---++ MPU Meeting Tuesday 5th August 2014

---+++ Virtual DICE

Chris has written the [[https://wiki.inf.ed.ac.uk/DICE/FinalProjectReport239][final report]], Alastair and Stephen will review.

---+++ LCFG Client Refactoring

Stalled.

---+++ systemd

The componenth has been changed so that it is possible to link to services which are created within =/etc/systemd=, this makes it possible to set the default target to be something which we have created.

The component also needs to be able to set the "preset" state for services. This means that package scripts will enable or disable the service as required at install time.

---+++ SL7 LCFG port

Stephen has finished the installer support in the grub2 component.

Alastair has discovered that the client component is failing to get the addresses for the servers. Also LDAP lookups do not always work. When LCFG is installed onto a natively-installed RHEL7 machine we do not see the same problem, it's not clear what is causing the problems on LCFG-installed machines. Removing DNS from the equation appears to resolve the issue (i.e. using IP addresses instead of names). It also appears that an LCFG-managed machine using DHCP is fine. The problems could be related to waiting for the network to be completely functional, there is a difference between =network= and =network-online= systemd targets. Is it just taking too long for the network card to auto-negotiate with the switch?

It appears that the =ifcfg-eth= network scripts are parsed by a networkmanager plugin which converts them into the networkmanager configuration format. It's unclear just how much of the options in the old scripts are supported, we probably need a new component to generate native networkmanager config files. We can handle the network configuration needed for standard desktops with the current LCFG network component.

We need to set the fully-qualified hostname using the new systemd tool - =hostnamectl= - so that everything works correctly. There appears to now be two types of hostnames, _static_ and _dynamic_.

We need to fix the updaterpms performance issues related to the "flagging" stage.

Should we run nscd when not using a local bind daemon?

The LCFG mail component has now been ported to EL7 and appears to work.

Chris has generated an LCFG desktop package list based on the Gnome package group. He will look at the various graphical components (e.g. lcfg-kdm) which need porting.


---+++ Miscellaneous Development

None this week.

---+++ Operational

   $ ordershost : The ordershost has moved to _steen_

   $ MPU reboots : We each need to choose some MPU servers to reboot.

   $ EPEL 6 : We have run out of space for new EPEL 6 packages. Stephen will come up with a plan to resolve the issue. This probably needs coordinating with Kenny.

---+++ This Week
