Hi folks,
I did a new installation this morning.
None of the clients is booting and I get an error that a file could not be found. I had a closer look at the following file: /srv/tftp/ltsp/ltsp.ipxe
At the end of the file I found the following two entries:
initrd /ltsp/ltsp.img
initrd /ltsp/${img}/initrd.img
I commented the first entry, which fixed the issue.
Kind regards,
Roman
