How to avoid systemd-boot reinstall after btrfs subvolume restoration?

My / is mounted at @ subvolume
And I have bak@ subvolume
My efi partition is mounted in /boot
I have dual boot with Windows

From time to time I mess something up in my system and if I'm not able to find a solution to undo the changes I just delete my @ subvolume and mv bak@ to @

After this I have to use pendrive with Arch installation and arch-chroot into the system to do bootctl install

Can I do something to avoid this?

There's no reason you should have to do that.

If there was a kernel update, you'll have a mismatch between the kernel on /boot and the modules in /lib/modules, but bootctl install shouldn't fix that. That would need to reinstall the kernel package.

Well, but I have.
Next time, I'll copy an error message after restoring snapshots.

Can't you use

btrfs subvolume set-default <subvol id>

to restore?
