Subject: [PATCH] fix(scripts): Fedora/RHEL usan /boot/grub2/grub.cfg, no el
 wrapper EFI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Desde Fedora 34 / RHEL 9, /boot/efi/EFI/<distro>/grub.cfg es un wrapper
que sourcea /boot/grub2/grub.cfg — y grub2-mkconfig se niega a
sobreescribirlo ("will overwrite the GRUB wrapper. Please run [...] on
/boot/grub2/grub.cfg instead"). Mi loop de detección lo encontraba
primero y fallaba. Apuntamos directo al canónico.
