MPU Meeting 12th April 2017

LCFG Client Refactoring

The context support is now finished and documented. Stephen has moved onto the packages support which is now well on the way to completion.

Chris has verified that iFriend access works fine for him. Stephen suggested opening up the test service to http/https access on edlan and then posting to the lcfg-discuss mailing list to ask for volunteers to check the service.

Final report
Stephen has created a skeleton final report page on the wiki.

Miscellaneous Development

systemd component
Alastair has reworked how the systemd component enables services so that links are used instead of empty files. This fixes a number of issues. It is now possible to have a local console along with serial console on servers. He will put it onto develop machines for a couple of weeks to ensure it is working correctly.

systemd final target
Stephen now has a working final target which services can be hooked into. We can use this to disable kernel module loading at the best time.

The default release for SL7 develop machines is now 7.3. A few machines have problems because they were on the stable release but had the DICE_TRY_SL73 macro defined. When the DICE_STICK_WITH_SL72 was also added they got downgraded which broke some of them. Stephen will modify the procedures (and the script) so that this doesn't happen again.

Some of the systemd resources for the resolvconf component were still hanging around. Stephen modified the lcfg/options/dns.h header to do a better job.

server dns
Stephen has modified the list of nameservers in resolv.conf for SL7 servers on the develop release so that only localhost is listed. This brings them into line with the SL6 release. If there are no problems then he will extend this to all SL7 servers soon.


The general access SSH server has moved to bruegel, the old server schiff still needs to be turned off.

LCFG servers
We need to get muro running as a slave so we can compare with the new LCFG slaves.

openafs build service
This has moved to juice and budapest is turned off awaiting junking.
