2/28    Is it a bad thing to have more than 15 partitions (counting everything
        such as drivers, free space etc) on a hard drive?  The system is
        OS X, possibly coexisting with linuxppc, if that matters.
        \_ if every partition is as large as you will need it to be for the
           life of the disk, it's not a bad thing.
           Do you believe that's true?  -tom
           \_ That is different level of badness from what I am worried about.

              panic for unknown reason.
              kernel that can't deal with > 15 partitions but I see nowhere
              else where this is documented and it might be archaic (MkLinux).
              However I just got a kernel panic for unknown reason.
              \_ Why don't you play it safe and stay at 14 partitions?
                 \_ What does one need with 14 partitions?  mkdir.
                    \_ Mount options can only be enabled on mount points,
                       not on subdirectories.
                        \_ you're being silly.
                        \_ and a mount point is what? a subdirectory....
                           \_ You can only set nodev, nosuid on partitions
                              mounted on a particular directory. If you
                              want to run some process in a chroot env,
                              if the fake root isn't a separate volume
                              you would have to disable things like nosuid
                              on the whole volume that the fake root dir
                              located on.
                                \_ ok, you now have a (fairly specious)
                                   reason to have two partitions.  What
                                   possible reason is there for the other
                                   13?
              \_ I meant (and said) "physical" partitions, which include
                 partition map, drivers etc.  On a Mac hard drive, just 7
                 volumes will take you to 16 partitions, somtimes 18.  Any
                 way yes I can just mkdir.  Note that there are at least 3
                 types of diff. fs and os on a mac/ppc system, not counting
                 the virtual pc, and that's some motivation to have a large
                 number of partitions on a large disk.
                \_ no it's not.
