SSL is implemented by devssl. It's extremely
obsolete by now, and is not used anywhere but
cpu, import, and oexportfs.
This change strips out the devssl bits, but
does not (yet) remove the code from libsec.
exportfs -d logs 9p traffic to /tmp/exportdb.
-f allows writing to a different file.
exportfs silently continues if it doesn't have
permissions to create or write to /tmp/exportdb.
These are poor behaviors.
A better default is to write to stderr, since it
is 9P debug info that is better immediately printed,
and not user info that is better handled by syslog().
As a result, -f is obsolete and thus removed.
Redirect responsibility is now on rc.
As a side effect, rc will fail if it doesn't
have permissions to write.
exportfs(4) is updated to reflect all changes
and with a better Synopsis.
oexportfs is changed to match exportfs.
oexportfs(4) is updated to reflect all changes.
The Synopsis is not changed due to the number of flags.
Removed -f from iostats.
iostats(4) is updated to reflect all changes.
---
The initial protocol handling in exportfs for
cpu and import services is a huge mess.
Saparate the code out into its own program with
its own oexportfs(4) manpage.
