I do this for a server in my LAN. I use DHCP+TFTP to boot grub over the network via PXE, and then grub boots the Kernel
with the root pointing to a NFS share:
Doing this makes managing that installation much easier. It’s just a directory that lives on the Main Server.
I don’t even need to boot the other Server to update the software in it, chroot is enough. And I don’t even have to worry about doing separate backups,
because I already back up the Main Server’s Storage regularly.
