commit b3014c1c69d5870104aa45f7caae7af041094171 changed
GetRootlessRuntimeDir() to return an empty string for root, so that
its value is not exported as XDG_RUNTIME_DIR, and other programs like
crun can use a better default.
Now GetRootlessPauseProcessPidPath() uses homedir.GetRuntimeDir().
The homedir.GetRuntimeDir() function returns a value also when running
as root so it can be used inside a nested Podman.

Currently --tmpdir changes the location of the pause.pid file. this
causes issues because the c code in pkg/rootless does not know about
that. I tried to fix this[1] by fixing the c code to not use the
shortcut. While this fix worked it will result in many pause processes
leaking in the integrration tests.
Commit ab88632 added this behavior but following the disccusion it was
never the intention that we end up having more than one pause process.
The issues that was trying to fix was caused by somthing else AFAICT,
the main problem seems to be that the pause.pid file parent directory
may not be created when we try to create the pid file so it failed with
ENOENT. This patch fixes it by creating this directory always and revert
the change to no longer depend on the tmpdir value.
With this commit we now always use XDG_RUNTIME_DIR/libpod/tmp/pause.pid
for all podman processes. This allows the c shortcut to work reliably
and should therefore improve perfomance over my other approach.
A system test is added to ensure we see the right behavior and that
podman system migrate actually stops the pause process. Thanks to Ed
Santiago for the improved test to make it work for both `catatonit` and
`podman pause`.
This should fix the issues with namespace missmatches that we can see in
CI as flakes.

Previously, we always computed pause path from the Rootless
runtime directory. Problem: this does not match the behavior of
Libpod when the directory changes. Libpod will continue to use
the previous directory, cached in the database; Pause pidfiles
will swap to the new path. This is problematic when the directory
needs to exist to write the pidfile, and Libpod is what creates
the directory.
There are two potential solutions - allow the pause pidfile to
move and just make the directory when we want to write it, or use
the cached Libpod paths for a guaranteed location. This patch
does the second, because it seems safer - we will never miss a
previously-existing pidfile because the location is now
consistent.

We need to block systemd from cleaning up this directory

In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like
fails, the error message already contains the file name and the
operation that fails, so there is no need to wrap the error with
something like "open %s failed".
While at it
- replace a few places with os.Open, ioutil.ReadAll with
ioutil.ReadFile.
- replace errors.Wrapf with errors.Wrap for cases where there
are no %-style arguments.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

when we use namespaces, we set the run directory to 0711 to allow
other users to access it.
without this relaxation, the /run/user/$UID directory would be
skipped.

Currently, we return a runtime directory of the form
`/run/user/<uid>`, even when running as root. Depending on configuration,
that directory may be deleted when the user logs out, which is quite
awkward when the container is started as a systemd service and then
someone logs in and out as root.
This patch fixes the problem by returning an empty runtime directory if the
container is being started by root. The runtime should automatically use
the default runtime directory (`/run/crun` when crun is used), which should
be accessible to root.
Tested in Fedora 31 by running containers under both root and a regular
user. State for root containers is stored in `/run/crun`, while state for
rootless containers is in `/run/user/<uid>/crun`.

Do not require 0755 permissons for the ~/.config directory but require
at least 0700 which should be sufficient. The current implementation
internally creates this directory with 0755 if it does not exist, but if the
directory already exists with different perissions the current code returns
an empty string.

use a pause process to keep the user and mount namespace alive.
The pause process is created immediately on reload, and all successive
Podman processes will refer to it for joining the user&mount
namespace.
This solves all the race conditions we had on joining the correct
namespaces using the conmon processes.
As a fallback if the join fails for any reason (e.g. the pause process
was killed), then we try to join the running containers as we were
doing before.
