As you know, I’ve been studying for the RHCE exam. One of the things that I was unsure about with SELinux was how to find all the available contexts. It’s easy to find booleans with the ‘getsebool’ command, but what about a context?

[root@sgnhv ~]# ls -Z /var/lib/ | grep virt
drwxr-xr-x. root    root    system_u:object_r:virt_var_lib_t:s0 libvirt

There are TONS of contexts. Today, I found my answer. It’s the ‘seinfo’ command.
