4.7 Yaboot: a boot loader for Macintosh PowerPC's

Yaboot is a popular boot loader for "new world" Macintosh PowerPCs. ("New-world" refers to coloured PowerPCs manufactured since 1999.)

Yaboot needs its own boot strap partition that must be at least 800k. So, if you are installing GNU/Linux from scratch, you would do something like:

(parted) mklabel mac
(parted) print
Disk geometry for /dev/sda: 0.000-6149.882 megabytes
Disk label type: mac
Minor    Start       End     Filesystem  Name          Flags
1          0.000      0.031              Apple
(parted) mkpart primary hfs 0.032 1
(parted) print
Disk geometry for /dev/hdb: 0.000-6149.882 megabytes
Disk label type: mac
Minor    Start       End     Filesystem  Name          Flags
1          0.000      0.031              Apple
2          0.031      1.000
(parted) set 2 boot on
(parted) print
Disk geometry for /dev/hdb: 0.000-6149.882 megabytes
Disk label type: mac
Minor    Start       End     Filesystem  Name          Flags
1          0.000      0.031              Apple
2          0.031      1.000                            boot

You don't need to reinstall Yaboot after resizing a partition. Yaboot is installed with ybin section 9. Related Software and Info.
