Is there an x86_64 syslinux isolinux.bin equivalent for supporting eltorito boot install ISOs for aarch64? It’s in the standard and non-RHEL-derived bundles’ forums imply support for this but it doesn’t appear to be added [yet?] to RHEL derivative bundles.
Background: I’m standing up a Fujitsu ARM64FX (HPE) cluster with x86_64 infrastructure nodes and ARM computes. I’d prefer to uniformly apply the practice of repackaging the applicable boot/install ISO with an injected kickstart, mainly because hardware availability for a more traditional local-storage or pxe install is going to be rare and virtualization support --depending on your chosen flavor – is either not working, not supported, or not allowed in the parent enclave. (Yes I’m mainly thinking about decisions now establishing untenable management practices and procedures later. This is a preference, not a hard requirement, in a pinch I can always pxe the first compute with a dracut pre-pivot breakpoint on the stock aarch64 dvd1 ISO and manually console it from there.)
There are any number of examples online for doing this with ARM in general for non-RHEL-derived bundles. Most include eltorito support via the expected addition of a boot image binary and catalog; mkiso*, genisoimage, and many others all do essentially the same thing. There’s no syslinux packaged for aarch64 and the rest of the usual gubbins are there in the prepackaged boot/install ISOs just as you’d expect (/boot.catalog, /images/[pxeboot/]*img and vmlinuz, etc). So now I’m wondering if eltorito is actually a thing for aarch64 in the RHEL world…
