zfs kernel builder

Note: May update for kernel v6 Ubuntu and Proxmox (proxmox uses Ubuntu kernels), if you have suggestions, please submit a PR.

---

The stability of zfs as an in-tree module

• compiles zfs modules into kernel
• renders zfs-initramfs, zfs-dracut, zfs-dkms packages unnecessary
• build specified zfs package (has only been tested 2.0+)
• build specified kernel (v5.x.x only)
• Vanilla build system: incorporate your .config and patches as usual

Kernel portion written for debian and derivatives*

*(can be modified to compile zfs rpms, but not kernels)

To run - retrieve build dependencies:

% chmod +x *.sh
% ./install-build-requirements.sh

invoke script with $ZFS_VERSION $KERNEL_VERSION and $MAKECOMMAND (optional) Example:

% ./build-zfs-kernel.sh 2.0.3 5.10.17 modconfig

Or run without any make command - e.g.:

% ./build-zfs-kernel.sh 2.0.3 5.10.17

The above two arguments, $ZFS_VERSION and $KERNEL_VERSION are required.
