Installation on arch linux won't start due to missing exiftool

i followed the arch linux installation instructions and during the configuration phase i selected the option to have geolocation data stripped from image uploads, this requires exiftools which are installed:

[root@localhost akkoma]# which exiftool

the akkoma service is stuck starting up because:

23:54:32.153 [error] Elixir.Pleroma.Upload.Filter.Exiftool is specified in list of Pleroma.Upload filters, but the exiftool command is not found
23:54:32.161 [notice] Application pleroma exited: exited in: Pleroma.Application.start(:normal, [])
     ** (EXIT) an exception was raised:

anyone know what’s up?

i develop on arch so it shooooould work

the command checking is done via :os.find_executable Erlang -- os - how are you starting the service? does the PATH provided to akkoma on start inlude /usr/bin/vendor_perl?

Seems like it doesn’t here on Arch Linux using OTP using a systemd service.

ExecStartPre=echo $PATH                                                                                                                                                                                          ExecStart=/opt/akkoma/bin/pleroma start
# my normal PATH √ /home/tpyrope % echo $PATH

This is an intended design by systemd because it heavily discourages modifying PATH during runtime for any services. This also means it does not execute anything under /etc/profile.d/*, which is where one of the necessary Perl shell scripts are ( Ideally you could just set ExecStartPre=/bin/bash -c "/etc/profile.d/", but Arch Linux installs the script’s permissions as 644 which are not executable.

The only proper solution I’ve found is to manually define your path with Environment=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl in the systemd unit (akkoma.service).
