Package: schroot Version: 1.4.16-1 Severity: wishlist Since the kernels in experimental do not ship aufs, it would be great if you could add support for unionfs-fuse as well. I have the following patch applied in my setup.d script to automatically fall back to unionfs-fuse if the native solution is not available, as that allows me to build fast when running under 2.6.32 and use the slower FUSE-based way when running newer kernels.
