Initial fs-verity support
Using fs-verity is natural for OSTree because it's file-based,
as opposed to block based (like dm-verity). This only covers
files - not symlinks or directories. And we clearly need to
have integrity for the deployment directories at least.
Also, what we likely need is an API that supports signing files
as they're committed.
So making this truly secure would need a lot more work. Nevertheless,
I think it's time to start experimenting with it. Among other things,
it does *finally* add an API that makes files immutable, which will
help against some accidental damage.
This is basic enablement work that is being driven by
Fedora CoreOS; see also https://github.com/coreos/coreos-assembler/pull/876

build: fix systemd feature advertisement
17db0f15a798 ("configure: add option for libsystemd") exposed
--without-libsystemd to allow systemd to be disabled even if the systemd
pkgconfig script was present, introducing a new variable
with_libsystemd; there are now three, almost identical variables:
- with_libsystemd [yes, no, maybe] - controlled by --without-libsystemd,
resolved into yes/no by the initial checks
- have_libsystemd [yes, no, <undefined>] - only set if with_libsystemd
is yes/maybe, otherwise undefined
- with_systemd [yes, <undefined>] - yes if have_systemd is yes,
otherwise undefined
with_systemd is the earliest variable and was previously set by a set of
checks for dracut and mkinitcpio. These checks were changed for a
systemd check in 9e2763106be0 ("lib: Use sd_journal directly
(optionally)"). This commit also introduced BUILDOPT_LIBSYSTEMD, which
will always match BUILDOPT_SYSTEMD.
Fix the confusion by removing with_systemd which will always be yes when
with_libsystemd=yes, or undefined if with_libsystemd=no. We can ignore
the with_libsystemd=maybe case because it will always be resolved into
yes/no before with_systemd is set.
And replace all uses of BUILDOPT_SYSTEMD with BUILDOPT_LIBSYSTEMD, since
they again always match.
This fixes both the advertised features and the summary output when
systemd is disabled by using with_libsystemd which is always defined.

ostree/trivial-httpd: Fix --autoexit with --daemonize and --log-file
When --autoexit is used with --daemonize and --log-file, the program
never exits when the root directory is deleted. I believe what happens
is that g_file_new_for_path triggers the glib worker context to be
started to talk to GVfs. Once the program forks, the parent exits and
the thread iterating the worker context is gone. The file monitor then
never receives any events because the inotify helper also runs from the
worker context.
Move the fork earlier just after parsing and validating the command line
arguments. In order to handle setup errors in the child, a pipe is
opened and the parents waits until the child writes a status byte to it.
If the byte is 0, the parent considers the child setup successful and
exits and the child carries on as a daemon. Notably, the child doesn't
reopen stderr to /dev/null until after this so that it can send error
messages there.

Support mounting /sysroot (and /boot) read-only
We want to support extending the read-only state to cover `/sysroot`
and `/boot`, since conceptually all of the data there should only
be written via libostree. Or at least for `/boot` should *mostly*
just be written by ostree.
This change needs to be opt-in though to avoid breaking anyone.
Add a `sysroot/readonly` key to the repository config which instructs
`ostree-remount.service` to ensure `/sysroot` is read-only. This
requires a bit of a dance because `/sysroot` is actually the same
filesystem as `/`; so we make `/etc` a writable bind mount in this case.
We also need to handle `/var` in the "OSTree default" case of a bind
mount; the systemd generator now looks at the writability state of
`/sysroot` and uses that to determine whether it should have the
`var.mount` unit happen before or after `ostree-remount.service.`
Also add an API to instruct the libostree shared library
that the caller has created a new mount namespace. This way
we can freely remount read-write.
This approach extends upon in a much better way previous work
we did to support remounting `/boot` read-write.

we'd still get events from it if subsequent operations iterated the
context.
This patch is mostly a revert of #1954, except that we still keep a ref
on the `GSource`. That way it is always safe to destroy it afterwards.

bootloader: Add a zipl bootloader backend
zipl is a bit special in that it parses the BLS config files
directly *but* we need to run the command to update the "boot block".
Hence, we're not generating a separate config file like the other
backends. Instead, extend the bootloader interface with a `post_bls_sync`
method that is run in the same place we swap the `boot/loader` symlink.
We write a "stamp file" in `/boot` that says we need to run this command.
The reason we use stamp file is to prevent the case where the system is
interrupted after BLS file is updated, but before zipl is triggered,
then zipl boot records are not updated.
This opens the door to making things eventually-consistent/reconcilable
by later adding a systemd unit to run `zipl` if we're interrupted via
a systemd unit - I think we should eventually take this approach
everywhere rather than requiring `/boot/loader` to be a symlink.
