This effectively removes the ability to create diskless NFS clients, following the rough process outlined at http://fedoraproject.org/wiki/StatelessLinux/CreateClientImage (using febootstrap in place of anaconda which no longer supports the --rootPath option).  Even if the code is not perfect yet, I would like to see the existing functionality remain in Fedora 15 and beyond.

Sure, we built an appliance, but then we threw it away and just used the supermin appliance :-)  The new way of doing it, where we don't build an appliance and throw it away, therefore makes a great deal more sense for us.

(I actually have some fixes I would like to contribute to pre-3.x febootstrap.)  The name "febootstrap" implies a Fedora variant of "debootstrap", and I just see this creating all kinds of confusion.

Rich,

I admit that I have not been involved with Fedora beyond submitting a 
few patches for some existing packages.  However based on my 
understanding of the Fedora project, I'm not following the rationale 
here, so please help me understand.

A brand new application (dubbed "febootstrap 3.x") was written entirely 
from scratch, in a different language from febootstrap (OCaml vs. bash), 
that does something quite different from febootstrap (it builds supermin 
appliances instead of chroots).  I think this would suggest that 
"febootstrap 3.x" should have to undergo the normal review process for a 
new Fedora package.  But instead, the existing "febootstrap" package 
which was already accepted into Fedora is basically being replaced with 
unreviewed code, which has removed the chroot-building functionality out 
of Fedora without any packaged alternative (again, please correct me if 
I am wrong).  The chroot-building functionality is necessary to perform 
diskless booting from NFS, which is a goal of the Stateless Linux 
project:  
http://citethisbook.net/Red_Hat_Introduction_to_Stateless_Linux.html

If you are looking for a new maintainer for febootstrap, I think that is 
one thing, but I would urge you not to actively remove functionality 
from Fedora that is currently being used without providing an 
alternative for it.

I particularly disagree with the notion of calling the chroot-building 
code "febootstrap2".  This implies that the supermin-building code 
supersedes the chroot-building code, which it does not.  I think there 
is value in both capabilities and they should both continue to be 
developed further and packaged natively in Fedora.  I repeat my earlier 
concern that the name "febootstrap" suggests "debootstrap for Fedora", 
which febootstrap 2.x is, but "febootstrap 3.x" is definitely not.  I 
think the supermin-building code needs to be called something else and 
packaged in such a way that it does not interfering with febootstrap.

I am curious if there are other febootstrap users who share my concerns, 
and what thoughts Fedora QA has concerning this?

Thanks,

David
