[systemd-devel] [PATCH] rpcbind: add support for systemd socket activation

Thu Dec 22 17:05:27 PST 2011
Making rpcbind sockect activated will greatly simplify
its integration in systemd systems. In essence, other services
may now assume that rpcbind is always available, even during very
early boot. This means that we no longer need to worry about any
ordering dependencies.
This is based on a patch originally posted by Lennart Poettering:
<http://permalink.gmane.org/gmane.linux.nfs/33774>.
That patch was not merged due to the lack of a shared library and
as systemd was seen to be too Fedora specific.
Systemd now provides a shared library, and it is shipped by defalt in
OpenSUSE in addition to Fedora, and it is available in Debain, Gentoo,
Arch, and others.
This version of the patch has three changes from the original:
* It uses the shared library.
* It comes with unit files.
* It is rebased on top of master.
Please review the patch with "git show -b" or otherwise ignoring the
whitespace changes, or it will be extremely difficult to read.
Comments welcome.
v2: correctly enable systemd code at compile time
handle the case where not all the required sockets were supplied
listen on udp/tcp port 111 in addition to /var/run/rpcbind.sock
do not daemonize

Thanks to Cristian for testing. The testcase I had been using was entirely flawed,
the code did in fact not work at all. Sorry about that!
This time around it should work :-)
