systemd: add a generator for the rpc_pipefs mountpoint

2017-04-10T11:10:45+00:00

The nfs.conf has config options for the rpc_pipefs mountpoint.
Currently, changing these from the default also requires manually
overriding the systemd unit files that are hard-coded to mount the
filesystem on /var/lib/nfs/rpc_pipefs.

This patch adds a generator that creates a mount unit file for the
rpc_pipefs when a non-default value is specified in /etc/nfs.conf, as
well as a target unit file to override the dependencies for the systemd
units using the rpc_pipefs.  The blkmapd, idmapd, and gssd service unit
files have been modified to define their dependencies on the rpc_pipefs
mountpoint indirectly via the rpc_pipefs target unit file.  Since both
rpc-pipefs-generator.c and nfs-server-generator.c need to convert path
names to unit file names, that functionality has been moved to
systemd.c.

This patch also removes the dependency on the rpc_pipefs from the
rpc-svcgssd.service unit file.  rpc.svcgssd uses the sunrpc cache
mechanism to exchange data with the kernel, not the rpc_pipefs.

systemd: Remove the nfs-config.service

2016-12-20T18:29:04+00:00

Now that we have /etc/nfs.conf, a lot of configuration can be
read directly.  So nfs-config isn't really needed any more.

Some distributions allow command-line arguments for various
daemons to be set in an environment file (/etc/sysconfig,
/etc/defaults).
Passing these through /etc/nfs.conf is not possible.

Instead, a distro that needs this functionality can create drop-in
files which select the required value.  As no commands are given
default arguments by systemd unit files, the drop-in can just add
distro-specific args.
For example
  /lib/systemd/system/nfs-mountd.service.d/local.conf
   [Service]
   EnvironmentFile=/etc/sysconfig/nfs
   ExecStart=
   ExecStart=/usr/sbin/rpc.mountd $RPCMOUNTDOPTS

Note the need for the empty assignment to remove existing definitions
first.

systemd: Relax dependencies of services

2015-03-19T15:44:16+00:00

Stop depending on basic.target in the daemons which still do;
i. e. add DefaultDependencies=no. This makes it possible to
run NFS during early boot, and helps if you e. g. have /var
on NFS. We don't require much else than local-fs.

systemd: Ensure RPC pipefs is mounted before rpc.idmapd starts

2015-01-23T15:35:32+00:00

rpc.idmapd aborts on start-up if RPC pipefs is not present.

Needed if GSS services are not used.

systemd: Bind rpc.idmapd to the nfs-server service

2015-01-15T10:41:16+00:00

Since rpc.idmapd is only used by the nfs server,
to do its id mapping, bind the rpc-idmapd service
to the nfs-server service so rpc.idmapd will
started and stopped with the server.

systemd units: create nfs-config.service as single location to process config.

2014-03-24T20:30:04+00:00

Instead of processing the config information into command lines every
time it might be needed, do it once in a separate service that other
services can Want.

systemd: add nfs-utils.service which can be used to restart everything.

2014-03-24T20:30:04+00:00

With this patch, systemctl restart nfs-utils will restart any
nfs-utils daemons that are currently running, whether there were
started via nfs-server.service, nfs-client.target, or directly by
systemctl.
