when OSX is installed on an OldWorld or with UFS filesystems it
creates two bootstrap partitions, the first being Apple_Boot the
second being Apple_Secondary or something close to that.  since i have
been using Apple_Bootstrap OSX appears to ignore ours.  (the installer
does sometimes reorder all the partitions around to put its own first,
which is annoying since it hoses /etc/fstab among other things.  its
fixable with mac-fdisk though i added explanation on how to my
mac-fdisk doc)

the MacOS does not like fake system folders of any kind, even these
fake ones you create are being deblessed and thus made unbootable by
MacOS very regularly.  i have a large mailbox of users asking me what
to do about this, i always tell them to change the partition type of
thier bootstrap partition to Apple_Bootstrap so MacOS can't see it
anymore.  that is the only solution that works 100%

thats why you don't install miboot on a newworld ;-)
