Two sambas, one machine? How about pid files?

[eirvine]

Hi all :)
 
I want to move over to encrypted passwords so I can support
domain logons for NT SP5 machines. While I move over, I
still want to keep my support for the plaintext machines
up and running for a while.

I've had domain logons for Win9x machines with plaintext 
passwords for several years.

I've got a smbpasswd file happening, aliasing on my ethernet
card happening, and two versions of a smb.conf file. Different
interfaces, domains, spool files etc for each.

The idea is that I fire up two versions each of smbd and nmbd, 
right? One is pointed to the first smb.conf file, the other the second.
Yes? 
 
When I tried this, the second versions of smbd and nmbd
refused to start, because /var/run/smbd.pid and /var/run/nmbd.pid
were already there. I can't find an option to point the pid files
elsewhere. 
 
Am I missing something? Or do I have to hack the source and compile a 
second version of samba binaries?
 
Ta very much
Eddie.
