DESCRIPTION = "Aufs is a stackable unification filesystem such as Unionfs, which unifies several directories and provides a merged single directory."

# We do not create the manpage for aufs because we do not install it anyway.
# If you want to have the manpage created you will need to add host cc to
# the makefile else it will fail to crosscompile.
# See http://svn.exactcode.de/t2/trunk/package/filesystem/aufs/compile.patch.cross
# as an example how this could be done.

# We need to check the architecture and the kernel version to
# configure properly lokal.mk. We ignore the export CONFIG_AUFS_STAT option.
# If you want to have CONFIG_AUFS_STAT enabled you have to add some other ARCH checks.
# Debian does not enable CONFIG_AUFS_STAT for arm.
# We disable CONFIG_AUFS_SYSAUFS for arm because arm does not know about cmpxchg.
# If you want this feature enabled you have to define it.
# I suggest you to read http://osdir.com/ml/linux.kernel.tracing/2006-12/msg00020.html
