[Solved] Pacman tells me "Current root is not booted"

Ever since I switched from GRUB to systemd-boot, I've been getting those weird pacman messages related to root not being booted:

:: Running post-transaction hooks...
( 1/10) Reloading system manager configuration...
  Skipped: Current root is not booted.
( 2/10) Reloading user manager configuration...
  Skipped: Current root is not booted.
( 3/10) Updating udev hardware database...
( 4/10) Reloading device manager configuration...
( 5/10) Arming ConditionNeedsUpdate...
( 6/10) Reloading system bus configuration...
  Skipped: Current root is not booted.

But I am booting as normal into the system, not chrooting into it. I have also confirmed that I am booting with systemd-boot.

Just for testing, I deleted everything from /boot, repopulated the kernel and initramfs files in /boot with `sudo pacman -Syu linux` and re-installed systemd-boot with `sudo bootctl install`. No change it seems.

Some info about my setup:

~ $ lsblk -f 
NAME  FSTYPE FSVER LABEL UUID                                 FSAVAIL FSUSE% MOUNTPOINTS
sda 
├─sda1 
│     vfat   FAT32       2052-EE63                             361.9M    29% /boot 
└─sda2 
      ext4   1.0         465d723a-95cc-43d8-9b4e-35189306417c  841.9G     3% / 
sr0

My `arch.conf`:

~ $ cat /boot/loader/entries/arch.conf
title    Arch Linux
linux    /vmlinuz-linux
initrd   /initramfs-linux.img
options  root=/dev/sda2 rw quiet loglevel=3 udev.log_level=3 nowatchdog mitigations=off modprobe.blacklist=iTCO_wdt transparent_hugepage=madvise

Fstab:

~ $ cat /etc/fstab
/dev/sda2       /               ext4            rw,relatime,commit=60 0 1

/dev/sda1       /boot           vfat            rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro   0 2

Everything seems to work fine except for getting those pacman messages. Does anybody know what causes this?

Re: [Solved] Pacman tells me "Current root is not booted"

https://www.reddit.com/r/archlinux/comm … ot_booted/

https://gitlab.archlinux.org/archlinux/ … =heads#L13

systemd-notify --booted || echo foo

This used to be

systemd_live() {
  is_chrooted
  if [ ! -d /run/systemd/system ]; then
    echo >&2 "  Skipped: Current root is not booted."
    exit 0
  fi
}
stat /run/systemd/system

is ok?

Running this:

systemd-notify --booted || echo foo

gives no output.

The directory `/run/systemd/system` exists, but is empty:

Re: [Solved] Pacman tells me "Current root is not booted"

gives no output

Means systemd should™ consider the current root booted, no idea why that would not work from the hook

pacman -Qikk systemd

Do you get this on all updates or only when updating systemd or the kernel?

I'm not quite sure what the pattern is, but it happens on many packages I tested. For example, on installing emacs:

:: Running post-transaction hooks...
(1/5) Reloading user manager configuration...
  Skipped: Current root is not booted.

Another example is okular:

:: Running post-transaction hooks...
( 1/11) Reloading system manager configuration...
  Skipped: Current root is not booted.
( 2/11) Updating udev hardware database...
( 3/11) Creating temporary files...
( 4/11) Reloading device manager configuration...
( 5/11) Arming ConditionNeedsUpdate...
( 6/11) Updating the MIME type database...
( 7/11) Reloading system bus configuration...
  Skipped: Current root is not booted.

Re: [Solved] Pacman tells me "Current root is not booted"

Edit /usr/share/libalpm/scripts/systemd-hook and add

strace -tt -f -o /tmp/wtf_$$.strace systemd-notify --booted

Install vim tongue and check the generated straces, it seems to be only a convoluted way to check for /run/systemd/system - maybe the strace reveals what's wrong.

A hunch,
please post the full output, including your complete used command line from an example with this strange message.
Please include everything, including your terminal prompt.

I did this, then installed and uninstalled some stuff. Every generated log has only one mention of /run/systemd/system, which looks like this:

Yeah, but the overall strace (notably why it exits non-0) would be more interesting.

On my system pacman is an alias for "sudo pacman". Also, the system is booted normally; no arch-chroot or container...

that didn't fail at all - the hook should™ not complain

My fix for now is to replace the shebang line in /usr/share/libalpm/scripts/systemd-hook with

#!/bin/bash

This seems to be a systemd-boot thing though, because I don't recall GRUB having this problem.

Thank you very much for the help, seth!

Re: [Solved] Pacman tells me "Current root is not booted"

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

You probably also want to file a bug at https://gitlab.archlinux.org/archlinux/ … d/-/issues for the bashism (it's a package bug, the hook is a downstream addition)

Edit:

This seems to be a systemd-boot thing though, because I don't recall GRUB having this problem.

As mentioned, the test was recently changed - maybe coincidentally w/ your bootloader switch.

for the record, this also happens with an out-of-date version of apparmor.d-git (AUR) in enforce mode, solved by rebuilding it
