"No package busybox available." error when using centos7 ramdisk-image-create

[Pedro Sousa]

Hi,

I'm trying to create a ramdisk for centos7 using this command:

#ramdisk-image-create centos7 discovery-ironic -o my-deploy-ramdisk

and I get this error:

To build a ramdisk on rhel or centos you need to pass '--ramdisk-element dracut-ramdisk' to disk-image-create. RHEL and Centos don't have busybox so they can't use the default ramdisk element.

So while this isn't really a bug, I do think it would be good to come up with some sort of better way to handle the error, which is why I'm leaving this open as opinion instead of closing it. Maybe we could add an explicit check to the ramdisk element and if busybox isn't available we could recommend the dracut version?

I think this has been mostly fixed via Change-Id: I57ea529cf387ab8ec8497d35be19ac64198df47a
I am closing it as two years have passed, but feel free to reopen it if you think it still makes sense to track this.
