There's not really any point just documenting that people should label the tmp directory, when we can just label it. So change the ./run script so it calls chcon. However it's not a failure if chcon doesn't work. If SELinux is not installed or is disabled, then labelling will fail.

# With this script you can run all the virt tools without needing to

# install them first. You just have to do for example:
|

#
|
|
# ./run ./inspector/virt-inspector [args ...]
|
|
#
|

# This works for any C program, virt tools, and most non-C bindings

# and programs in the libguestfs distribution. Also you can make a

# symbolic [not hard] link to this 'run' script from anywhere
|
|
# (eg. $HOME/bin/run) if you wish.
|

#
|

|

# TESTS_ENVIRONMENT = ... $(top_builddir)/run --test [$(VG)]
|

# (Use the optional $(VG) when the tests must also be run under
|
|
# valgrind).
