Thank you very much all, for your inputs !

I’ve did

root: file /boot/broadcom/initrd.gz
initrd.gz: Zstandard compressed data ....

root: unmkinitramfs /boot/broadcom/initrd.gz Extracted/
# data where extracted to Extracted/
# but I go few error like:
# cpio: cannot link usr/sbin/vconfig to usr/sbin/watchdog: Operation not permitted

Extracted//

|   |-- arch.conf*
|   |-- conf.d/

|-- etc/

So it tend to confirm that even if the file is named initrd.gz it’s actually an initramfs method… ( damn this is so misleading )

So I guess I can follow preparing-linux from the guide and overwrite the initrd.gz ?

Thanks @SteveTech@programming.dev

I suppose the file linux/arch/Kconfig is the base the menuconfig to know which option is available ? right ?

Thanks.

Thanks, how can we verify this ?

I’m using Devuan ( systemd free ! ) :)

I believe my initramfs do not support luks encryption, but the link of @DrDystopia@lemy.lol might work… 🤞

Thanks @DrDystopia@lemy.lol ! indeed https://github.com/gitbls/sdm/blob/master/Docs/Disk-Encryption.md#the-sdm-cryptconfig-script seem what I need. I’ll try

ohh ! great ! I’ll see if I manage to install it on Devuan Thanks.

🤩 Woo I didn’t know nix. It seem a better way to handle package !!!
But so if I have already apt that handle packages, is it compatible to use both on the same system !?

Nix stores all packages in isolation from each other; as a result there are no /bin, /sbin, /lib or /usr directories and all packages are kept in /nix/store instead.

Yes, but it’s not reliable. because even if you use a bare linux vm to download the packages and dependency, you never know if the online will have already a dependence that the offline system do not have.

no, the only way is to force the dw of the already downloaded package.

Thank you very much @connaisseur@feddit.org

I have tried

apt-get -o Dir::Cache::archives="/to/path" install --download-only apt-offline

But it downloaded only the .deb of apt-offline and not all the dependence tree. Most probably because this machine have them already.

now, remain to force to download also all the dependency tree even if already installed…

indeed .appimage are an amazing thing as they do not require any special runtime or installation process !
I guess I will have to do my own .appimage of software that do not provide them

AppImage !

• Open format? Yes
• Free format? Yes
• Fully Contained Single Executable Support . Like an exe file for Windows systems Yes (the only one)
• App Size** The lowest** !

Thank you very much @taaz

So you say 2 but with unix socket so it the same as my proposal number 3 ? no ?

I’ll check capabilities

indeed I need it to be scriptable.
