      Sorry if this is a stupid question, but I don't understand the
      mounting of file systems.
      I've unslung (6.8 beta) to disk 1. Connecting only disk 1 gives this:
      /dev/sdb1 6528 6344 184 97% /initrd
      /dev/sdb1 480482192 265627976 209972788 56% /
      /dev/sdb1 480482192 265627976 209972788 56% /share/hdd/data
      /dev/sdb2 116661 4179 111278 4% /share/hdd/conf
      If I connect disk 2 as well, I get this result:
      rootfs 480482192 265627972 209972792 56% /
      /dev/sdb1 6528 6344 184 97% /initrd
      /dev/sdb1 480482192 265627972 209972792 56% /
      /dev/sda1 480482192 311859904 163740860 66% /share/flash/data
      /dev/sdb1 480482192 265627972 209972792 56% /share/hdd/data
      /dev/sdb2 116661 4179 111278 4% /share/hdd/conf
      /dev/sdb2 116661 4179 111278 4% /share/flash/conf
      Notice that /share/hdd/conf and /share/flash/conf are both mounted to
      the same file system on disk 1. Is this normal, or should I worry
      about /share/flash/conf not pointing to disk 2?

      Thanks, Frank

        That is correct, actually. But it is strange, and this behavior by the Linksys firmware is why the recommended port to unsling to is different if you have one native disk, or two native disks.

            On normal Linux systems this would be true, but unfortunately on Unslung the
            fstab is not particularly significant. :(

                I'm running Unslung on my slug, with an ext3 disk on USB. I want to
                check the disk for file integrity and all of that good stuff, but when I
                try to execute e2fsck, I get errors related to "e2fsck: error while
                loading shared libraries: libuuid.so.1: cannot open shared object file:
                No such file or directory".

                I'm assuming that I have to uninstall and re-install some ipkg package,
                but I'm not sure which one or how to find out.

                Can anybody suggest a course of action?

                Thanks-

                  Be careful on the partition names they are different for different
                  Unslung version mine did not match the instructions.
