Re: LTSP NFS

Hi,

One more thing about LTSP NFS : it's possible to use a dedicated server which does only NFS.

To that end, you need to configure the exports with specific options on the dedicated NFS server :

/etc/exports
```
/ltsp *(ro,no_root_squash,async,no_subtree_check)
```

Then, you can copy the LTSP client rootfs (/opt/ltsp/amd64) on your NFS server and configure PXE boot :

/var/lib/tftpboot/ltsp/amd64/pxelinux.cfg/default 
```
[...]
  LABEL Linux Ubuntu 18.04 NFS
  KERNEL vmlinuz
  APPEND ro initrd=initrd.img init=/sbin/init-ltsp root=/dev/nfs ip=dhcp boot=nfs nfsroot=<NFS_server_IP>:/ltsp
  IPAPPEND 3
[...]
```

However, my tests show much slower boot with NFS for now. It might not be a good idea to use NFS after all.

Thank you for the doc. My project with testing LTSP NFS is on standby for now. 

I'll let you know if I found anything interesting to note when I come back to it.

Thank you for the tip ! Good to know. 



I tested it with your instructions and with `unsquashfs` and it worked. 
I have described the NFS configration here: [ http://dashohoxha.fs.al/ltsp-scenarios/#org9be607e | http://dashohoxha.fs.al/ltsp-scenarios/#org9be607e ] 
Please let me know if I have missed anything that I should have mentioned.

You can also use 'unsquashfs` to uncompress a "chrootless" 
/opt/ltsp/amd64.img image into a /opt/ltsp/amd64 chroot, 
i.e. instead of using ltsp-build-client, to start the chroot with a 
snapshot of the server installation.
