As an added feature, I hope you want to have control who wrote a file.
AFS seems to do this in a good way, but Kerberos is a constant annoyance
to it. I do have machines that generate simulation data and have to work
for weeks. If I like to do this with the current OpenAFS setup, I'll
have to log in once a day and refresh the damn Kerberos token :-(.
You can have longer timed tickets and tokens. You can save tickets in
keytabs. If your hosts have keytabs, you can use them to generate
tickets from.
You can have system:anyuser write if you want to mimic NFS ;)
And you can create pts groups based on IP-addresses and give such a
group permissions in the ACL. That's less horrible than giving
system:anyuser write access. But after you have done this you have to
wait quite a while until the fileserver has re-evaluated those IP-groups
(typically 2 hours) before they work.
