[SOLVED] Switching from efistub to systemd-boot

nierro · 2015-05-28 07:56:08

Hi!
I'm currently using efistub (efibootmgr) to boot; btw i'd like to switch to systemd-boot (because of ease of configuration).
I'm mounting esp in /boot from fstab:

/dev/sda2 /boot vfat defaults,noatime 0 0

Should i just run "sudo bootctl install /boot" ?

And...from the systemd 220 changelog:

The EFI System Partition (ESP) as mounted to /boot by
systemd-efi-boot-generator will now be unmounted
automatically after 2 minutes of not being used. This should
minimize the risk of ESP corruptions.

1) Does that mean i can get rid of my /boot entry in fstab because it will be automatic mounted from systemd?
2) What if I upgrade my kernel after 2 minutes and the esp is already unmounted?

Thanks!

I enabled and started systemd-boot and removed gummiboot. It appears to be working properly on my system, but I had only built it yesterday evening after the abs was updated (220-3). As for the /boot unmounting, I don't know if it will automagically re-mount if you need to write to it.... I guess that's why we're testing it, eh? I'm going to try commenting out the /boot entry in fstab and do a couple reboots to see if it works properly later on this evening, when I get home from work. Or you can test it for us?

edit: decided to try commenting out my boot entry and rebooted.... seems to work, I booted.. And after a little thought, I guess you can wait a few minutes for /boot to unmount then rebuild your initramfs (mkinitcpio) and see if it errors out on you.

What do you mean with "enabled and started systemd-boot"?
By the way i guess i should "install" it in /boot, but i don't know if i have to do something else (as i was previously booting directly from uefi).
And, as this is a critical part of my system, and i don't want to find myself with an unbootable system, i'll wait for more clarifications
Thanks!

Ok, i managed to get it working by issuing a "bootctl install" and by copying sample config from /usr/share/systemd/bootctl/arch.conf to /boot/loader/entries/ (and configuring it), plus i had to configure
/boot/loader/loader.conf too.
Everything is working well, boot is automounted. I'm checking if it gets unmounted after 2 minutes being unused right now.
I'll mark the thread as solved

EDIT: aaaand yes, /boot gets automounted when needed. Proof:
