ArchLinux Pi-hole is not officially supported by Pi-hole project. In case of bugs and malfunctions please DO NOT file a report upstream.

First of all check if the wiki (https://wiki.archlinux.org/index.php/Pi-hole) can help then ask here for assistance and tips.
When it will be excluded that the problem does not depend on ArchLinux we will file a bug upstream.

Figured it out. It's libvirtd.service that hates pihole-FTL.service trying to be dnsmasq once again and overwrites/changes the ownership of the files in /dev/shm/FTL* to root:root. It does look like a bug with pihole. Because the default dnsmasq surely does not use user "pihole" and I assume it more likely uses "root" (not 100% sure, but ... more likely than pihole). So when pihole tries to be drop-in replacement for dnsmasq and creates some extra user to run as and then fails when some other process that heavily depends on dnsmasq and runs dnsmasq(pihole in disguise) as root and overwrites something and pihole itself then crashes because it can't anymore access his own files... kinda screams for pihole inadequacy.

After running a while, all the FTL-* files in /dev/shm/ directory turned to root:root again and pihole-FTL.service failed again.

@deemon: Pi-hole version is -15.2.1 (Latest: v5.2.1) is related to /opt/pihole/version.h

...
# Variables
DEFAULT="-1"
COREGITDIR="/etc/.pihole/"
WEBGITDIR="/srv/http/pihole/admin/"
...
 # Local FTL btranch is stored in /etc/pihole/ftlbranch
if [[ "$1" == "FTL" ]]; then
    branch="$(pihole-FTL branch)"
    else
        cd "${directory}" 2> /dev/null || { echo "${DEFAULT}"; return 1; }
        branch=$(git rev-parse --abbrev-ref HEAD || echo "$DEFAULT")
fi
...

Replacing DEFAULT="-1" with DEFAULT="" fixes this.

libvirtd.service complains about unparsable dnsmasq version number.

$ pihole -v
  Pi-hole version is -15.2.1 (Latest: v5.2.1)
  FTL version is 5.3.2 (Latest: v5.3.2)

not quite sure the version should be -15.2.1

After updating it stop starting. Apparently pihole-FTL.service started failing to start.

so... I went to /dev/shm and moved all the FTL-* files to backup folder and it started afterwards fine. Observed that all the previous files now in backup folder are root:root, whereas the new created files are all pihole:pihole.

@setboolean yes it's true! missed that querytypes is now extern...
and no more warnings!!! nice for a patch release...
thanks for reporting.

xyzabc123 commented on 2020-12-03 09:35 (UTC)

@max.bra It seems patching HARDENING_FLAGS and EXTRAWARN is no longer necessary.

max.bra commented on 2020-12-02 08:43 (UTC)

@meijin lsof is in server now, thanks for reporting!

meijin commented on 2020-12-02 07:51 (UTC)

I think lsof is missing as a dependency:

> pihole -g
....
  [✓] Cleaning up stray matter

/usr/bin/pihole: line 268: lsof: command not found
