Bug 1215943

Created attachment 869949 [details]
microos install log

The check-config script is reading /proc/config.gz [1], therefore using zgrep [2].

In DVD test suite the installer pulls busybox-gzip instead of gzip package.

```

Replacing busybox-gzip by gzip fixes the issue.

I filed https://github.com/k3s-io/k3s/issues/8585 as an upstream bug for this issue.

k3s check-config runs zgrep (unless on an Apparmor system, as then zgrep throws permission denied when calling out to zcat - so they detect that and fall back to an internal zcat | grep, just as if zgrep would not exist)


the zgrep file shipped as part of /busybox-gzip seems to be broken:

    while [ "$#" -gt 0 ]; do
        # shellcheck disable=SC2086
        if [ $pattern_found -eq 2 ]; then
            "zcat" -- "$1" | "grep" --label="${1}" ${grep_args} -- -
        else
            "zcat" -- "$1" | "grep" --label="${1}" ${grep_args} -- "${pattern}" -
        fi
        [ "$?" -ne 0 ] && EXIT_CODE=1
        shift
    done

buzysbox-grep does not support --label though; which essentially means, busybox-gzip would need to conflict busybox-grep to ensure the 'real' grep is there; hard to believe this would be intentional

The files zless, zmore and zgrep are from Dirk:

Indeed; apologies for that. I searched for zgrep in the changes file and only found this:

- Add zgrep to gzip sub-package

Dirk's files are indeed newer and replacing the original variants we had

I have submitted a fix for busybox-links, but I think microos tumbleweed should consider installing gzip by default..
