After recently upgrading from www-apps/grafana-bin-9.3.6 to www-apps/grafana-bin-9.4.7 and restarting the service via the OpenRC init script, Grafana failed to start.

Expected behavior is for everything to work after a Grafana upgrade and the new Golang binary simple will start back up.

After digging a little deeper and invoking the same binary that /etc/init.d/grafana does locally on Funtoo Linux, /usr/bin/grafana-server in this scenario, I found the issue:

grafana-server
Error locating grafana: exec: "grafana": executable file not found in $PATH

It looks like the new version of Grafana is expecting another Golang binary to be present locally.

Doing some even deeper digging into the upstream tarball I found the root cause:

wget https://dl.grafana.com/oss/release/grafana-9.4.7.linux-amd64.tar.gz
tar tzvf grafana-9.4.7.linux-amd64.tar.gz | grep bin
drwxr-xr-x root/root         0 2023-03-16 17:03 grafana-9.4.7/bin
-rwxr-xr-x root/root 134009568 2023-03-16 17:03 grafana-9.4.7/bin/grafana
-rwxr-xr-x root/root   1473264 2023-03-16 17:03 grafana-9.4.7/bin/grafana-cli
-rw-r--r-- root/root        33 2023-03-16 17:03 grafana-9.4.7/bin/grafana-cli.md5
-rwxr-xr-x root/root   1473264 2023-03-16 17:03 grafana-9.4.7/bin/grafana-server
-rw-r--r-- root/root        33 2023-03-16 17:03 grafana-9.4.7/bin/grafana-server.md5
-rw-r--r-- root/root        33 2023-03-16 17:03 grafana-9.4.7/bin/grafana.md5

So it looks like the autogen ebuild template needs to be updated to include another dobin line to include the new bin/grafana binary, which can go on line 45 of kit-fixups/net-kit/curated/www-apps/grafana-bin/templates/grafana-bin.tmpl
