build (user/groupadd issue), see bug #53269
- include nfsroot_stage4-slim.spec in this commit
- remove threads from the openmpi USE flags (USE flag changed to mpi-threads)

Re-arrange nfs exportfs generation into function calls (cleaner and more versatile)

USER_AUTOMOUNTHOME=no
- git version of diradm is corrected but not in the portage tree so I created a patch for local usage
NOTE: Another bug remains. The UID auto-incrementor doesn't seem to work (BUG)

- cluster-setup:
*$PBS_SERVER_HOME/server_priv/nodes is now generated by the ebuild
*/etc/init.d/pbs_sched start added
- nfsroot_setup.sh:
* /etc/conf.d/net was not generated correctly, vars were interpreted during the config file generation and no put into the config file
- beowulf-head-0.1.ebuild:
* There were still some nonfsv4 incorrect USE flags
- node-manager:
* logic rework and some test corrections
* less implcit mangling of $@ on function calls
- torque-add:
* we need to restart pbs_server on modifying $PBS_SERVER_HOME/server_priv/nodes
** this is horrible but the only reliable way to add nodes as per http://www.clusterresources.com/wiki/doku.php?id=torque:3.1_adding_nodes

- gvim
- cscope
NOTE:
The livecd won't build because of (snapshot change) Bug 233337 and probably others...

- server USE flag was mnissing in the livecd specs
- added pbs_mom to nfsroot spec
NOTE:
code is not "functionnal", node-manager is in constant flux as I am figuring out dhcpcd and dnsmasq exhanges of userclass information, which we will use as a means to send the cpu count to the server for the config gilse

circumbstances from within the dnsmasq script callback.
- esentially add a default number of procs/node in the config file

- added passwordless SSH for root to nodes
- added some FAQs and documentation
- quick update of the HOWTOs
- switch to snapshot 20080816
- added torque (PBS) and underlying support modules
- added a few config variables to scripts to ease future changes
- created openrc-0.2.5-r1 to ease the NFSROOT howto procedure
+ (don't have to unpack and repack the snapshot for running ebuild * digest)
* corrected invalide use of non existant functions.sh in nfsroot_setup.sh
beowulf-head-0.1.ebuild:
* Added the modules infrastructure to be called by dnsmasq's script callback interface
* provided examples are for torque and c3.
-- C3's configuration file is valid but doesn't seem to work (might be a python issue)
-- torque is _still_ work in progress:
+ some of the setup seems to be incomplete (in the ebuild)
+ the profile switch was to get a better chance at a working installation (2.3.3)
- Science overlay was added to pull in the modularized version of openmpi
Since USE=pbs in the specs, openmpi requires Torque but Torque also require kernel (stage2). Torque is currently being built twise, once minimal for openmpi, then with kernel features in the stage2. Commenting out pbs and torque in stage2 reverts the build to a simple cluster without the whole PBS infrastructure...but it works ;)

livecd (minimal)
ssentially genkernel's --no-splash options doesn't works.

- node-manager : this is the script called by dnsmasq (see dhcp-script).
- *-add and *-del files are "modules" which are called by node-manager on addition and deletion of nodes as per dnsmasq.

them in the beowulf-head ebuild
- We can't use this approach for the mooment since the files need to be accessible from the livecd at configuration time and the portage tree isn't in the livecd...

Addition of DNS tools for debugging name resolution
Correction and cleanup of some scripts
Name resolution now works correctly/automatically. No static entries required, host name resolution is entirely managed by dnsmasq.

- We can't define multiple IP addresses for a single hostname and since a Beowulf Head node is multi-homed (by our current definition) we use rootserver, which is sent out by DHCP and parsed/set by stateless.sh. It is horrible but it works, as long as the DHCP server sends out the correct info.
Fix:
- authmaster keyword was blocking out code that it shouldn't
Misc:
- cleaned out useless code/comments

AuFS module usage imlpies we're switching back to mainstream gentoo-sources
nonfs4 already existed and is used by nfs-utils...we'll tag along

Corrected many OpenRC bootup sequences and quirks
--Thanks to Uber(lord) (Roy Maples) for quick fixes
--NFSroot system now boots up quickly
**There are still a few error messages on shutdown that will be adressed in later versions of OpenRC

- sshd keys generated in catalyst run
- runlevel scripts cleaned out for a smoother boot
* shutdown and reboots are still unclean, OpenRC needs to ignore useless tasks (given it's an ro ROOT)
* still need to resolve the "Caching service dependencies" at boot time (very slow)
Updated HOWTOs for merging nfsroot and livecd into a single ISO, currently incomplete:
- Added AUFS to livecd, needs to be configured to mount nfsroot as rw for the beaowulf-head config script to function
- Once AUFS is functionnal, we can start testing the booting of nodes off the livecd!
** Vmware is being used and is causing some problems:
-- e1000 emulation is so good we're getting kernel module problems (irq related...is it the module or VMware...)
-- found out how to disable DHCP on the local virtual net (thanks go to Demosthenes on gentoo-server): simply delete the files in /etc/vmware/vmnet1/dhcpd/ and the VMWare dhcpd won't start.
