[PATCH 0/2] kernel-shark: Let polkit decide the environment and path of kshark-record

[Steven Rostedt]

As the policy defined in the polkit actions for KernelShark Record define
both the environment ($DISPLAY and $XAUTHORITY) as well as the path
to the executible, no need to add hacks to the kshark-su-record that
is used. Just revert the code that did so.

      kernel-shark: Revert adding environment variables to kshark-su-record
      kernel-shark: Revert adding relative path to policy installation

[PATCH 1/2] kernel-shark: Revert adding environment variables to kshark-su-record

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

This reverts:

  8eb0d753e ("kernel-shark: Execute kshark-record from same dir as kshark-su-record")
  b084eb5aa ("kernel-shark: Set the DISPLAY environment for pkexec kshark-record")

As the policykit (when installed correctly), should handle both the path to
the executable, as well as the DISPLAY and XAUTHORITY environment variables.

[PATCH 2/2] kernel-shark: Revert adding relative path to policy installation

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

This reverts the change in a45ab5a44 ("kernel-shark: Remove hard-coded
install paths") that removed the full path of installing
org.freedesktop.kshark-record.policy to a relative path. This means if we
installed in /usr/local/bin the policy still needs to go into
/usr/share/polkit-1/actions/

This does not affect DESTDIR, as installing still goes in the relative path
from DESTDIR for package maintainers.
