[Bug 1971935] Re: Invalid pipefs-directory prevents rpc-gssd.service from starting

[Andreas Hasenack]

Can you elaborate a bit on your scenario? Since you are trying to start
gssd, I assume you have a kerberos environment, and the server has a
keytab in /etc/krb5.keytab (which is a condition for the gssd service to
start).

In my tests, I also usually reboot the server after installing all the
nfs and kerberos-client bits, exactly because the services have
dependencies between them and all these conditions on files.

I'll check the incorrect path you spotted, see if it's supposed to be
the same thing indeed.

Title:
  Invalid pipefs-directory prevents rpc-gssd.service from starting

Status in nfs-utils package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 22.04 Server
  Package version: 1:2.6.1-1ubuntu1

  Package nfs-common/nfs-utils provides /etc/nfs.conf and /lib/systemd/system/rpc-gssd.service.
  /etc/nfs.conf (and seems to be copied from /usr/share/nfs-common/conffiles/nfs.conf) has the configuration:
  ...
  [general]
  pipefs-directory=/run/rpc_pipefs
  ...

  When attempting to start rpc-gssd it gives the following error:
  ...
  ERROR: opendir(/run/rpc_pipefs) failed: No such file or directory
  ...

  There is a systemd unit called var-lib-nfs-rpc_pipefs.mount which
  mounts this directory as /var/lib/nfs/rpc_pipefs. However this does
  not match with the configuration in nfs.conf

  It's worth mentioning that sometimes it seems a systemd unit is
  generated (run-rpc_pipefs.mount) which ensures /run/rpc_pipefs is
  created and everything works as expected. Seems to be random.
