Shawn Heisey commented on SOLR-14410:
-------------------------------------
Works on CentOS 7 and AlmaLinux 8. I think it will also work on Ubuntu 20 and
22, and quite possibly even older versions. And it is likely to work on other
Debian derivatives. I'm not sure when Debian/Ubuntu switched to systemd, but I
think it was quite a while ago.
Saw that the service is configured to restart by default. I think this is a
bad default. It should be something that's not difficult to enable, but should
always require explicit admin intervention. If there's any way to make it so
the service looks at the include script to determine that, I think that's the
best way.
I would like to make ALL the defaults currently in the service file
configurable by the include script (and eventually the platform-independent
config file). Basically create a situation where there is rarely any reason
for an end user to modify the service file. If we discourage manual edits of
that file and make everything configurable, a lot of support headaches
evaporate.
I'm on the fence about whether we can switch fully to systemd. The two systems
above where the current installer failed do NOT use systemd ... but Solr STILL
won't install on them even now. I suspect that will be the case for almost any
OS that is not using systemd, but I would like a little more data. It may not
be a bad idea for us to only support out-of-the-box installs on systemd.
