[nfs-utils PATCH v2 0/4] add systemd generator for the rpc_pipefs mountpoint

[Scott Mayhew <smayhew@redhat.com>]

These patches aim to make it a little easier to change the mountpoint.
Right now if you change the pipefs-directory in /etc/nfs.conf, you still
need to manually override the dependencies in the systemd unit files in
order for the change to actually work.

The first patch moves rpc.idmapd's (mostly) undocumented
pipefs-directory from /etc/idmapd.conf to a newly created [global]
section in /etc/nfs.conf.

The second patch makes rpc.gssd read its pipefs-directory setting from
the [global] section of /etc/nfs.conf instead of the [gssd] section.

The third patch allows blkmapd to read its pipefs-directory setting from
the [global] section of /etc/nfs.conf as well (previously it was
hard-coded).

The final patch adds a systemd generator that reads the
pipefs-directory configuration from /etc/nfs.conf, and if it differs
from the default it will automatically create a systemd mount unit
file for the pipefs mountpoint and it will override the dependencies on
the pipefs mountpoint via the rpc_pipefs.target unit file.

Scott Mayhew (4):
  idmapd: move the pipefs-directory config option to nfs.conf
  gssd: move the pipefs-directory setting to the nfs.conf global section
  blkmapd:  allow the rpc_pipefs mountpoint to be overridden
  systemd: add a generator for the rpc_pipefs mountpoint
