fast boot

[Nandan Appajappa]

Hi thufir,

     The boot chart is showing the link eth0 receiving
the lease from your dhcp server.

     The file /etc/network/interfaces may contain following
lines:

auto eth0
iface eth0 inet dhcp

     which has configuration to receive the lease for link eth0 [ethernet]
from dhcp before your any gui components are loaded.

Possible speedup can be achieved if these lines are commented.
