Expand description
Detaching from the terminal, for -f.
This has to run before the tokio runtime is created: fork(2) does not
carry threads into the child, so a runtime built beforehand would be left
with worker threads that no longer exist.
autossh calls daemon(3) (autossh.c:448). macOS deprecates that function, so
rash performs the same steps by hand — daemon(0, 0) means “do chdir to /”
and “do close the standard descriptors”.
Functions§
- daemonize
- Fork twice, start a new session, move to
/, and point the standard descriptors at/dev/null.
