hello. since i work on #63166 <https://bugs.archlinux.org/task/63166?project=6>i have sum questions about archiso project.
As far as I understand, two loaders are used. syslinux for bios and systemd-boot for efi. is it so? and why it is so?
* because systemd-boot does not support non-efi * syslinux may not work on efi (at least it does for few machines I tested). * systemd-boot is the... maybe bring most features to systemd...
i modified syslinux config <https://github.com/alex19EP/talkingarch/raw/accessible-upstreem/configs/releng/syslinux/archiso_sys.cfg> to add another entry with kernel cmdline options. do i need to add another file in configs/releng/efiboot/loader/entries for efi support?
yes
why are archiso-x86_64-cd.conf and archiso-x86_64-usb.conf?
One for USB EFI boot, the other for the vintage DVD/CD mode in EFI ("El Torito")
thanks.
