When graphroot is set by the user, we should set libpod's static
directory to a subdirectory of that by default, to duplicate
previous behavior.

Ensure that the directory where we will create the Podman db
exists prior to creating the database - otherwise creating the DB
will fail.

When validating fields against the DB, report more verbosely the
name of the field being validated if it fails. Specifically, add
the name used in config files, so people will actually know what
to change it errors happen.

Ensure we don't break the unit tests by creating a locks
directory (which, prior to the last commit, would be created by
BoltDB state init).
Signed-off-by: Matthew Heon <mheon@redhat.com>
We already create the locks directory as part of the libpod
runtime's init - no need to do it again as part of BoltDB's init.

Previous commits ensured that we would use database-configured
paths if not explicitly overridden.
However, our runtime generation did unconditionally override
storage config, which made this useless.
Move rootless storage configuration setup to libpod, and change
storage setup so we only override if a setting is explicitly
set, so we can still override what we want.

If the DB contains default paths, and the user has not explicitly
overridden them, use the paths in the DB over our own defaults.
The DB validates these paths, so it would error and prevent
operation if they did not match. As such, instead of erroring, we
can use the DB's paths instead of our own.

To configure runtime fields from the database, we need to know
whether they were explicitly overwritten by the user (we don't
want to overwrite anything that was explicitly set). Store a
struct containing whether the variables we'll grab from the DB
were explicitly set by the user so we know what we can and can't
overwrite.
This determines whether libpod runtime and static dirs were set
via config file in a horribly hackish way (double TOML decode),
but I can't think of a better way, and it shouldn't be that
expensive as the libpod config is tiny.

Previously, we implicitly validated runtime configuration against
what was stored in the database as part of database init. Make
this an explicit step, so we can call it after the database has
been initialized. This will allow us to retrieve paths from the
database and use them to overwrite our defaults if they differ.

When we configure a runtime, we now will need to hit the DB early
on, so we can verify the paths we're going to use for c/storage are correct.
Signed-off-by: Matthew Heon <mheon@redhat.com>
When we create a Libpod database, we store a number of runtime
configuration fields in it. If we can retrieve those, we can use
them to configure the runtime to match the DB instead of inbuilt
defaults, helping to ensure that we don't error in cases where
our compiled-in defaults changed.

we need to inherit this change from runc.
commit 869add33186caff4a22e3e11a7472a2d48d77889:
rootless: fix running with /proc/self/setgroups set to deny
This is a regression from 06f789cf26774dd64cb2a9cc0b3c6a6ff832733b
when the user namespace was configured without a privileged helper.
To allow a single mapping in an user namespace, it is necessary to set
/proc/self/setgroups to "deny".
For a simple reproducer, the user namespace can be created with
"unshare -r".

Currently we are mounting /dev/shm from disk, it should be from a tmpfs.
User Namespace supports tmpfs mounts for nonroot users, so this section of
code should work fine in bother root and rootless mode.

Don't try to argparse command-line arguments on the right-hand
side of the image; those are intended for the container command:
pypodman create fedora ls -l
pypodman run fedora find / -name foo
pypodman run fedora bash -c 'echo hi'
If/when `pypodman exec` gets implemented, it should use this too.

Whe running unittests on newer golang versions, we observe failures with some

with https://github.com/opencontainers/runc/pull/1807 we moved the
systemd notify initialization from "create" to "start", so that the
OCI runtime doesn't hang while waiting on reading from the notify
socket. This means we also need to set the correct NOTIFY_SOCKET when
start'ing the container.
