When using `ninja -C "$BUILDDIR"`, ninja prints an annoying log
message about entering the directory that cannot be silenced. Let's
manually move in and out of the build directory instead.
Recently, mkosi gained support for specifying an --install-directory
option to save the contents of the install directory between bulids.
By enabling the --only-changed meson install option, meson won't
overwrite the contents of files that haven't changed since the last
build when using --install-directory.
By default, meson install prints a line for every file it installs.
This is verbose and doesn't provide much value. Let's silence the
meson install step to remove this output from the mkosi build step.
The --no-rebuild option removes some additional duplicate output
by the meson install step.
Ubuntu Focal still has meson 0.53.0 so we add a version check and
only use the new feature if the meson version supports it.
Some testcases in test-execute rely on existence of user groups with
certain gids. However, their existence is not universally granted [1].
Although the test could be skipped in their absence and give up testing
some code paths, different approach was chosen -- create dummy groups in
the testing image.
[1] See how systemd-sysusers allocates gids (e.g.
src/test/test-uid-range.c).
Distributions may be build with various configs, e.g. customized
rootprefix. It'd be unmaintanable to have specific mkosi.build for each
supported distro. Hence, make the build script flexible yet distro
oblivious.
These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.
This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.
As it appears meson's test cases nowadays (?) show useful logs for
failing tests anyway, hence there's no need to show them unconditionally
in full every time anymore. Let's hence simplify and drop this.
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
Meson keeps permissions around during the build, so details of how umask
was set when cloning the original git tree will leak all the way to the
installed files in the mkosi image.
So reset the permissions of the files in the copy of the tree before
starting the build.
Also set the umask explicitly.
Tested by creating a mkosi image and booting it on a tree that was
cloned with a umask of 027, confirmed that the *.target files were not
created as world-unreadable anymore.
Using C.UTF-8 (as was done before #7244) breaks Arch Linux, but using
en_US.UTF-8 (after #7244) breaks Debian in our .mkosi/mkosi.debian.
So try to detect which one is available and works, first checking
whether we're already running under a valid UTF-8 locale, then trying
C.UTF-8 and finally en_US.UTF-8.
If we fail to find a valid UTF-8 locale, then fail early, instead of
letting the whole build complete only for Mesos to fail midway through
the `ninja test` step.
Tested on all of mkosi.fedora, mkosi.debian and mkosi.arch.
Fixes: #7238
On Fedora /etc/init.d is a symlink to /etc/rc.d/init.d. Our build
scripts default to /etc/init.d since that is the LSB default. Let's make
sure the build script thus follows the symlink correctly and configures
to path explicitly, since otherwise our build artifacts in $DESTDIR are
incompatible with the setup we actually need for Fedora.
This adds support for the mkosi switch --without-tests that is
introduced by:
https://github.com/systemd/mkosi/pull/122
With this in place doing "mkosi -ifT shell" is the fastest way from a
git clone to a shell within a freshly compiled systemd system.
This adds a build script and a settings file for "mkosi", a tool for putting
together full, bootable disk images for container managers of EFI systems and
VMs.
With these files it's enough to type "mkosi" in the project directory to
generate a bootable Fedora 24 OS image with a version of systemd compiled fresh
from the working tree.
