Public bug reported:
/etc/default/nfs-kernel-server invites you to pass additional arguments
to rpc.svcgssd by populating RPCSVCGSSDOPTS, e.g.:
RPCSVCGSSDOPTS="-n"
/lib/systemd/system/rpc-svcgssd.service passes additional arguments to
rpc.svcgssd from the variable $SVCGSSDARGS with the environment file set
as /run/sysconfig/nfs-utils. The content of the environment file is:
PIPEFS_MOUNTPOINT=/run/rpc_pipefs
RPCNFSDARGS=" 12"
RPCMOUNTDARGS="--manage-gids --no-nfs-version 3 --no-nfs-version 2"
STATDARGS=""
RPCSVCGSSDARGS="-n"
As -n is not passed to rpc.svcgssd it does not start as my keytab does
not contain an nfs/<fqdn> principal:
