Subuser turns a docker container into a normal program. This program, however,
runs with restricted privileges. It can only access the directory from which it was
called, not the user's entire home directory. Each subuser is assigned a
specific set of permissions.
Notes:
Ensure that all dependencies are installed before running this slackbuild.
The package 'google-go-lang' must be build and installed before 'runc' package.
If 'runc' fails to build then reboot and try again.
