Looks fine to me - Exim's flexibility strikes again :-)

A couple of observations:

- All pipe and file deliveries will happen under the 'exim' user - you
should be sure this is what you want

- You might want to have a domains= option on that router to make sure it
only fires on domains which you have an alias file for, otherwise strange
errors will happen when it tries to handle a domain which doesn't have a
file. You could automate this with a small change to your file layout and a
dsearch lookup:

 system_aliases:
    driver = redirect
    domains = dsearch;/etc/virtaliases
    allow_fail
    allow_defer
    data = ${lookup{$local_part}lsearch*{/etc/virtaliases/$domain}}
    user = exim
    file_transport = address_file
    pipe_transport = address_pipe


or like this:

 system_aliases:
    driver = redirect
    allow_fail
    allow_defer
    require_files = /etc/aliases.$domain
    data = ${lookup{$local_part}lsearch*{/etc/aliases.$domain}}
    user = exim
    file_transport = address_file
    pipe_transport = address_pipe


Either one will cause the router to pass if the file doesn't exist.
