Hello=0A=0AI'm making a dual-boot Mac mini G4 (PowerPC) which will boot Fre=
eBSD PPC and Linux Ubuntu 10.10 PPC=0A=0A=0ATo achieve that, I create parti=
tions for both the OSes. 7 partitions for FreeBSD , 3 partitions for Ubuntu=
.=0A=0A7 partitions for FreeBSD is roughly: 800~1024K apple-boot, 1G /, 1G =
FreeBSD SWAP, 600M /tmp, 600M /var, 6G /usr, 600M /home=0A=0A3 partitions f=
or Linux is roughly: 800~1024K apple-boot, 8G /, 1G SWAP=0A=0AIt looks roug=
hly like that: http://f1302.hizliresim.com/16/f/k2fqu.jpg =0A=0A=0AThe prob=
lem is, the apple-boot partitions must have some free space before them (25=
K~1M in size) in order to be detected by Ubuntu Install (or Linux GParted f=
or the same matter)=0A=0A=0AIf there's no such space before apple boot bloc=
ks, Ubuntu Install cannot see the partitions thereby making the installatio=
n of Ubuntu impossible.=0A=0AThe question is how can I properly add such fr=
ee space using FreeBSD gpart? Or using any other partitioning tool? =0A=0A=
=0AAnd advice is appreciated, thanks.=0A

You can use "-b start_offset" parameter in the gpart(8):
# gpart create -s apm ad0
# gpart add -t apple-boot -b 64 -s 800k ad0
