":" and "." in interface name.

[Rakotomandimby Mihamina <mihamina@gulfsat.mg>]

Hi all
this is a sample of one interfaces file I found.

[...]
auto eth0:17
iface eth0:17 inet static
  [...]
auto eth0:18
iface eth0:18 inet static
  [...]
auto eth1.2
iface eth1.2 inet static
  [...]
auto eth1.3
iface eth1.3 inet static
  [...]
auto eth1.4
iface eth1.4 inet static
  [...]

I usually use ":" to make aliases. Has "." a special meaning?
