The general consensus: it will work. I will have to make minor midifications
to make it working at boot time:

1. place the address or hostname in /etc/hostname.le0:1 file;
   in case of hostname, place address and hostname in /etc/hosts
2. place a netmask in /etc/netmasks file

this will allow /etc/init.d/rootusr read the /etc/hostname.le0:1 file
and set up interface at boot time. To make this station act as a router
eliminate /etc/defaultrouter file (and reboot).

3. may want to add "up" flag at the end of ifconfig line (in case of manual
   configuration). Or do ifconfig le0:1 up after assigning original command.
   In case of manual configuration no need for reboot (unless need a router).
