Hi Wolfgang,
I?m using the manual above to setup a server completely offline without
creating the combined LTSP image but just the one for thin clients. I?m
skipping the later steps regarding building chroot for diskless
workstations altogether.
The server is created apparently without issues, which is good news!
As expected the image is significantly smaller with 336mb. However, my
thin clients can boot on both subnets.
I don?t get a black screen. The display shows a few usual [ok] messages
and then booting hangs without throwing an error message.
Kind regards,
Roman
