boot.mount slowing down boot process

I recently reinstalled arch on my laptop to use LUKS encryption.

However, I am noticing slower boot times and the problem appears to be boot.mount, according to systemd-analyze.

systemd-analyze
Startup finished in 6.904s (firmware) + 1.248s (loader) + 1.509s (kernel) + 2.754s (initrd) + 13.436s (userspace) = 25.854s
graphical.target reached after 13.436s in userspace.

This happens even when removing it from /etc/fstab.

I currently have a boot partition and a an encrypted btrfs partition containing @ and @home subvolumes

lsblk -f
nvme0n1
├─nvme0n1p1 vfat        FAT32       890D-A1A5                             492.9M    10% /boot

Let me know if there's anything else I could add.

Re: boot.mount slowing down boot process

as you clearly not followed it - start over here: https://wiki.archlinux.org/title/Installation_guide
we can't support whatevery really bad instructions you followed (likely some random guide, a yt video, or worst: some ai)

a few points:
- why remove /boot from fstab? - your very next topic will be "system not booting after kernell update" - caused by: /boot not mounted during update
- syslx64.efi? unless you really try to use syslinux that's a rather strange name
- btrfs in a luks container is only useful for snapshots and has a high impact on scrubbing

Re: boot.mount slowing down boot process

I did, what would make you think I didn't?

why remove /boot from fstab?

I did not. I did that temporarily to check whether that would fix the issue. It didn't. I know it needs to be there

syslx64.efi?

Where did you even read that. Regardless, I'm booting from a UKI

btrfs in a luks container is only useful for snapshots and has a high impact on scrubbing

Have you taken a look at the journal? If you want us to ta look too:

Re: boot.mount slowing down boot process

At 13:07:14 mounting /boot starts, then there's

systemd[1]: Listening on Disk Image Download Service Socket.

and it takes about 11 seconds until

systemd[1]: Mounted /boot.

Maybe some VM stuff?

Re: boot.mount slowing down boot process

Well - this looks a bit odd.

One thing to note is that the dirty bit of your boot partition is set and fsck removes it. That sounds like a mishap on shutdown or reboot. That doesn't take very long - it's just odd.

The 11 second time jump in the log looks like it's cause is the boot partition mount but it's probably a coincidence.

Can you provide another log with disabled mount of the boot partition?

Re: boot.mount slowing down boot process

Not on a vm. XPS 9320 (i7 1260P, secure boot)

One thing to note is that the dirty bit of your boot partition is set and fsck removes it. That sounds like a mishap on shutdown or reboot. That doesn't take very long - it's just odd.

Noticed that too. It happens consistently, even if I run fsck manually after boot

Something odd I just noticed, /dev/nvme0n1p1 is being mounted even without it being in /etc/fstab. Huh? http://0x0.st/8Vr8.txt

My first thought was "well that's probably systemd", however..

Legend: LOAD   → Reflects whether the unit definition was properly loaded.
        ACTIVE → The high-level unit activation state, i.e. generalization of SUB.
        SUB    → The low-level unit activation state, values depend on unit type.

Just in case:

systemctl cat boot.mount

It looks like systemd isn't automatically mounting /boot, however it's still there in crytical-chain and the boot partition is, indeed, mounted

This would explain, why excluding "boot" from fstab had no effect.

Check those:

ls -la /boot/EFI/systemd
ls -la /boot/EFI/loader
systemctl status systemd-boot-update.service
efibootmgr

Re: boot.mount slowing down boot process

/boot/EFI/systemd doesn't exist, as expected
/boot/EFI/loader doesn't exist, I think you meant /boot/loader, which only contains the random-seed file (why would it, though?)

/boot

├── intel-ucode.img

systemd-boot-update.service is disabled and there is no output, so nothing noteworty

Re: boot.mount slowing down boot process

I might have found a "fix", will have to do some further research on why it worked

I removed /boot from fstab and masked boot.automount

After a reboot, boot.mount was gone and boot was not getting mounted (as expected). iwd.service appears to be taking up those 10 seconds now, the boot time did not change.

Disabling iwd.service (as NetworkManager starts it anyway, so it isn't really needed) fixed the boot time

Startup finished in 6.888s (firmware) + 1.268s (loader) + 1.519s (kernel) + 2.702s (initrd) + 1.770s (userspace) = 14.149s
graphical.target reached after 1.767s in userspace.

I will now try to unmask boot.automount and/or re-add /boot to fstab.

Here is a boot with a masked boot.automount, no /boot in fstab and disabled iwd.service: http://0x0.st/8VKT.txt

edit: Looks like adding back either one of those 3 things (iwd, automount or fstab entry) adds the delay back. iwd doesn't seem to be related in any way (it still takes 6 seconds to launch, as reported by systemd-analyze blame, but likely simply doesn't slow the boot when not explicitly enabled), so I'll just assume it takes some time for it to start after the system powers on. So the problem is likely still just the boot partition. Mounting it manually, even with the same args used in fstab, is fairly quick. Running fsck manually on it doesn't show anything unusual.

I could consider adding a custom systemd service that mounts the boot partition later, which of course would just be a workaround and not a clean fix, something like

# /etc/systemd/system/mount-boot-later.service
[Unit]
Description=Late mount /boot
After=multi-user.target
ConditionPathExists=/dev/disk/by-uuid/890D-A1A5

[Service]
Type=oneshot
ExecStart=/usr/bin/mount /dev/disk/by-uuid/890D-A1A5 /boot -o rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro

[Install]
WantedBy=multi-user.target

This works, but as I said, I would much prefer finding the cause of the delay in the first place. Also, in systemd-analyze-balme, I can still see how this service takes over 10 seconds to launch, just dosn't clog the boot process while starting

The build process for UKI's seems to add "bootctl" functionality - this in turn creates the seed file.
I've seen this in my UKI boot too.

Some other things I noticed: Your startup summary contains an extra entry for "initrd" - mine (UKI/non-UKI) doesn't.
You seem to have enabled "onedriver", which starts before the network is up.

Re: boot.mount slowing down boot process

I am encoutering the same issue on a Dell XPS 9340. (Almost the same device as your 9320).

For some unknown reason the boot.mount is taking 10 seconds slowing down startup by 10 seconds. It didnt do this until somewhere last month I'd say. Startup used to be almost instant.

$ systemd-analyze blame
10.969s boot.mount

Re: boot.mount slowing down boot process

Nice to know I'm not alone

You can also try my workaround

remove the boot partition from /etc/fstab, then create a file /etc/systemd/system/mount-boot-later.service

[Unit]
Description=Late mount /boot
After=multi-user.target
ConditionPathExists=/dev/disk/by-uuid/890D-A1A5

[Service]
Type=oneshot
ExecStart=/usr/bin/mount /dev/disk/by-uuid/890D-A1A5 /boot -o rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro

[Install]
WantedBy=multi-user.target

and then

# systemctl enable mount-boot-later.service
# systemctl mask boot.mount
# systemctl mask boot.automount

I think I removed the seed file with "bootctl remove" or something similar. I deleted the loader folder and doesn't get created anymore.

Mh, none of those should be an issue, though

Re: boot.mount slowing down boot process

I am also experiencing this issue, Dell XPS 9640 here (is it a Dell specific thing?).

My /boot partition is not encrypted, the rest is encrypted and I do not use secure boot.

I am currently running the linux-lts kernel, and I have been able to trace the issue back to kernel 6.12.19.
Reverting to 6.12.18 fixes the issue for me. I do not know how this translates on the stable branch.

The culprit might be somewhere there: https://lore.kernel.org/stable/20250313 … c7@gregkh/

Can you try reverting / installing kernel 6.12.18 and see if it fixes the issue for you?

Re: boot.mount slowing down boot process

After reinstalling Arch the boot.mount item doesn't take 10 seconds anymore, only 188ms now.

Edit: I did also disable the webcam from the BIOS, this seems to be the real "fix" and not the clean installation.

Re: boot.mount slowing down boot process

I still have that issue after reinstalling, however I did not re-create any partitions, just cleared them,

Re: boot.mount slowing down boot process

sincerely, what the fuck, intel? I get that IPU6 on linux is a mess, but how could it possibly interfere with a partition not mounting properly.

Thanks for pointing that out. It does indeed fix the issue for me too.
