Hey, I’ve been trying to install Gentoo and I keep running into the same issue every time I install "sys-kernel/gentoo-kernel-bin".

During the install, it fails with:

* ERROR: sys-kernel/gentoo-kernel-bin-...::gentoo failed (postinst phase):
*   FAILED postinst: 1

Looking at the output, the actual error seems to be coming from dracut:

dracut: Can't write to /boot/efi/Default/...
Directory does not exist or is not accessible

My setup:

- OpenRC (not systemd)
- Using EFI
- "/boot/efi" is mounted properly
- I’m planning to use GRUB

What I’ve already done:

- Installed all required packages:
  - "sys-kernel/installkernel-gentoo"
  - "sys-kernel/dracut"
  - "sys-boot/grub"
- Verified "/boot/efi" is mounted
- Tried running "dracut --force" manually (same error)
- Retried "emerge --config sys-kernel/gentoo-kernel-bin"
- Still getting the same failure

What confuses me:
It keeps trying to write to:

/boot/efi/Default/

which looks like some kind of systemd-boot / UKI layout, but I’m on OpenRC and using GRUB.

Questions:

- Why is it trying to use "/boot/efi/Default/" instead of "/boot"?
- Is this expected behavior with gentoo-kernel-bin + dracut?
- Do I need to change "installkernel" or dracut config?
- Should I just switch to "sys-kernel/gentoo-kernel" instead?

---

If anyone has run into this before or knows what I’m missing, I’d really appreciate the help. I feel like I’ve installed everything correctly but I’m clearly missing something.

Thanks 🙏

gentoo-kernel-bin FAILED postinst: 1 (dracut /boot/efi issue?) – need help
