"Re-use" your Armbian-built system to deploy Gentoo

Move the contents of the Armbian root filesystem, install gentoo stage 3, and restore boot directory. Start by mounting the boot media (SD Card) on another workstation that has internet connectivity. Note: if possible, use another arm64 system so subsequent chroot steps will be possible.

root #mount /dev/sdx1 /mnt/gentoo
root #cd /mnt/gentoo
root #mkdir armbian_rootfs
root #mv -v * /armbian_rootfs/ # ignore error about moving this directory into itself
root #cat stage3-*.DIGESTS
root #sha512sum stage3-arm64-openrc-20240505T234912Z.tar.xz
(compare to saved hash)
  • (continue, basically as outlined in Gentoo Handbook (amd64)
root #tar xpvf stage3-*.tar.xz --xattrs-include='*.*' --numeric-owner

Assemble a Gentoo system from scratch

Layout media and install base system

  • Prepare media (microSD card for u-boot, kernel, initramfs; optional additional media for rootfs -- can be NVMe or other via USB stick, luks encrypted, with lvm volumes for Gentoo rootfs.)
  • Install u-boot, kernel, and initramfs to boot device; optionally use serial console to observe u-boot handoff to initramfs and kernel (consult User:Brendlefly62/Rockchip RK3588S Rock 5c/Build-Install-U-Boot )
  • Install Gentoo rootfs as stage3 (Consult Handbook:Main_Page)
  • See above; follow handbook install process all the way to boot and add local user.

Install joetoo repository

  • Install dev-vcs/git and eselect-repository and add joetoo repo
root #nano /etc/portage/repos.conf/eselect-repo.conf
# created by eselect-repo
[joetoo]
location = /var/db/repos/joetoo
sync-type = git
sync-uri = https://github.com/JosephBrendler/joetoo.git

Prepare to install software

  • Configure system USE flags
root #nano /etc/portage/package.use/joetoo
# This package.use file enables the tailored configuration of a joetoo system

#-----[ standardized TARGETS for joetoo ]-------------------------------
# This section is self-explanatory.  Note that default CPU flags are set in the included file
# /etc/portage/package.use/00cpu_flags and are commented out by default because they depend on arch
# Note that many other standardized configuration choices are provided in the included default
# make.conf file
*/* PYTHON_TARGETS: -python2_7
*/* PHP_TARGETS: php8-3
*/* RUBY_TARGETS: ruby31
*/* LLVM_TARGETS: ARM X86
  • Verify CPU_FLAGS and COMMON_FLAGS with cpuid2cpuflags and resolve-march-native
root #nano /etc/portage/make.conf
COMMON_FLAGS="-O2 -pipe  -mcpu=cortex-a76.cortex-a55+crc+crypto"
root #nano /etc/portage/package.use/00cpu-flags
*/* CPU_FLAGS_ARM: edsp neon thumb vfp vfpv3 vfpv4 vfp-d32 aes sha1 sha2 crc32 asimddp v4 v5 v6 v7 v8 thumb2
  • Install dev-embedded/sbc-headless-meta::joetoo with USE including "joetoo rk3588s-rock-5c" (also opt out of getting kernel and boot firmware, for now)
root #emerge -av dev-embedded/sbc-headless-meta::joetoo
  • This will select joetoo-base/joetoo-meta::joetoo which installs standard software according to USE flags, and basic joetoo .conf files for these software packages. ==> configure those
root #dispatch-conf

Install tools

  • Install dev-util/joetoolkit::joetoo and use get_my_cflags.sh to double-check

Finalize

  • update with app-portage/jus::joetoo (joetoo update sequence)
  • rebuild the entire system with rus (rebuild update sequence) script from app-portage/jus
