works until it breaks. :)

I have a pending patch that fixes restarting cleanupd in a cluster on
a node that is banned.

Branch with the fix, your patches and an added test for my patch on
top:
<https://git.samba.org/?p=slow/samba.git;a=shortlog;h=refs/heads/cleanupd>

On my system configured with --prefix=/opt/samba this breaks at:

$ make test TESTS=ctdb_ban
...
UNEXPECTED(failure):
samba3.blackbox.ctdb_ban(clusteredmember:local).ctdb_ban(clusteredmember:local)
REASON: Exception: Exception: ../ctdb/client/ctdb_client.c:293 Failed
to connect client socket to daemon. Errno:No such file or directory(2)
../ctdb/common/cmdline.c:167 Failed to connect to daemon
Failed to init ctdb
Failed to read nodes file "/opt/samba/etc/ctdb/nodes"
Is this node part of a CTDB cluster?

^CTOP 10 slowest tests
ERROR: test failed with exit code -2
Makefile:17: recipe for target 'test' failed
make: *** [test] Error 254

Guess we're still missing your patches for ctdb build with a prefix !=
/usr ?

Cheerio!
