login requirements?

[Howard Jones]

Hi,

I'm building myself a DoM-booting FreeBSD 5.1 system, to replace some 
aging Wyse WinTerms that we have around the office. I did this 
successfully a couple of years ago with 4.5 with no trouble, so I know 
it's basically good to go.

I'm doing it by building up the minimum system to run the binaries I 
need (sshd, ssh, X, rdesktop). It's all working fine except for login. 
Does anyone know what the minimum file set for login actually is? So 
far I've copied libpam.so, login itself, all the pam_*.so modules, 
login.conf and the pam.d/* files.

What I get is a message about "chunk already freed" whenever I attempt 
to login, either on console, or over telnet/ssh. I assume that 
something else is required and missing, but I can't figure out what - 
any suggestions?

Thanks in advance,

Howard

[side question - the next stage after this is to try a pxeboot-based 
version. I can't find much info about how to use a built-in md device 
in a 5.x kernel though. Is this possible? I'd rather like to avoid 
running an NFS server if I can...]
