Enable logging via program
By default, Virtualmin configures Apache to log to files in each virtual
server's home directory, under the C<logs> sub-directory. However, if the
domain owner deletes that directory, Apache will be unable to log and will
fail to start! To avoid this, Virtualmin can turn on logging via a wrapper
script which ignores this problem, which contains the damage. The only
cost is a little more memory used by the wrapper programs.
The domains that it
operates on are specified either using the C<--domain> flag (which can appear
multiple times), or C<--all-domains> to turn off logging via script for all
of them.
