Enable user to specify that a device should be configured early, that is
during the initial RAM-disk boot phase. This may be necessary, e.g. to
override auto-configuration for a device which is also applied during
that boot phase. It may also be used to manually specify devices that
are required to access the root file system, such as networking devices.
Users can mark devices as requiring early configuration by specifying
a value of 1 for the newly added internal attribute zdev:early:
# chzdev dasd-eckd 0.0.1234 -p zdev:early=1
This can be changed back by removing the attribute setting, or by
setting the attribute value to 0:
# chzdev dasd-eckd 0.0.1234 -p -r zdev:early
or
# chzdev dasd-eckd 0.0.1234 -p zdev:early=0
