Automated modular GENTOO linux setup

status latest 07.06.23

booted to defaul desktop w cryptsetup.

work in progress, .... testing w 17.1 hardened .. first run errors resolved, boot worked - full run at once outstanding,

probably firefox build fail if on znver1 and march set to native, need to verify - busy

added optional menu to avoid the stress of commenting functions for testing to run.sh ... to run fully unattended run ./run.sh -a, for menu ./run.sh -m

removed make.conf feature flags for compress-build-logs as archives didnt open, force-mirror didnt let librsvg emerge (thx sam_ gentoo irc 4 help) and collision-protect prevented cpio to emerge for linux-firmware

brave browser, ide setup todo

status 17.09.22

Files for chroot and pre functions located in src/PRE src/CHROOT. Easy functions ON OFF gentoo_unattented-setup/run.sh

• updated https://github.com/alphaaurigae/gentoo_unattented-setup/blob/master/var/chroot_variables.sh during test setup but shouldn`t produce errors - minor.

Get started

1. Adjust var/* - default is cryptsetup / cryptsetup off works too for lvm on root. Default set as outlined below.
2. Adjust run.sh functions to run parts - useful for debugging and backup state of VM.
3. rsync reporoot to serv / chroot; sample script in script/.
4. if serv || vm ssh [email protected] && cd gentoo_unattented-setup && ./run.sh` .... repeat rsync if sections run separately ie PRE, CHROOT

• Sample setup on Virtualbox VM with bridged adaper. (Sample bridge setup in sript/)

PRE with CRYPTSETUP="YES" - CRYPTSETUP="NO" == LVM on root (successful previous test - https://github.com/alphaaurigae/gentoo_unattented-setup/blob/master/var/var_main.sh

• asciinema recording of PRE setup:
• asciinema CHROOT sample (just the start as sample, else its wayy to long obv)
• (note dated, not updated last tests) CHROOT logs attached in logdir https://github.com/alphaaurigae/gentoo_unattented-setup/tree/master/dev_log | no signifcant errors - last testrun

Boots to desktop xfce -> firefox, network, audio ...

• Basic mockup, work in progress
• Script runs with "very little" interaction required to setup a gentoo desktop. See logs.

PARTITIONING

https://github.com/alphaaurigae/gentoo_unattented-setup/blob/master/src/PRE/PARTITIONING.sh testing on 240gb VM, may requires less...

• sda single drive setup (240gb on test, may use way less...)
• sda1 bios boot
• sda2 bios boot - fs ext2
• sda3 main part - fs ext4 - lvm on cryptsetup or alt lvm on root

STAGE3

https://github.com/alphaaurigae/gentoo_unattented-setup/blob/master/src/PRE/STAGE3.sh

• curl off http://distfiles.gentoo.org/releases/amd64/autobuilds/
• GPG verify and print err if.
• unpack to chroot

PREP CHROOT

• firefox and dep libwebp take DECENT CPU TIME!!!! and require space +15gb - more time than updateworld portage & kernel... but you get the full source compiled ^^...
• chromium and oher alternatives not tested yet.

How the it works:

1.0 run.sh is the executeable file to run the scriptset.

1.1 if run.sh is run with -a it will launch the unattended setup, if launched with -m the simple bash menu will guide through the steps which is useful for testing outlined in the -h.

1.1 run.sh first sourcing func/func_main.sh (main functions used in PRE and CHROOT (sourced in chroot again)), var/var_main.sh (main variables for PRE and CHROOT (has to be sourced for chroot again in innserscript) )&& var/1_PRE_main.sh (PRE variables) at the start.

1.2 PRE: source /gentoo_unattented-setup/src/PRE/* functions & run in order defined in run.sh.

1.3 CHROOT: copy the entire gentoo_unattented-setup/ dir to chroot (CP_CHROOT function) as chroot was created in PRE, echo innerscript $CHROOTX/chroot_main.sh and execute it with chroot

... the script then sources the chroot and main functions and variables as well as the /gentoo_unattented-setup/src/CHROOT/* functions (per section (base,core etc)) and either run with menu steps if run.sh -m or just loop through every section if run.sh run with -a.

comments for the variable & script interactions partly added, most important to start is checking the var/* variables, most if not everything to be adjusted there,
