Some Linux distributions always include a copy of all persistent device
configuration data when updating the initial RAM-disk. This makes
chzdev's persistent device configuration changes ineffective because
device configuration directives applied in the RAM-disk take precedence
over those stored in the root filesystem.
This patch introduces a new build-time switch which allows distributions
to specify that whenever there is a persistent device configuration
change, the RAM-disk is updated automatically.
This feature can be enabled by adding 'ZDEV_ALWAYS_UPDATE_INITRD=1' as
a zdev build option. Where, by default ZDEV_ALWAYS_UPDATE_INITRD is 0.
