Description Thomas Stratmann 2006-03-24 05:12:31 UTC

The installation part of the ppc-specific handbook in section "7 - Configuring the Kernel" advises selecting appropriate filesystem support in "make menuconfig". However, it does not advise selecting "Partition types -> Advanced partition selection" and subsequently "Macintosh partition map support" (for mac users) or equivalently.

Forgetting this should result in a kernel that cannot up boot on such machines. Not experienced users (including users new to the platform but with experience on x86) will probably fail on this.

PPC users are expected to have run `make defconfig` as documented.
If it worked, the partition options and other required stuff would be selected.

josejx: just tried gentoo-sources & vanilla-sources, both 2.6.16, both fail:

You had to run `make defconfig`, now it's `make pmac32_defconfig`.
This has been fixed in the handbook a few days ago.
