Re: stateless wants pxelinux.0

[Jason Powers <powers.jason@xxxxxxxxxxxxxxxxx>]

The pxelinux.cfg file isn't part of stateless specifically, it's more of 
a general "here's some boot-time parameters" file. We've been using LTSP 
 here for a while, and I know if you search that page or just google 
tftpboot +pxelinux you get a lot of docs referring to how the things are 
configured. I've seen man pages and such for it, but none are complete.

I'm trying to get the diskless version of staeless to run, because the 
LTSP local apps config is a nightmare, and I need the terminals' memory 
to handle the application being used. It has a terrible memory leak and 
I'd rather it drop one client than the whole server.

The present install of stateless is supposed to run a cron job every 
hour to manage all the pxe stuff, but it hasn't worked here yet. I'm 
starting this experiment over and running it off an nfs server to 
diskless clients, I'm going to try to install from the terminal directly 
to the NFS share and see if that works a little better, the "install it 
on a machine and then remove the hard drive" trick isn't getting it 
done, even with a clever-crafted pxelinux.cfg.

ps. my 'old' pxelinux.cfg/default file, which works for ltsp but not 
stateless. YMMV.

  kernel bzImage-2.4.26-ltsp-2
  append init=/linuxrc rw root=/dev/ram0 initrd=initrd-2.4.26-ltsp-2.gz
