[...] I'm compiling this patch on my test system right now. Another issue is userland support for unionfs, e.g. in fstat, as described on this page: http://c0mplx.org/src/fstat-unionfs-patch/ Do you plan to analyse/investigate this topic ? There's another topic if one uses unionfs in jail() setups: How to backup the files, and only those files that a different from the base ? If I traverse a mounted unionfs, how do I know where data is coming from, the lower mount or the higher mount ? If I can't tell the difference, I'll backup quite a lot of stuff multiple times. I've experimented a little and found no easy way to tell lower from upper unless I open the file (which sounds expensive). Have a look at http://c0mplx.org/src/isunionfs.c -- does this sound like a way to go ? -- pi_at_c0mplx.org +49 171 3101372 13 years to go !Received on Wed Sep 19 2007 - 00:16:45 UTC
