After asking in this thread, I'd like to volunteer for maintaining openSuSE support of i-MSCP.
You can find the current status of my work in my github repo:
I've abstracted some functions and implemented distro specific variants of them (e.g. enabling services, installing packages). Additionally, I've separated the non-Debian specific configuration files into a common directory and provided specific files for openSuSE.
I tested most of the functionality already on openSuSE 12.1beta and it mostly works great so far, but a lot of additional testing is of course necessary, especially on older SuSE versions. I didn't do any SSL or IPv6 testing either.
If someone wants to test it, you should first add the repositories "devel:languages:perl" and "Apache:Modules", as this is not yet done automatically.
