Summary

We contributed https://github.com/dracutdevs/dracut/commit/67591e8855006eb02aa0ffab7349ab770e471473 / https://github.com/dracutdevs/dracut/issues/2323 to upstream dracut, but since it hasn't made it into ver. 59 yet we have a patch. See https://github.com/microsoft/azurelinux/pull/5424 for details.

This patch adds a requirement on awk to prep an initramfs that isn't present in Fedora etc., so likely isn't found in any other .spec for dracut.

This failure is non-fatal since the fallback path of cache-miss still works (as it did for the selinux errors), but the log is very ugly:

WARN[0022][imager] initramfs 3.0-3.azl3 posttrans

Adding a Requires: gawk fixes this error. Checking the change in runtime requirements (as understood by our build tools via depsearch) gives gawk and mpfr as new (853K + 358K = 1.2M)
