Re: [Ltsp-discuss] Can I build an Ubuntu Xenial chroot on a Debian Jessie LTSP server?

I finally came back to revisit this. ldm was already installed in the chroot, but the client still only boots as a thin client. These servers normally present clients configured using the ltsp-pnp method. I was trying to also add special purpose clients for occasional programming

So I successfully built an Ubuntu 16.04 fat-client on a Debian Jessie server. Rather than installing from jessie-backports, I pinned the ltsp packages to the testing repository instead. The client only boots as a thin client even with FAT_CLIENT=True in the lts.conf file. Is a fat-client
