What init system do Amazon Linux AMI instances use on Amazon Lightsail?
The AWS documentation says to use "User Data" scripts, which doesn't apply to Lightsail I don't think.
I know that it's based on RedHat, which I understood to use systemd, but there's no
/etc/init, and the files in
/etc/init.d/ don't end in
.conf (or look like upstart files), so it's not upstart, but yet
/etc/init/rc.conf makes mention of upstart.
I know there were about a hundred different systems before upstart. I think Sys V Init is the classic... I don't even remember what Sys V Init looks like. Is that what it is?
It's got all the
/etc/rcx.ds, a prime suspect for sysvinit, and the
/etc/init.d/ files look like sysvinit, and 'chkconfig' is installed, but yet the comments in
/etc/inittab again mention upstart and say that the config is ignored... I'm so confused.
Is it some "special" version of
sysvinit? Or are the comments wrong?
