pkgx and systemd unit

Start with the PermissionDenied path in src/utils/execve.ts and its caller in src/modes/x.ts, then reproduce the reported garm.service invocation under the shown systemd environment. Trace which executable or path fails and use the journal output to confirm the cause; done means the permission failure is explained and a verified fix or clear diagnostic is available.

Hi,

i try to use pkgx in a systemd unit for "GitHub Actions Runner Manager"

ubuntu@github-actions-runner-manager:~$ sudo cat /etc/systemd/system/garm.service

[Unit]
Description=GitHub Actions Runner Manager (garm)
After=multi-user.target

[Service]
Type=simple
User=_garm
Group=_garm
RuntimeDirectory=garm
RuntimeDirectoryPreserve=yes
WorkingDirectory=%t
ExecStart=/usr/local/bin/pkgx --verbose=2 +garm^${GARM_VERSION} garm -config ${GARM_CONFIG_PATH}
ExecReload=/bin/kill -HUP $MAINPID
Restart=always
RestartSec=5s

[Install]
WantedBy=multi-user.target

ubuntu@github-actions-runner-manager:~$ sudo cat /etc/systemd/system/garm.service.d/local.conf

[Service]
Environment="DEBUG=1"
Environment="PKGX_DIR=/var/run/garm/.pkgx"
Environment="PATH=/usr/local/bin:${PATH}"
Environment="GARM_VERSION=0.1.4"
Environment="GARM_CONFIG_PATH=/etc/garm/config.toml"

ubuntu@github-actions-runner-manager:~$ ls -alFh /var/run/garm/
total 0
drwxr-xr-x  3 _garm _garm   60 Jun 27 11:53 ./
drwxr-xr-x 32 root  root  1.1K Jun 27 11:53 ../
drwxr-xr-x  4 _garm _garm   80 Jun 27 11:53 .pkgx/

i got the following Permission error and do not have enough info to troubleshoot. any idea?

ubuntu@github-actions-runner-manager:~$ journalctl -fu garm
