#
# initrd, building the initrd.sq file.
#
# this is a bit special than most other .mk files since it will always 
# build the file, regardeless the exsistence of a initrd.sq file.
#
# The reasons are that we don't know which type of initrd.sq file we have, 
# we do make two of'em here already (IDE and basic) and since the building
# of the images, initrd.sq and add.bz2 are separate from the rest, you never
# really know when to build or not. 
#
# So, this is being on the safe side.
