Release: ltsp-5.1.21 for Fedora 9

[Warren Togami]

I just pushed ltsp-5.1.21 and ldm-2.0.12 to my temporary repo.  It 
should hit Fedora updates later this week.  This is likely going to be 
the basis of the Fedora Live LTSP Server Beta2.  (I am still working on 
the branding issue.)

This update contains many bug fixes and additional features over 
ltsp-5.1.15 currently in Fedora 9 updates.

* NBI and ELF netboot (generally Etherboot) is now fully supported. 
Images are generated automatically, and the new dhcpd.conf should 
automatically serve the right image to a client.  You may need to 
install your /opt/ltsp/i386 chroot fresh with ltsp-build-client and 
update your /etc/ltsp/dhcpd.conf from ltsp-server to benefit from this 
new support.
* NBD swap by default actually works now!  (Except it is disabled if the 
server is running from a Live image in order to conserve memory.)
* John Ellson fixed a few bugs to get x86_64 clients installable and 
working.  Still requires a bit manual configuration but it should work now.
* Old kernels and images are safely clenaed from the tftpboot directory 
if they are no longer installed in the client chroots.
* (ADVANCED USERS: Most users don't really need this.)
NBD root is now supported as an option.  Default is still NFS root. 
Update your dhcpd.conf to the latest version from ltsp-server.  It 
contains example syntax to switch your clients from NFS root to NBD 
root.  ltsp-update-image will generate a NBD root image from 
/opt/ltsp/i386 and drop it into /opt/ltsp/images/i386.img.  Note: This 
requires the patched mkinitrd also in the k12linux-temporary repo to be 
installed in the client chroot.  This will go into Fedora 10 and Fedora 
9 updates in a few weeks.  I really need to write documentation for this 
on the Wiki.
* (ADVANCED USERS: Tech preview status)
Working Local Apps support, requires openssh-server-5.1 on the 
ltsp-server side, available in Fedora updates-testing.  I will write up 
some docs for this on the Wiki soon.

I tested all this pretty vigorously, but please let me know if you run 
into any problems.
