@lzaoral Would be nice to test OUTPUT=PXE as well.

PSA: I still plan to test this PR with OUTPUT=PXE. Hopefully, I'll get to it next week.

@gdha I managed to test OUTPUT=PXE sooner than expected. I've tested it only on an aarch64 OVMF Fedora 42 VM and I was able to successfully boot to the rescue environment from network with the following configuration (and necessary changes on another aarch64 Fedora 42 VM serving as a PXE/TFTP server, e.g. grub2-mknetdir, configs for dhcpd and NFS, and proper file permissions in /var/lib/tftpboot):

OUTPUT=PXE
OUTPUT_PREFIX_PXE=rear/$HOSTNAME

PXE_CONFIG_GRUB_STYLE=y

PXE_TFTP_IP=<redacted>
PXE_CONFIG_URL="nfs://$PXE_TFTP_IP/var/lib/tftpboot/boot/grub2/arm64-efi"
PXE_TFTP_UPLOAD_URL="nfs://$PXE_TFTP_IP/var/lib/tftpboot"

PXE_CREATE_LINKS=MAC
PXE_REMOVE_OLD_LINKS=y
