Port centos-minimal to yum-minimal Now that we have a generic yum-minimal element, just use it in centos instead of rinse. Adding base as an element-provides of yum-minimal because this element conflicts with the base element.

Remove EOLed CentOS 7 and RHEL 7 CentOS 7 reached EOL on 30th June 2024[1] and RHEL 7 ended its maintenance support 2 phase[2] the same date. This change removes the ablity to build images derived from these base images. The centos and centos-minimal elements now default to a DIB_RELEASE value of 9-stream.

Support secure-boot bootloader where possible As of grub2 >= 2.02-95 on redhat family distros, calling grub2-install on an EFI partition will fail with: "this utility cannot be used for EFI platforms because it does not support UEFI Secure Boot." This version of grub is now in centos8-stream and non-eus repos of RHEL-8. It is not currently possible to build whole-disk UEFI images on these distros, and when this package is promoted this will also affect centos8 and RHEL-8 eus. The grub maintainers made this change because the grub2-install generated /boot/efi/EFI/BOOT/BOOTX64.EFI will never be capable of booting with Secure Boot. This change defines a $EFI_BOOT_DIR for every distro element. When directory /boot/efi/$EFI_BOOT_DIR exists a grub.cfg file in will be generated there. This change also installs the shim package on redhat family distros, which installs a copy of the shim bootloader to /boot/efi/EFI/BOOT/BOOTX64.EFI. Using centos as an example, this allows UEFI to boot the shim /boot/efi/EFI/BOOT/BOOTX64.EFI which then chains to /boot/efi/EFI/centos/grubx64.efi. If /boot/efi/$EFI_BOOT_DIR doesn't exist (such as for Ubuntu, /boot/efi/EFI/ubuntu) the current behaviour of running grub-install to generate /boot/efi/EFI/BOOT/BOOTX64.EFI will continue. For distros such as Ubutnu where packaging does not populate /boot/efi/EFI/ubuntu with .efi files, secure boot can be added in the future by copying .efi files to /boot/efi/EFI/ubuntu and copying the shim file to /boot/efi/EFI/BOOT/BOOTX64.EFI.
