Subject: PXE is proprietary - what the heck is it doing as the default
LTS install in Edubuntu or Ubuntu?
Date: Fri, 2 Jun 2006 12:25:36 -0700 (PDT)
Hi Jane,
Congrats on 6.06...
Only it is TOO BAD that you are using PXE..., instead of the LTSP
supported and recommended ETHERBOOT, for LTS clients to talk to the LTS
Edubuntu Server!
Here are some quotes from Disklessworkstations tech support as I tried
to get them to support Edubuntu with their bootable network cards.
"We do not provide network cards with PXE only Etherboot. PXE is
proprietary and requires a license to sell".
""The method describing how to create a
Etherboot'able kernel would be run every time there is a Ubuntu
kernelupdate to keep the kernel current".
So - when are you going to release a default kernel fix to Edubuntu and
get rid of the proprietary PXE stuff? Soon I hope.
It is my understanding that cooperation broke down between the *buntu
folks doing LTS and the LTSP teams... and that the LTSP teams are saying
that the *buntu LTS folks have taken some wrong turns and it seems that
one of them (by not listening to their LTSP elders) is the default
support of PXE instead of Etherboot. It's no wonder that their LTS
stuff only will support PIIs and 48 MB RAM as a suggested client! Why
didn't they do what the LTSP.org folks suggested?
Best regards,
Camp Catherine Capers
