Boyer: At the playground

Fedora kernel team member Josh Boyer, writes about a Fedora kernel-playground Copr (Cool Other Project Repository) on his blog. The idea is to provide an unsupported kernel that has some new features for those who want to help develop and test them. "OK, now that we have that out of the way, let's talk about what is actually in kernel-playground. At the moment there are two additions on top of the standard rawhide kernel; overlayfs (v22) and kdbus. Overlayfs is one of the top competing "union" filesystems out there, and has actually been posted for review for the past few releases. It has the best chance of landing upstream sometime this decade, and there has been interest in it for quite a while. I believe things like Docker would also be able to make use of it as a backend. I'll track upstream submissions and update accordingly. kdbus is of course the thing that Lennart Poettering and Kay Sievers have been talking about at various conferences for a while now. It is the in-kernel d-bus replacement. It has not been submitted for upstream review yet, but systemd already has support for it and things seem to be progressing well there."
