Hallo.
Our distro build team has problems with the new util-linux. util-linux
is one of the low level packages. Now it depends on a two high level
packages with lots of dependencies:
systemd
python
Complete safe bootstrap distro rebuild requires two rebuilds of all
packages in the dependency cycle: one after initial util-linux rebuild
and second after high level dependency rebuild and consequent second
util-linux rebuild.
The build cycle util-linux <-> python is far the largest build cycle. In
case of forthcoming SLES12 it triggers rebuild of 2921 packages!
I was asked to solve this problem, and I created a solution that makes
possible to build:
util-linux stage 1: Everything except stuff that supports systemd and
python-libmount
util-linux stage 2: Stuff that supports systemd (lslogins, logger, uuidd
and fstrim service files) using installed low level stage 1 stuff.
python-libmount: Python bindings only using installed stage 1 stuff.
This is now implemented by a set of sed scripts on top of .am and .ac
sources. But I would like to create more generic solution.
What do you think about one of the following solutions?:
Solution 1:
Modify make system by adding:
--enable-build-stage-1: Distro bootstrap stage 1: Build only code
without systemd and python dependencies.
--enable-build-stage-2: Distro bootstrap stage 2: Build code with
systemd dependencies (even if they are optional). Use installed
instances of libmount, libblkid, libsmartcols and libuuidd, do not
build them in-tree.
--enable-build-stage-3: Distro bootstrap stage 3: Build python-libmount
only. Use installed instance of libmount, do not build them in-tree.
Solution 2:
--enable-build-stage-1 and --enable-build-stage-2 exactly as above.
Split python-libmount into a separate project.
