[9fans] online updates now available

["Russ Cox" <rsc@plan9.bell-labs.com>]

We have set up a Plan 9 file server to distribute
updates using the replica(1) tools.  To create an
account on the server, you must go to the web page

http://plan9.bell-labs.com/plan9dist/newaccount.html

and answer The Questions one final time.  Once you
have created an account, you will be presented with
instructions for updating your Plan 9 installation.

To update your kfs system, run the following script (if you
set up a non-kfs file server, you'll have to edit to suit):

	cat >/tmp/network <<'!'
	#!/bin/rc

	s=/n/dist/dist/replica
	serverroot=/n/dist
	serverlog=$s/plan9.log
	serverproto=$s/plan9.proto
	fn servermount {
		srv tcp!sources.cs.bell-labs.com sources /n/sources
		bind /n/sources/plan9 /n/dist
	}
	fn serverupdate { status='' }

	fn clientmount { 9fs kfs }
	c=/n/kfs/dist/replica
	clientroot=/n/kfs
	clientdb=$c/client/plan9.db
	clientexclude=(dist/replica/client)
	clientlog=$c/client/plan9.log

	applyopt=(-u -T$c/client/plan9.time)
	!
	chmod +x /tmp/network

	cat >>/net/ndb <<'!'
	auth=sources.cs.bell-labs.com authdom=outside.plan9.bell-labs.com
	!

	echo -n refresh >/net/cs

	disk/kfscmd allow
	replica/pull -v /tmp/network

After running this, you'll be able to use

	disk/kfscmd allow
	replica/pull -v /dist/replica/network

to retrieve future updates.

See replica(1) for more information.

If you have customized /lib/ndb/local,
the update will not overwrite it.  Instead,
add the following line:

	auth=sources.cs.bell-labs.com authdom=outside.plan9.bell-labs.com

The additional packages are also available
on the same server.  After updating, you can do

	9fs sources
	ls -l /n/sources/extra

to see them.

Enjoy.
