# Known problems :
#  - genext2fs: couldn't allocate a block (no free space)
#    As genext2fs allocate only one group of blocks, the FS size
#    is limited to 8Mb.

# Update this stuff by hand :
ARCH = i386
# If you are running a cross compiler, you may want to set this
# to something more interesting, like "arm-linux-".
#CROSS = $(ARCH)-linux-
