# first, build docker image with:
# $ podman build -t centos7-build -v <path-to-kernel>:/tmp/linux-kernel \
# 	-f Docker-centos7 .
# this builds and image without ZFS
#
# then use it to build Lustre:
# $ podman run -it
#   --mount type=bind,source=<path-to-kernel>,target=/tmp/kernel \
#   --mount type=bind,source=<path-to-lustre>,target=/tmp/lustre \
#   centos8-build /bin/bash -c "cd /tmp/lustre; sh autogen.sh; \
#   ./configure --with-linux=<path-to-kernel> \
#      --with-linux-obj=<path-to-kernel> --disable-gss \
#      --disable-shared --disable-crypto; make"
#
# TODO:
#  - add ZFS/SPL 0.7 to image
#  - configurable zfs repo, zfs version/tag
#  - move kernel to image
