In the production case since we used `daemon()` our stderr is `/dev/null`¹
there's not much use in logging errors from `FITHAW` or `exit(1)`, and doing so
breaks the test suite which checks the return from `waitpid()`. There's nothing
we can really do if `FITHAW` fails, and in most of those cases `EINVAL`,
`EOPNOTSUPP`, we *shouldn't* do anything anyways.
¹ Though perhaps we should set up the systemd journal, but let's not
go there right now.

I added `waitpid()`, but that didn't actually help because we were
`daemon()`izing. Don't daemonize if we're testing so that we can `waitpid()`.

fix it.
While here, actually check the return value from `waitpid()` just in case

various uses of G_IO_ERROR_FAILED, and one instance of
G_IO_ERROR_NOT_FOUND (for which some code in ot-builtin-show.c had to be

The use of a separate error domain allows failures in GPG operations to

When returning results from finding repos, set gpg-verify-summary=false
in their configs, since any pulls from such remotes will necessarily
involve collection IDs, and hence should be using the unsigned summary
support. In the intended deployment mode for P2P transmission of OSTree
refs, summaries *cannot* be signed, so setting gpg-verify-summary=true
would cause all the pulls to fail.
The unsigned summary support is the move of repository metadata from
the summary file (not spliceable) to the well-known ostree-metadata ref
(spliceable, as it can exist for multiple collection IDs in the same
repository).

XFS doesn't flush the journal on `syncfs()`. GRUB doesn't know how to follow the
XFS journal, so if the filesystem is in a dirty state (possible with xfs
`/boot`, extremely likely with `/`, if the journaled data includes content for
`/boot`, the system may be unbootable if a system crash occurs.
Fix this by doing a `FIFREEZE`+`FITHAW` cycle. Now, most people
probably would have replaced the `syncfs()` invocation with those two
ioctls. But this would have become (I believe) the *only* place in
libostree where we weren't safe against interruption. The failure
mode would be ugly; nothing else would be able to write to the filesystem
until manual intervention.
The real fix here I think is to land an atomic `FIFREEZETHAW` ioctl
in the kernel. I might try a patch.
In the meantime though, let's jump through some hoops and set up

(Note this PR was reverted in <https://github.com/ostreedev/ostree/pull/902>;
this version should be better)
Using `${sysroot}` to mean the physical storage root: We don't want to write to
`${sysroot}/etc/ostree/remotes.d`, since nothing will read it, and really
`${sysroot}` should just have `/ostree` (ideally). Today the Anaconda rpmostree
code ends up writing there. Fix this by adding a notion of "physical" sysroot.
We determine whether the path is physical by checking for `/sysroot`, which
exists in deployment roots (and there shouldn't be a `${sysroot}/sysroot`).
In order to unit test this, I added a `--sysroot` argument to `remote add`.
However, doing this better would require reworking the command line parsing for
the `remote` argument to support specifying `--repo` or `--sysroot`, and I
didn't quite want to do that yet in this patch.
This second iteration of this patch fixes the bug we hit the first time;
embarassingly enough I broke `ostree remote list` finding system remotes.
The fix is to have `ostree_repo_open()` figure out whether it's the same
as `/ostree/repo` for now.
Down the line...we might consider having the `ostree remote` command line itself
instatiate an `OstreeSysroot` by default, but this maximizes compatibility; we
just have to pay a small cost that `ostree` usage outside of that case like
`ostree static-delta` in a releng Jenkins job or whatever will do this `stat()`
too.

This came up in <https://github.com/ostreedev/ostree/pull/982>; when
we added more direct local importing, we did it synchronously.
This was actually quite a regression when doing local pulls between different
modes; in particular between a bare mode and `archive`, as we were suddenly
doing gzip {de,}compression in the main thread.
Down the line actually...a simpler fix is probably to change things so that the
local path is really only used when we know we can hardlink; everything else
would go though the fetcher codepath but with `file://`.
But this isn't a lot more code, and the speed/interactivity win is large.
Note we're only doing content async with this patch. We could do metadata as
well; we have the object already local. But the metadata code path is messier,
and metadata objects are smaller.
Another area where this comes up is that in e.g. Fedora releng, most operations
talk to a NetApp via NFS. So this has the classic network filesystem problem
that operations that are normally cheap like `stat()` can actually have
nontrivial latency. Doing as much as possible in threads is better there too.

Some of the Jenkins jobs for Fedora Atomic Host broke after updating
to 2017.7, and it turns out that we regressed handling unreadable

Now there are better fixes here; we should probably delete it and create it
during the config merge if it doesn't exist. In general, having secret files in
ostree really isn't supported, so it doesn't make sense to include them.
But let's fix this regression - when operating as an unprivileged user we don't

There's lots of mechanically replacing `OtTmpFile` with `GLnxTmpfile`;

The commit codepath separates those as `_ostree_repo_commit_path_final()` and
`_ostree_repo_commit_tmpf_final()`. A nice aspect of all of this is that they
both *consume* the temporary on success. This avoids an extra spurious
`unlink()` call.
One of the biggest bits of code motion is in `commit_loose_regfile_object()`,

Computing download/storage size for `archive` pulls is hard; there's
`OSTREE_REPO_COMMIT_MODIFIER_FLAGS_GENERATE_SIZES` which was from a
pre-static-deltas effort by Endless, but we aren't currently making use of this
much.
Static deltas were designed to solve this problem; we have the total
uncompressed size. Let's check free space before doing a delta pull.

The `OstreeRepoContentBareCommit` struct was basically an `OtTmpFile`, so let's
make it one. I moved the "convert to `GOutputStream`" logic into the callers,
since that bit can't fail; it makes the implementation much simpler since we can
just return the result of `ot_open_tmpfile_linkable_at()`.
Prep for `GLnxTmpfile` porting.

The pull code also could make use of this in both the metadata and content
paths. I changed it to own the tempfile malloc (just like `GLnxTmpFile`), since
there's no reason to have different lifetimes for the filename and the file, and
that way we only have one variable rather than two.
The content path turns out to be a special case though, where
at least for mirroring archives, we directly pass the file *path*
down into `_ostree_repo_commit_loose_final()`.
This is prep for `GLnxTmpFile` porting.

The variables here were duplicative; we don't need two booleans to distinguish
between symlinks and regular files. What we do need to handle is the "physical"
state versus the "object" state. Symlinks objects are stored as regular files in
`bare-user` and `archive`.
Prep for more cleanup.
