There are 7 parts to this article:
Part 1 - Gentoo on SPARC - Booting the Install CD
Part 2 - Gentoo on SPARC - Creating the Filesystems
Part 3 - Gentoo on SPARC - Copying Initial System, Portage, and Distfiles
Part 4 - Gentoo on SPARC - Creating the Kernel
Part 5 - Gentoo on SPARC - Getting Silo Installed
Part 6 - Gentoo on SPARC - Initial Logon
Part 7 - Gentoo on SPARC - Final Configuration

Let's chroot into the new filesystem and set up the environment:

livecd distfiles # mount -t proc none /mnt/gentoo/proc
livecd distfiles # chroot /mnt/gentoo /bin/bash
livecd / #
livecd / # env-update; source /etc/profile
>>> Regenerating /etc/ld.so.cache...
* Caching service dependencies...livecd / #
livecd / #

Set up the timezone:

livecd / # ls /usr/share/zoneinfo/US
Alaska    Arizona  East-Indiana  Hawaii          Michigan  Pacific
Aleutian  Central  Eastern       Indiana-Starke  Mountain  Samoa
livecd / #
livecd / # ln -sf /usr/share/zoneinfo/US/Pacific  /etc/localtime
livecd / #

Set up the filesystem configuration in fstab:

livecd / # cat /etc/fstab
#                                 

/dev/sda2   none            swap            sw                      0 0
/dev/sda1   /               ext3            noatime                 0 1
/dev/cdroms/cdrom0 /mnt/cdrom      auto            noauto,user             0 0
none  /proc           proc            defaults                0 0
none  /dev/shm        tmpfs           nodev,nosuid,noexec  0 0

Now, we need to install the kernel sources using emerge:

livecd / #
livecd / # emerge sparc-sources
Calculating dependencies ...done!
>>> emerge (1 of 2) app-admin/addpatches-0.2 to /
*** Adjusting cvs-src permissions for portage user...
>>> Unpacking source...
>>> Source unpacked.
>>> Test phase [not enabled]: app-admin/addpatches-0.2
>>> Install addpatches-0.2 into /var/tmp/portage/addpatches-0.2/image/ category
app-admin
>>> dobin: making /usr/portage/app-admin/addpatches/files/addpatches executable.
..
man:
prepallstrip:

>>> Completed installing into /var/tmp/portage/addpatches-0.2/image/

>>> Regenerating /etc/ld.so.cache...

>>> clean: No packages selected for removal.
>>> emerge (2 of 2) sys-kernel/sparc-sources-2.4.27 to /

.
>>> /usr/share/doc/sparc-sources-2.4.27/patches.txt.gz
* After installing a new kernel of any version, it is important
* that you have the appropriate /etc/modules.autoload.d/kernel-X.Y
* created (X.Y is the first 2 parts of your new kernel version)
* For example, this kernel will require:
* /etc/modules.autoload.d/kernel-2.4
*
* For users with an Enterprise model Ultra 1 using the HME network interface,
* please emerge the kernel using the following command:
*
* USE=ultra1 emerge sparc-sources
*
>>> Regenerating /etc/ld.so.cache...
* Caching service dependencies...>>> sys-kernel/sparc-sources-2.4.27 merged.
>>> Recording sys-kernel/sparc-sources in "world" favorites file...
>>> clean: No packages selected for removal.
>>> Auto-cleaning packages ...
>>> No outdated packages were found on your system.
* GNU info directory index is up-to-date.
livecd / #

The default configuration (.config) worked well on both systems, but we still peeked with menuconfig:

livecd / # cd /usr/src/linux
livecd linux # make menuconfig
rm -f include/asm
( cd include ; ln -sf asm-sparc64 asm)
make -C scripts/lxdialog all
make[1]: Entering directory `/usr/src/linux-2.4.27-sparc/scripts/lxdialog'
gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -DLOCALE  -DCURSES_LOC="<
ncurses.h>" -c -o checklist.o checklist.c
gcc -Wall -Wstrict-prototype
.
.
.
|   Do you wish to save your new kernel configuration?     |

Saving your kernel configuration...
*** End of Linux kernel configuration.
*** Check the top-level Makefile for additional configuration.
*** Next, you must run 'make dep'.
livecd linux #

Compile and install the kernel and modules:

livecd linux # make dep && make clean vmlinux image modules modules_install
gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/mkdep scripts/
mkdep.c
make -C arch/sparc64/kernel check_asm

.
cd /lib/modules/2.4.27-sparc; \
mkdir -p pcmcia; \
find kernel -path '*/pcmcia/*' -name '*.o' | xargs -i -r ln -sf ../{} pcmcia
if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.4.27-sparc; fi
livecd linux #
livecd linux # cp arch/sparc64/boot/image /boot/kernel-2.4.27
livecd linux #
livecd linux # cp System.map /boot
livecd linux # exit

In the next installment of this article, we will set up silo.
