Re: LTSP NFS

Turns out I was missing a few things. First, NFS is not compatible with chrootless which I was using. 

To turn my NDB installation into an NFS installation, I needed : 

``` 
sudo apt install nfs-kernel-server 
sudo ltsp-config nfs 
sudo systemctl restart nfs-server 
sudo ltsp-build-client --purge-chroot --mount-package-cache # creates a chrooted environment in /opt/ltsp/amd64 
sudo ltsp-chroot -m apt install gnome-session # I use gnome as desktop environment 
``` 

And also had to modify /var/lib/tftpboot/ltsp/amd64/pxelinux.cfg/ltsp to default to ltsp-NFS (there is probably a more conventional way to do this). 

You don't need `ltsp-build-image` if you're not using NBD. This is a advantage for me as building the image can take quite some time with the 100+ packages I install.

Hi, 

I wanted to try NFS instead of NBD on a working LTSP setup with Ubuntu 18.04. Is NFS still supported ? 

I did `apt install nfs-kernel-server && ltsp-config nfs` and changed boot to ltsp-NFS instead of ltsp-NBD. The client start booting but ends in a loop : 

``` 
Begin: Retrying nfs mount ... no search or nameservers found in /run/net-ens3.conf /run/net-ens3.conf /run/net6-*.conf 
mount call failed - server replied no such file or directory 
done. 
Begin: Retrying nfs mount ... 
``` 

I have the same error "no search or nameservers found in /run/net-ens3.conf /run/net-ens3.conf /run/net6-*.conf" while booting with NBD, but the client continue and boots normally. 

I would like to confirm I did everything correctly before filing a bug.

P.S. I know NBD should perform better than NFS but in my case, I have an Virtual Storage Infrastructure with a 2GB bandwith supporting NFS / CIFS / iSCSI only. My LTSP server has 1GB bandwith only.
