# Building with ghc --make doesn't work properly here because it
# always rebuilds Guestfs.o despite it being up to date. So if you:
#
# * build Guestfs010Load, then build it again, the second time it will
# not be rebuilt.
#
# * build Guestfs010Load, then build Guestfs030Config, then build
# Guestfs010Load again, it will be rebuilt every time.
#
# In the second case, building Guestfs030Config rebuilt Guestfs.o. As
# this is a dependency of Guestfs010Load, Guestfs010Load is now
# unnecessarily out of date.
#
# Because the default target builds all of the above, they will all be
# rebuilt every time.
#
# An obvious choice would be to remove the Guestfs.o dependency, but
# this would potentially result in corruption during a parallel build
# as multiple ghc processes rebuild Guestfs.o simultaneously. I had
# hoped that the solution below would work. It correctly builds
# Guestfs010Load and Guestfs030Config, but Guestfs050LVCreate requires
# additional link options which I haven't been able to work out.

# The solution below isn't ideal. It uses --make and avoids the
