Despite the easy-sounding task, it appears to be hard to find a suitable package to print line numbers that ignore the automatically generated section/subsection etc. headlines in their counter.
The currently preferred, non-deprecated choice of line-numbering package seems to be lineno, which sadly doesn't have the desired option. My current way of implementing it is calling it using
\usepackage[pagewise, modulo]{lineno}
before the beginning of the document and then calling
\linenumbers
after the table of contents so it doesn't interfere with these.
However, using
\section{Heading}
text longer than 5 lines
results in lineno printing the number 5 next to text line number 4, because it also counts the section heading as a line. Please note that I'd like to refrain from using the linenumbers-environment to manually number every paragraph since my document is quite long.

I am the maintainer of
lineno– thanks for the idea. What about using\Sectionrather than\sectionafterLater, one might "patch"
\sectionaccordingly, maybe even dealing with the optional argument.
