Debian specific. You could probably change the shell to /bin/false

This is normal in any Debian setup and you should leave it as is.

This is also normal in Debian setups. However, you can change it if you do
not feel it's appropiate.

For some explanation regarding Tiger's issues see: tigexp.

Templates are easy to do, just copy any report from a module (available
under /var/log/tiger) into /etc/tiger (or /var/log/tiger but it's
deprecated) changing the .out prefix to .template. Remove all the lines
that you *want* to be reported about. The lines that are kept in the
template will *never* be reported.

AFAIK This is documented in tiger(8) (but maybe it's only in the 3.0
version in unstable). Also, keep in mind that the default behavior of
Tiger will be to *only* email you the changes after a given module has
been run (like if the previous run was the template for the next). This
makes it easier to detect changes.

Hope you like it!
