There's some interest from people doing vfs maintenance work (as it has potential to save their work) and it is actually a reasonable task for someone wanting to get acquainted with filesystem development work. So I think there are chances of some progress. For example there was some interest in doing this for minix. Of course we'll be sure only when it happens :) > Alternatively someone could implement a "VFS emulator" library. But > keeping that in sync with the kernel, together with all the old fs > would be an even greater burden... Full VFS emulator would be too much I think. Maybe some helper library to ease some tasks would be useful but I think time for comming up with libraries is when someone commits to actually doing some conversion. Honza -- Jan Kara SUSE Labs, CR
