I am trying to document how the partitions are laid out in FreeBSD and I
have noticed that the installation will place the sector offsets of the
b (swap) partition before the last partition. And will also place the
sector offsets of the largest partition as the last regardless to its
name (ie: d or h)

The question is why ? is it due to performance reasons ? or safety ? or
other ? I have looked for specific documentation on this but I can't
seem to find it.

thanks in advance !

here is an example:

#        size   offset    fstype   [fsize bsize bps/cpg]
a:   262144        0    4.2BSD     1024  8192    16   # (Cyl.    0 -
260*)

######swap partition sectors start right befiore the d partitions
