Introducing ostree-grub-generator ostree-grub-generator can be used to customize the generated grub.cfg file. Compile time decision ostree-grub-generator vs grub2-mkconfig can be overwritten with the OSTREE_GRUB2_EXEC envvar - useful for auto tests and OS installers. Why this alternative approach: 1) The current approach is less flexible than using a custom 'ostree-grub-generator' script. Each system can adjust this script for its needs, instead of using the hardcoded values from ostree-bootloader-grub2.c. 2) Too much overhead on embedded to generate grub.cfg via /etc/grub.d/ configuration files. It is still possible to do so, even with this patch applied. No need to install grub2 package on a target device. 3) The grub2-mkconfig code path has other issues: https://bugzilla.gnome.org/show_bug.cgi?id=761180 Task: https://bugzilla.gnome.org/show_bug.cgi?id=762220 Closes: #228 Approved by: cgwalters

# Makefile for boot module
Add --with-dracut This installs a Dracut module which parses the ostree= kernel command line argument, and if given, sets up the OS/ at /sysroot, which systemd's switch-root then moves into. This only works if dracut is configured to use systemd itself.

build: Introduce --with-dracut=yesbutnoconf It's actually just easier for build systems (e.g. rpm-ostree) using dracut to use `--add ostree` rather than indirecting through the conf file. This makes it easier for yum-managed systems to install ostree without side effects. Closes: #279 Approved by: gatispaeglis

build: Move grub2-15_ostree back to pkglibexecdir It's not quite namespaced enough to have `/usr/libexec/grub2-15_ostree`, and the Fedora spec file expects things in `/usr/libexec/ostree`. Changing the spec file would be annoying as we'd need conditionals. Closes: #249 Approved by: gatispaeglis

libostree: Add initial GRUB2 support In this approach, we drop a /etc/grub.d/15_ostree file which is a hybrid of shell/C that picks up bits from the GRUB2 library (e.g. the block device script generation), and then calls into libostree's GRUB2 code which knows about the BLS entries. This is admittedly ugly. There exists another approach for GRUB2 to learn the BLS specification. However, the spec has a few issues: https://www.redhat.com/archives/anaconda-devel-list/2014-July/msg00002.html This approach also gives a bit more control to the admin via the naming of the 15_ostree symlink; they can easily disable it: Or reorder the ostree entries ahead of 10_linux: Also, this approach doesn't require patches for grub2, which is an issue with the pressure to backport (rpm-)OSTree to EL7.

# We're using our internal generator
Move ostree-* executables to /usr/lib/ostree Why not to use libexecdir? Because this directory does not exist on some distros or paths between distros varies. There are several reasons why a well known path is prefered, for example when generating a kernel command line: init=${ostree}/usr/lib/ostree-boot/ostree-prepare-root In addition this saves us some typing in a console when wanting to access the "ostree" cmd line.
