[et-mgmt-tools] Cobbler WebUI and Multiple NICs (checked in)

[Michael DeHaan]

Web UI update...

So, the Cobbler/koan 0.6.3 as a release is looking like it will address 
primarily Web UI features (and of course multiple NICs).  Future 
releases will
not be so Web-UI centric, so if you aren't seeing your favorite RFE's 
committed ... they'll be coming soon enough.

For those interested in the WebUI, however, I've committed some newness 
that should be useful and interesting.

Namely, multiple NIC editing is now in the Web UI (thanks to Máirín 
Duffy for lots of DHTML help) and should make infinitely more sense than 
trying to pass dozens of arguments on the command line to configure 4 or 
8 different NICs.   Each NIC is shown seperately and can be 
expanded/collapsed as needed.   There's also a button to remove an 
interface if you've added one too many.   You can also edit virtual 
bridge settings for each NIC and get to the virtual CPU setting.

A couple of other features I'd like to get into this release are 
pagination for the "list" pages, which should help for when there are an 
extremely large number of systems (as in thousands) in the Cobbler DB.   
Database-backing (or something faster than  YAML) as an option will 
probably come in a later release as all of the above changes are enough 
for now.  

As an aside, someone has also asked for "cobbler sync" to get triggers 
(just like the "add" and "remove" commands -- 
https://hosted.fedoraproject.org/projects/cobbler/wiki/CobblerTriggers ) 
and I'm planning on including this in 0.6.3 as well.   This means that 
we'll move service restarts (DHCP, ISC) out into triggers, ship those 
triggers by default, and make configuration settings for whether or not 
they should be run.   This is the beginning of making the sync code more 
abstracted and the core a bit lighter weight.   Admins can then be able 
to write their own hooks, such as using the cobbler interface to manage 
DHCP files which are then rsync'd and applied to a remote system -- 
seperating cobbler and the DHCP server, or possibly using cobbler to 
configure multiple DHCP servers (we'll see where this goes).

If you're interested in the WebUI, everything has been uploaded to git, 
and installation instructions haven't changed.   Feedback welcome!

As I've said before, the Web UI is all generated from Cheetah templates, 
so if folks are interested in improving it, you shouldn't find it all 
that different than editing kickstarts :)
