- actually, PID files come from sysvinit only starting services and not keeping track of them afterwards. sysvinit is every bit as flexible as upstart or systemd...but its design criteria is much simpler, from a simpler age. PID files exist to help other tools (or the admin on the command line) keep track of and manage daemons after they've been started.cas– cas2015-11-10 01:49:57 +00:00Commented Nov 10, 2015 at 1:49

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
