Gentoo nfs-utils package still doesn't include a systemd unit file, |
32 |
really? With a perfunctory look at |
33 |
/usr/portage/net-fs/nfs-utils/files, I see several *.service files. I |
34 |
highly recommend using the unit files provided by the Gentoo devs. |

I have no idea; I haven't set an NFS server in years. However, most |
74 |
target units usually are kinda "virtuals"; the bring other units up. |

79 |
Something should define RPCNFSDARGS; perhaps a drop-in? |

Walt, from time to time run "systemd-delta" and see what |
125 |
configurations of yours differ from upstream (either systemd and/or |
126 |
Gentoo). I think you should be using nfs-utils' included unit files. |
127 |
|
128 |
Regards. |
