Discovery iso: Missing EFI file (/boot/efi/EFI/*/gcdx64.efi)

Support
1

Hello,

I'm rolling my own discovery iso but UEFI support seems to fail during
build.

Building on a CentOS 7.2 host running build-livecd then build-livecd. The
ISO builds OK and is bootable from legacy BIOS but I need to boot UEFI
hosts too.

I have the below in my 20-packages.ks

grub2-efi
efibootmgr
shim

Missing EFI file (/boot/efi/EFI/*/gcdx64.efi)
Failed to copy EFI files, no EFI Support will be included.
usage: mkefiboot [-h] [–debug] [-d] [-a] [-l LABEL] [-i ICONFILE]
[-n DISKNAME] [-p PRODUCT]
EFIBOOTDIR OUTPUTFILE
mkefiboot: error: /tmp/imgcreate-1xfrZU/iso-E4oXxM/EFI/BOOT is not a
directory
usage: mkefiboot [-h] [–debug] [-d] [-a] [-l LABEL] [-i ICONFILE]
[-n DISKNAME] [-p PRODUCT]
EFIBOOTDIR OUTPUTFILE
mkefiboot: error: /tmp/imgcreate-1xfrZU/iso-E4oXxM/EFI/BOOT is not a
directory

  • ensure /etc/os-release is present (needed for RHEL 7.0)

What am I missing here? Any help would be appreciated.

Thanks,

Hello, we do only build on Fedora, the livecd tooling in RHEL7 might
be little bit outdated.

What is the reason for shim/efibootloader in discovery image? You want
SecureBoot over PXE?

Worked for me on Fedora, do a PR and I can add those files into the
official build.

Hi LZ, thanks for the reply.

Do you have any specifics around your Fedora build env?

Using a fresh Fedora 26 install and latest master.zip, I'm modifying
00-repos-f21.ks and pointing to nightly f24. At which point the
build-livecd-root finishes but I get an offensive message:

dracut: dracut module 'dmsquash-live' cannot be found or installed.
mkinitrd failed

Followed by:

The ISO image doesn't look like a LiveCD ISO image to me.

Which version of Fedora are you building on and what is the contents of
your fedora ks files?

Thanks a lot.

I am on latest stable Fedora, haven't done anything special, but this
is my development instance, I might have some packages that clean
installation don't have. It should be as easy as:

https://github.com/theforeman/foreman-discovery-image#building

Quick look into yum/dnf database shows this package you are missing: dracut-live

Try to grab it and see if it works, file a README update if you are
using clean environment, there might be other missing bits, thanks!
