commit: https://git.buildroot.net/buildroot/commit/?id=4019559de087d9b3a7f54d6b05e388af92b41746 branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master We install a template getty service, and we 'instantiate' it in the default runlevel, using the configured tty. Ideally, packages that provide a getty program would be responsible for installing the corresponding service file. However, to keep consistency with the existing init systems (busybox, systemd, and sysv), so we do provide it from the openrc package itself. OpenRC only acts on the files in a runlevel sub-directory, but the documentation [0] actually suggests that the instance symlink be done in init.d, and then again symlinked into the actual runlevel sub-directory. So, we abide by the rules. Also, to be noted, the getty service file is installed without ensuring that a getty command is available. This again is not unlike other init systems, sysvinit and busybox, which behave the same.
