I welcome any improvements such as this. In the mean time, I could see
some purpose of running a fileserver on a mobile device if it stays in
one place for a while. This might be useful for conferences or local
gatherings of people and demonstrating openafs, but probably not for
full-time production data.
What are the plans for mobile fileservers, if any? Are we assuming
stable & static cell/DB servers or more ad-hoc models? With an ad-hoc
model how would you decide to trust the server when there is no
authoritative DNS available? Is there a plan for some type of PKI-like
model where a server can prove it's identity when it's address changes
and the cell servers aren't static or aren't available.
