We'd like to have this functionality available for use in lxd, and I'm interesetd in helping with development (or picking up development if it's stalled). To start, is anyone still working on shiftfs or similar functionality? I haven't found it in any git tree on kernel.org, and as far as mailing list activity the last submission I can find is [1]. Is there anything newer than this? Based on past mailing list discussions, it seems like there was still debate as to whether this feature should be an overlay filesystem or something supported at the vfs level. Was this ever resolved? Thanks, Seth [1] http://lkml.kernel.org/r/1487638025.2337.49.camel@HansenPartnership.com
