Can I write a plugin that adds to the existing page layout?

I need to display some information at the bottom of every page. In this case, it's the hostname of the server (we have two mirrors). So since each server uses the same Redmine dir, the code needs to be dynamic. I don't want to hack the Redmine code, since I might want to upgrade it in future.

Also, I'm a Ruby newbie, so if someone could give me advice on reading the contents of a file on a hard drive, that would be nice! In this case, I want to read /etc/hostname and show it at the bottom of all pages.

Just a quick reply. I haven't figured out how to make a plugin for this, but I hacked one of the view files...

<div id="footer">
    Powered by <%= link_to Redmine::Info.app_name, Redmine::Info.url %> &copy; \
2006-2010 Jean-Philippe Lang<br />
<%
file = File.new("/etc/hostname", "r")
line = file.gets
%>
    Mirror: <%= line %>
</div>

... if anyone could advise how to move this into a plugin, please let me know!

Take a look at using Hooks. For example, my Google Analyics plugin adds some JavaScript to the bottom of every page. You can easily change this to show the hostname.

Instead of reading /etc/hostname, you should use the appropriate Ruby function which works across systems:

Socket.gethostname

Worked nicely, thanks.
