Incorrect page numbering with different numbering styles

Question

I have an issue with my page numbering. I want the first pages of my document number in "roman" style and the rest "arabic". I have done this with the \pagenumbering command, which actually works quite well. The only problem is, when I switch to arabic page numbering before the chapter "Introduction" it, kind of recursively, also applies for the preceding chapter "List of Abbreviations", what should not be the case.

 \documentclass[12pt]{report}
    \usepackage[a4paper, width=159mm, top=25mm, bottom=20mm]{geometry}
    \usepackage[utf8]{inputenc}
    \usepackage{graphicx}
    \usepackage{url}
    \usepackage[colorlinks=false, pdfborder={0 0 0}]{hyperref}
    \usepackage{etoolbox}
    \usepackage{multirow}
    \usepackage{tablefootnote}
    \usepackage{footnote}
    \usepackage{tabularx}

\pagenumbering{roman}

\begin{document}
\input{partials/titlepage}
\chapter*{Document version}
\addcontentsline{toc}{chapter}{Document version}
\input{partials/document_versions}
\chapter*{About this Document}
\addcontentsline{toc}{chapter}{About this Document}
\input{partials/purpose_of_this_paper}
\tableofcontents

\addcontentsline{toc}{chapter}{List of Figures}
\listoffigures
\chapter*{List of Abbreviations}
\addcontentsline{toc}{chapter}{List of Abbreviations}
\input{partials/list_of_abbreviations}

\pagenumbering{arabic}
\chapter{Introduction}
\input{partials/introduction}
\chapter{System}  
\input{partials/system}
\chapter{Component}

Answer 1

The \pagenumbering command applies to the current page. Issuing before \chapter{Introduction} means that it applies to the page you are on at that time, in this case the List of Abbreviations. Instead you can move \pagenumbering it to just after \chapter{Introduction} to get the new numbering to start on that page.

Had you been using the book class instead of report, you could have used the division commands \frontmatter, \mainmatter and \backmatter to effect exactly the changes you are after.
