They work pretty well as thins. Would you expect them to work
any better as fat clients?


I built the fat client image with these instructions:
https://help.ubuntu.com/community/UbuntuLTSP/FatClients

But I'm not sure how to have just those more powerful systems
boot from the new image. (I don't want to move the fat image
to /opt/ltsp, I want to leave it at /opt/ltsp-fat)

So, am I modifying /etc/ltsp/dhcpd.conf ?
Or is it something in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/ ?

Any hints appreciated.

If the stronger machines have more RAM, you could use FAT_RAM_THRESHOLD to specify which clients should run as fat and which thin. So in your lts.conf you could have something like:


"""
[default]

  FAT_RAM_THRESHOLD=512

[00:A1:08:11:F2:C8]

   LTSP_FATCLIENT=false
"""

In the above example, machiens above 512MB or RAM will start a fat client session. A machine with more than 512MB of RAM can be set to use a thin client session by using the LTSP_FATCLIENT directive.
