Updated version? - Githubissues

Hi! I'm trying to test this out (just locally with kind to start) and there is an issue with the init-headers:

Fetching upstream kernel sources for 6.5.
+ curl -skL https://www.kernel.org/pub/linux/kernel/v6.x/linux-6.5.tar.gz
+ tar --strip-components=1 -xzf - -C /linux-generic-6.5.0-1022-oem

+ cd /linux-generic-6.5.0-1022-oem
+ '[' -e /proc/config.gz ']'
+ '[' -e /boot.host/config-6.5.0-1022-oem ']'
Generating kernel headers
+ make ARCH=x86 oldconfig

And then it looks like an issue with diff:

Warning: Kernel ABI header at 'tools/arch/x86/include/asm/insn.h' differs from latest version at 'arch/x86/include/asm/insn.h'
diff: unrecognized option: I
BusyBox v1.28.4 (2018-12-31 18:05:13 UTC) multi-call binary.

Usage: diff [-abBdiNqrTstw] [-L LABEL] [-S FILE] [-U LINES] FILE1 FILE2

Compare files line by line and output the differences between them.
This implementation supports unified diffs only.

    -a  Treat all files as text
    -b  Ignore changes in the amount of whitespace
    -B  Ignore changes whose lines are all blank
    -d  Try hard to find a smaller set of changes
    -i  Ignore case differences
    -L  Use LABEL instead of the filename in the unified header
    -N  Treat absent files as empty
    -q  Output only whether files differ
    -r  Recurse
        --no-dereference Don't follow symlinks
    -S  Start with FILE when comparing directories
    -T  Make tabs line up by prefixing a tab when necessary
    -s  Report when two files are the same
    -t  Expand tabs to spaces in output
    -U  Output LINES lines of context
    -w  Ignore all whitespace

And then (maybe logically) the ebpf code does not compile in the main container:

There aren't many examples of basic setups to write and deploy an ebpf program to kubernetes, so I'm hoping we can update the example here to get it working. Thank you!
