Upon rereading the manpage for gpart, I'm wondering if what I concluded
really happened. On closer examination, it's possible the geom logic
blocked fdisk from modifying the partition table. Can you tell me how I
can confirm out what partitioning schemes are present on my harddisk?
I put the output of gpart show at the bottom of the e-mail, which
suggests the mbr scheme is used regardless.
If geom indeed blocks fdisk from altering the partition table, I'm
wondering what the use of the binary is though, as it seems gpart does
everything fdisk does, but without failing.
# gpart show
