[PATCH V4] base-files: provide a mechanism to skip creation of the hostname file

[PATCH V4] base-files: provide a mechanism to skip creation of the hostname file

[Mark Hatle]

From: Mark Asselstine <mark.asselstine@windriver.com>

The existence of a /etc/hostname file causes any hostname provided on
the kernel command line or via dhcp to be overwritten by the
initscripts 'init.d/hostname.sh'. This change allows you to set a
value of "" for 'hostname' which will skip the creation of the
/etc/hostname file by the base-files package.
