I've just briefly tried setting up puppet and here are some policy changes.
The label of the /var/cache/puppet directory doesn't have policy because I
didn't get to the stage of it being used (contributions welcome).
The corecmd_bin_entry_type() lines are the most important thing as puppet
is started by a common command for both server and agent, so we need stuff
Why isn't this executable labeled with puppet_exec_t? Am I missing something?
like the below in systemd service files.
[Service]
SELinuxContext=system_u:system_r:puppet_t:s0
[Service]
SELinuxContext=system_u:system_r:puppetmaster_t:s0
I have some other possible changes for Puppet, if someone who knows it well
would like to have a discussion about that.
