We only create this directory while installing the package. If a user
deletes /var/log then they will lose access to the web UI.

the thing that only works as root is the chown, not all of this..

but anyway, it would be much easier to read and have better semantics if
we switch to
if root {
my $uid = ..
my $gid = ..
mkdir(..)
chown(..) || warn ...
mkdir(..)
chown(..) || warn ...
}
which has the added benefit of resetting the ownership to the right
value on reboot/service start, so fixes another potential issue (at the
cost of two unconditional syscalls).
