1. binds are undone by unmount (described on the same manual page as bind, namely bind(1))

2. you can't kill another's process unless you are the owner of a terminal or cpu server
	and even then you need to change the mode of the process file before killing it.

		% ps
		forsyth           1    0:00   0:00      64K Wait     init
			...
		none            847    0:00   0:00    1284K Open     httpd
		forsyth         848    0:00   0:00      56K Read     ps
		%
		% echo kill >/proc/847/ctl
		/proc/847/ctl: rc: can't open
		% chmod 666 /proc/847/ctl
		% echo kill >/proc/847/ctl

3. i don't think tlssrv has been distributed yet

I used Plan9 for some month.

I have some questions for plan9.
Are there any web page FAQ for new users like this? I know Plan9 FAQ by FYWSS.

1. bind
Can I unbind directory?

For example
% cat /usr/jun/a/t
This is a
% cat /usr/jun/b/t
This is b
% bind /usr/jun/a /usr/jun/b
% ls /usr/jun/b
/usr/jun/b/t
% cat /usr/jun/b/t
This is a
%

In this case, how can I access to b's original t? or can I unbind 'a' from 'b'?

2. kill process
Can I kill other owner's process?

For example
% ip/httpd/httpd
% ps
...
none	157	0:00	0:00	1284K Open httpd
% kill httpd
% (No message)

How can I kill httpd?

3. Imap4 with SSL
In /bin/service.auth/tcp993, it execute "tlssrv". Where can I find it?
