 Posted: Fri Mar 21, 2025 2:41 pm Post subject: Installing Gentoo use a bash script? |
 |
|
Hey, everybody!
Guys, I have a strange desire to make an installation of Gentoo for myself, installation bash script, booting from the boot drive (example ubuntu, arch, it does not matter).
I sat for a while and wrote a script, but I'm not sure if I did it right  , can you point out the mistakes to me?
Yes, I plan to test it some more on a VM before using it on a install PC, but if you don't mind, can you email me where my errors are?
Thx!

escfrpls,
Welcome to Gentoo.
There is a serious lack of error checking/handling.
| Code: | # --------------------------
# Password Input
# --------------------------
read -sp "Enter root password: " ROOT_PASS
echo
read -sp "Enter password for $USERNAME: " USER_PASS
echo |
Require the passwords to be entered twice and compare the entries.
| Code: | # --------------------------
# Disk Preparation
# --------------------------
wipefs -af $DISK |
That will ruin you whole day if the disk is fat fingered.
| Code: | | STAGE3_URL=$(curl -s https://distfiles.gentoo.org/releases/amd64/autobuilds/latest-stage3-amd64-openrc.txt ... |
but I'm installing on arm64 ...
OK that' out of scope :)
I understand we have a few systemd users too :)
| Code: | echo "Extracting stage3..."
tar xpvf /mnt/gentoo/stage3.tar.xz --xattrs-include='*.*' --numeric-owner -C /mnt/gentoo |
Do you really need the -v option?
It only slows things down.
| Code: | | COMMON_FLAGS="-march=znver4 -O2 -pipe" |
That's not generally applicable. I have a zen3, others have Intel CPUs
Build and run | Code: | | app-misc/resolve-march-native |
and use whatever that spits out.
You do that already for cpuid2cpuflags, I think.
| Code: | | CONFIG_DRM_AMDGPU=y |
make that a module or include the firmware into the kernel binary.
Not everyone will have an AMD GPU.
Where do you set the profile?
latest-stage3-amd64-openrc.txt has a profile set but is it correct?
USE
are included in a desktop profile.
USE
Chose the right profile and get these for free.
Over my dead body
| Code: | net-im/signal-desktop-bin \
net-im/discord-bin \ |
Some of the packages you emerge should not be listed in the world set.

Oh yeah, I use, my processor 7900xtx and my video card is from 7900xtx.

Mmm, I don't get it. I don't want to use the system, so I have to choose arm64?

That's right, my typo.

It's not critical, you don't have to install it hehe
thanks for the tips! |

I think you could distill the script down into essential steps, and add a few variables, maybe for things like architecture type or compiler options, that way the script does more than install your exact preferences.

escfrpls,
Gentoo supports many different architectures.
Your script hard codes amd64 with openrc on zen4. That will be a small subset of Gentoo installs.
amd64 is correct for you.
I have amd64 and arm64 here.
I was trying to get across that your script would be more generally useful if the user could choose the CPU architecture, openrc/systemd and profile.
zen_desu provided further hints.
AMDGPU cannot work without its firmware.
The firmware must be available when the module is initialised.
If you set AMDGPU=y, thats before the root filesystem is mounted, so the firmware must be included in the kernel binary.
When AMDGPU=m, the firmware can be read from /lib/firmware and AMDGPU will help itself to the right firmware.
The kernel will become huge trying to cater to different GPUs, even just AMD GPUs.
As it stands, your script may work in a VM, as it won't use AMDGPU but all you will get on real hardware is a blank console.
At least, it will be blank after AMDGPU starts with no firmware.

Thanks for the advice, the topic can be closed.
Probably you are right, it will be easier for me to install the base system and then automate the installation with a script (everything else) - it will be faster and easier.
Thanks again for the advice! |
