Add ostree-switch-root here Merge the code from ostree-init; now that we're back to targeting an initramfs (dracut), we don't need to statically link the binary, so there's no strong reason to have a separate module.

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.

build: clean up ostree-remount if building without systemd This is necessary for "make distcheck" on Travis-CI. Signed-off-by: Simon McVittie <simon.mcvittie@collabora.co.uk> Closes: #600 Approved by: cgwalters

# It is built anyway as a side-effect of having the symlink in tests/,

build: Add --enable-triggers-only For bootstrapping gnome-ostree, we need to install the triggers early on, before we actually build the real ostree binary.

dracut: Add ostree-remount Linux creates a copy of the soure mount flags when creating a bind mount; if the source is read-only, then the bind mount is. The problem is that systemd will remount the rootfs read/write, but each mount (/home, /var etc.) will still be read-only. We need to remount every bind mount except for /usr to read-write too. This only "worked" with the old ostree-switch-root because it effectively force mounted the rootfs read-write always, ignoring the "ro" flag.

ostree-prepare-root: Allow building statically with musl If the `--with-static-compiler=musl-gcc` configure flag is given. ostree-prepare-root can be used as init in a system without a populated /lib. To support this use case we need to link statically as we will be unable to locate libc.so at run time if it's not installed in /lib. We support building ostree-prepare-root with a different compiler to the rest of ostree so we can use musl rather than glibc. This reduces the size of the executable significantly: from ~700K -> ~30K. We have to use `_SCRIPTS` here to get autotools to install this as an executable but without generating rules to make it itself which we have specified manually. See https://lists.gnu.org/archive/html/help-gnu-utils/2007-01/msg00007.html for advice on using autotools in this manner. Closes: #477 Approved by: cgwalters
