Machine unbootable. No Limine config. No kernel entry. Nothing

System details

Lenovo ThinkPad t480, /dev/sda, Intel CPU, Omarchy 3.5 offline ISO

What's wrong?

Exact failure chain:
1. archinstall runs, gets to bootloader step
2. Crashes with:
IsADirectoryError: [Errno 21] Is a directory: '/mnt/boot/EFI/BOOT'
DiskError: Failed to install Limine in /mnt/boot

3. archinstall then tries to copy its own log to itself and dies with a second unrelated error:
   OSError: [Errno 22] Source and target are the same path:
   '/var/log/archinstall/install.log' -> '/var/log/archinstall/install.log'

4. omarchy reports Failed script: install_base_system and exits
   5. Machine is now unbootable. No Limine config. No kernel entry. Nothing.
   Root cause:
   archinstall’s Limine integration tries to write a file to /mnt/boot/EFI/BOOT which already exists as a directory (as it should per the UEFI spec).

What should happen:
Either the installer handles this gracefully and completes anyway, OR it fails with a clear recovery path shown on screen. Instead it just dies and leaves users with an unbootable machine and no instructions.

I have no logs, it’s late night and filed it on phone

This should be fixed with the new ISO 3.5.1-2: https://iso.omarchy.org/omarchy-3.5.1-2.iso
