# You need to have an evms-patched kernel source tree in /usr/src/linux
# to build this.  Either take care of that yourself or do these steps :
#
#   o get a vanilla 2.4.18 kernel and unpack it in /usr/src/linux
#   o ebuild evms-1.0.0-r1.ebuild clean unpack
#   o cd /usr/src/linux
#   o patch -p1 < /tmp/portage/evms-1.0.0-r1/work/evms-1.0.0/kernel/evms-1.0.0-linux-2.4.patch
#   o patch -p1 < /tmp/portage/evms-1.0.0-r1/work/evms-1.0.0/kernel/evms-linux-2.4.18-common-files.patch
#   o patch -p1 < /tmp/portage/evms-1.0.0-r1/work/evms-1.0.0/kernel/linux-2.4.18-VFS-lock.patch
#
# The third patch isn't totally required.  Now configure your kernel
# and select the evms features that you want.  If you plan on using
# an evms volume on your /boot partition then you'll need to use the
# included patch against lilo-22.2 in the same directory as above.
# Please see their homepage for further information and details.
