That sound like fun. How does it work? This is the server
which df would used when invoked with no filesystem as an
argument? Is there a program which would do something similar
for some other service? What should I have read before asking
you these questions?
Thinking aloud:
Let's add an optional call in mount (is mount the right
place?) a call to
register_mount_point(host, remote_host, remote_mnt_pt, local_mnt_pt)
(or some such).
I guess that register_mount_point() gets defined in a hurd
library somewhere. What does it do? As I understand it, alice
and bob (as well as root) can be running df servers too. How
does register_mount_point know to register with those too?
How does the multicomputeriness of the Hurd fit in? Each
computer should have a df server? Or there is one central df
server to which df requests (register_me!, what_ya_got?) are
made from our Hurd cluster?
What sort of database would be appropriate for a df server?
A PostgresSQL interface or just a list of lists (that Guile
could handle). Would Guild be an appropriate language with
which to implement a df server? It seems lightweight, so
perhaps the answer is "no"...
Yours ignorantly,
Paul.
