Usage: $(basename "${BASH_SOURCE[0]}") [-h] [-v] [-r] -s /opt/onedev-base -d /opt/onedev

Upgrades (or creates) a OneDev installation using the official upgrade script.

The OneDev AUR package keeps the latest version of the application in
/opt/onedev-base and uses that to upgrade the live installation at /opt/onedev.
These directories are used by default unless specified via the -s and -d
parameters.

This script will not upgrade the system if the systemd service is running. If
you want to automatically stop and restart the systemd service then pass the -r
flag.

Available options:

-h, --help      Print this help and exit
-v, --verbose   Print script debug info
-s, --source    Source directory containing newer version
-d, --dest      Destination directory to be upgraded
-r, --restart   Stop and restart OneDev if systemd service is active
