slax

https://www.slax.org/internals.php


There are three things needed to upgrade the Slax kernel:

1) replace vmlinuz 2) replace kernel modules in initramfs image 3) replace kernel modules in 01-core.sb file

The first task is simple Second task requires you to be able to unpack and extract the contents of initrfs.img file, and then pack it back Maybe this generic howto could work: https://access.redhat.com/solutions/24029 Slax uses xz compression for initramfs if I remember correctly.

Third task requires you to be able to unsquashfs the .sb file and then mksquashfs it back You will need unsquashfs and mksquashfs commands (or sb2dir and dir2sb commands from within Slax)

Slax pack/unpack

xz -dc < /boot/initrd-$(uname -r).img | cpio -idmv

Here is what i use to repack an xz initramfs for syslinux 4.06 (live boot)

ramfs/img
#!/bin/bash
 
find . 2>/dev/null | cpio --create --format='newc' > ../initrfs.img.cpio
xz --check=crc32 --lzma2=,dict=2048kiB ../initrfs.img.cpio
mv ../initrfs.img.cpio.xz ../initrfs.img

kernel build

The kernel source tree is specified through the KERNEL_TREE environment variable. It defaults to /usr/src/linux. So either export this variable in the terminal in which you make the kernel:

export KERNEL_TREE=/usr/src/linux-3.2.61

or define a symlink from /usr/src/linux-3.2.61 to /usr/src/linux`:

ln -s /usr/src/linux-3.2.61 /usr/src/linux

Of course, replace /usr/src/linux-3.2.61 with the corresponding kernel source directory.

Then, run the following command in your kernel source directory: Code: make localyesconfig That will create a kernel with built-in support for all your hardware and not much more. As a variation which creates modules for your hardware instead of compiling the drivers right into the kernel: Code: make localmodconfig

Eric, thanks so much. In my other tab of my browser this page is open: http://alien.slackbook.org/, Can't believe I am getting a reply from yoda himself within a few minutes of posting, surely the universe is trying to tell me something

build old kernel https://www.vinnie.work/blog/2022-05-01-building-to-the-version-generation

Linux is GNU toolchain specific. In older versions of the kernel (before v4.1), there were GCC headers that were version specific (include/linux/compiler-gcc[3-5].h). This means that to build any kernel v4.0 and before you'll need a version of gcc that is version 3.x, 4.x, or 5.x. Earlier versions don't have the headers for 4.x or 5.x so you must use version 3.x. Linux 2.2 and 2.4 are highly recommended to be built with gcc-2.95.
