Subject: [PATCH 01/38] [sosreport] add --sysroot option
Add a --sysroot=SYSROOT option to specify that the root file system to
be inspected is mounted at SYSROOT.
This allows basic support for container environments where sos is
running in a container and inspecting the containing host and its
environment ('superspection').
For this to work currently the following conditions must be met:
- sos is sufficiently privileged to read and search relevant file
system paths within SYSROOT
- sos must share the PID and network namespace of the target host
- binaries called by sos must be present and executable in the
SYSROOT inherited by sos. If PATH includes paths inside SYSROOT
appropriate values must be set for LD_LIBRARY_PATH to allow
shared executables to be linked.

Subject: [PATCH 02/38] [plugins] propagate sysroot to Plugin via commons
Although plugins should generally be unaware that they are being
run with an alternate sysroot the generic plugin IO code must
peform the appropriate path prefixing when sysroot is not '/'.
Propagate sysroot to plugin classes via the commons dictionary.

Subject: [PATCH 03/38] [plugins] prefix target paths with self.sysroot
Prefix copyspecs with self.sysroot when using an alternate root
path. Prefixes are applied before expanding copyspecs and the
prefixed paths are stored as the 'srcpath' attribute in the
archive. Destination paths in the report archive do not include
the prefix.

Subject: [PATCH 06/38] [sosreport] add --chroot option
Add a --chroot option to sosreport to control command chrooting.
The option takes one of three values:
* auto - Allow callers of the API to control chroot behaviour
* always - Always chroot external commands to --sysroot
* never - Never chroot external commands
This is a fairly low-level option and may not be exposed to the
user in a final release; for now it will allow tests in container
environments to control the chrooting behaviour used for a run.

Expose sos_get_command_output()'s chroot support to plugins via
add_cmd_output(), get_command_output(), call_ext_prog() and
related Plugin methods.
'chroot' is a boolean indicating whether the command should run
in the chroot (True) or in the host namespace (False).
Has no effect when Plugin.use_sysroot() is False.

Subject: [PATCH 11/38] [plugin] add tmp_in_sysroot() method
Add a method that plugins can test to determine whether the
archive's temporary directory is inside sysroot. This is always
true when sysroot is '/'. When sysroot is a subdirectory of root
the temporary directory may be inaccessible from the chroot
namespace. Plugins can test this method to determine where to
write output.

Subject: [PATCH 20/38] [plugin] handle ELOOP in _copy_dir()
A problem with systemd's management of the binfmt_misc automount
point in Atomic environments causes attempts to access this path to
fail with ELOOP:
>>> import os
>>> os.listdir("/host/proc/sys/fs/binfmt_misc/")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 2] No such file or directory: '/host/proc/sys/fs/binfmt_misc/'
For reasons that are not yet clear this causes the entire sos
process to immediately terminate.
For now avoid the problem by enclosing the problem os.listdir in
a try/except block that explicitly handles the one errno value
implicated here.

Subject: [PATCH 32/38] [policies/redhat] automatically set tmp_dir in
containers
Now that policies have the infrastructure to detect that they
are running in a container and to use the HOST environment
variable if present enable automatic setting of self._tmp_dir in
appriate container environments.
This causes reports to be automatically written to $HOST/var/tmp
when $HOST is set while still allowing users to override the tmp
path manually by specificying --tmp-dir=PATH.
