OT: OS X Disk Utility vs Linux

[Kurt Granroth]

Say you are experimenting with dual-booting OS X (hackintosh) on your
existing Linux machine.  A word of advice: do NOT let Disk Utility touch
your existing Linux drive in any way.  At all!  Not even to reformat one
innocent little unused partition!

If you do, then when you reboot, the BIOS won't recognize your partition
map at all and even grub won't work.  Reinstalling grub isn't enough,
either... you'll need to use fdisk to rewrite your partition table.

Now back to your regularly scheduled programming... ;-)
