostname, as a side-effect of a libldap
ldap_set_option() call when processing "ldap debug level". If DNS
servers are down then this can induce timeouts, possibly resulting in
monitor timeouts.
Avoid this by using sed to extract configuration values from the
testparm cache file.
This is already shown to work when retrieving share paths, where
testparm is basically used as cat. Update the sed pattern to avoid
matching empty values on the right-hand side of the equals ('=') -
this avoids the default empty path value (and "smb ports" never has an
empty value).
Corresponding test changes:
* 50.samba.monitor.111.sh no longer expects a failure from being
unable to set smb ports, since testparm is no longer used in that
code path.
* smb ports needs to be set in fake smb.conf so it is in the default
output and can be extracted using sed.
* Although testparm --parameter-name is no longer used in
50.samba.script, update the stub implementation (in case it is ever
used again) to extract from fake smb.conf, since "smb ports" is now
set there. The change from $parameter to $param allows a long line
to stay below 80 columns.
