This year Calamares is participating in Google's Summer of Code. While Calamares doesn't live under the KDE umbrella -- for political reasons, basically, to emplasize that it is a desktop-agnostic system installer -- it has a great deal of KDE DNA inside. The maintainers (that's Teo, then myself) have been KDE people, some of the technology is definitely KDE (KPMCore in particular). So we're happy to be participating under the KDE umbrella in a mixed KPMCore / Calamares role.
Andrius (KPMCore) and myself (Calamares) will be working with our student Caio Jordão de Lima Carvalho on a list of advanced partitioning scheme improvements. With this, we'll make KPMCore a more powerful library for dealing with complicated partitioning schemes, and Calamares a more powerful installer. The "advanced" schemes here are all based around LVM (Linux Volume Manager) which is something I've been dreading having to deal with -- so I'm really happy Caio will.
He's pushed stuff to KPMCore before, and his first pull request to Calamares arrived this week, so I feel we're off to a good start. Look for more on the Calamares site.
