No longer able to mount ESP to /efi

Description of the issue

I am trying to set up partitoning for Snapper with BTRFS and am trying to set the mount point of the boot partition to /efi instead of /boot per the Wiki. However, I'm encountering "Boot partition not found" when trying to "Install", presumably due to the changes in #3336 where is_boot has been updated to explicitly check that self.mountpoint == Path('/boot').

Am I misunderstanding how to config Snapper & BTRFS for snapshot support or is that PR a regression?

Virtual machine config:

VMware Workstation Pro

It appear an oversight occurs as there are TWO possible "boot" partitions: /boot and /efi. The problem is, the /efi check is performed AFTER the script returns on the missing /boot partition. It does not appear /efi ever gets checked at that point.. The boot partition check should be a single evaluation with an if efi exists {} else if boot exists{} {else fail}. EFI has been the default for a while for most distributions. In my opinion it should be the default.

The error does not occur (for me) in the 20250501 iso with archinstall 3.0.4, while it does in 3.0.7.

What about /boot/efi?

I don't know if still the case, it used to be the default for several distributions in the past.

Same issue here, "boot partition not found" even though I mounted it to /boot/efi

This is still an issue in 2025.07.01

Can confirm as of 2025.7.23 it is still present in the ISO.

Can confirm as of 2025.7.23 it is still present in the ISO.

The ISO only changes once per month, so unless you follow the README and use the git version, the ISO will not have a fix automatically until next month.

Is the issue foxed in the git version though?

Once the #3659 PR is merged, I will try to fix the merge conflicts during late CEST, it should be working.

After that I'll coordinate a release as well, so people can just do pacman -Sy archinstall.

[Torxed]

Verified that the PR in question works.
Here's the steps/setup I used to test this:

Mountpoints and flags

archinstall disk step

Bootloader

⚠️ systemd-boot does not support this setup

I'd be interested as well in /boot/efi, which is still the default of several distributions even now...
