# ARM patch -- the LSI SCSI driver inside QEMU doesn't
# like hal:
# Works in QEMU 0.10.1 with Linux 2.6.28.9 -- for a while.
# Then the problem resurfaced when I was doing some disk I/O --
# so, repatched :-(
# However, HAL works fine on the Marvell SheevaPlug (real H/w not emulation)
# so I think we can leave HAL patched out of the Versatile platform for good
# since at least we can test the HAL package on the SheevaPlug now.

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
