[SOLVED] Confused about EFI partition

I'm confused about EFI partition. During arch installation I've mounted it, but somehow it's not mounted anymore.
I don't know if I should have it always mounted or not.

➜  ~ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 238,5G  0 disk 
├─sda1   8:1    0   200M  0 part 
├─sda2   8:2    0   500M  0 part 
├─sda3   8:3    0    76G  0 part /
└─sda5   8:5    0 161,8G  0 part 

➜  ~ df -h

tmpfs           1,6G   12K  1,6G   1% /run/user/1000

➜  ~ cat /etc/fstab

Re: [SOLVED] Confused about EFI partition

Well apparently you did run genfstab before mounting the ESP. Which isn't a problem, just manually add the relevant entry (or rerun genfstab after ensuring all are mounted).

Re: [SOLVED] Confused about EFI partition

OK, I extended /etc/fstab with genfstab output for /dev/sda1. Thx for quick help. Marking solved.

Re: [SOLVED] Confused about EFI partition

I don't know if I should have it always mounted or not.

If  you're mounting the ESP under /boot then systemd will automount it on demand without any fstab entries at all and keep it unmounted otherwise.

Reference: https://www.freedesktop.org/software/sy … rator.html

Some forum members have suggested this may cause problems during kernel updates but I've never experienced that myself, the ESP has always been automounted correctly for the update in my systems.

Off-topic for this thread but I don't think you should mount your storage device under /mnt because hier(7) defines that as " a mount point for a temporarily mounted filesystem". But it's your system

Good catch. What would be better mount point? simply /storage?

Re: [SOLVED] Confused about EFI partition

It shouldn't matter as long as is doesn't conflict with the file-hierarchy(7).
The wiki lists /data as an option, so you can use that (that's what I do).
