Functions

func DropPrivileges

func DropPrivileges(username string, group string) error

Changes the processes user and group to that specified in the config.json. The go runtime takes care of all threads (and not only the calling one) executing the underlying systemcall.

func LoadEnv

func LoadEnv(file string) error

Very simple and limited .env file reader. All variable definitions found are directly added to the processes environment.

func SystemdNotifiy

func SystemdNotifiy(ready bool, status string)
