Oh, that's nice :) Have you tried mounting the resulting nodes? I'm sorry it took me some time to give feedback, part of is it that I wanted to let the idea float a bit before answer. One thing that would be really needed for efficiency is to implement netfs_file_get_storage_info, so that libstore would be able to get the underlying storage information, and directly get data from there rather than partfs having to pass data with io_read/write. I'm then wondering how this would fit in the "grand scheme". Our current approach, /dev/hd0s* being always there, is indeed not really good because it doesn't easily tell the user which partitions are actually there. We used to have to have this because partitions used to be handled by the kernel, and then we have moved to storerio+parted-supported partitions, which brings much more flexibility. Perhaps we could use settrans -c /dev/hd0s /hurd/partfs /dev/hd0 and then we'd have /dev/hd0s/1, which is almost like before, but allows the entries to be dynamic. Actually, we could even have some settrans -c /dev/hd /hurd/probedisk hd and then we'd have /dev/hd/0, and we could have /dev/hd/0s being partfs, so we'd eventually have /dev/hd/0s/1 But I'm also thinking that perhaps it could be integrated more with storeio, i.e. /dev/hd0 can as well also act as a directory with partfs behavior, so you could have /dev/hd0/1 and with the probedisk translator, you could have /dev/hd/0/1 What do people think about it?
