5.3. Booleans

SELinux is based on the least level of access required for a service to run. Services can be run in a variety of ways; therefore, you need to specify how you run your services. Use the following Booleans to set up SELinux:
allow_ftpd_use_nfs
When enabled, this Boolean allows the ftpd daemon to access NFS volumes.
cobbler_use_nfs
When enabled, this Boolean allows the cobblerd daemon to access NFS volumes.
git_system_use_nfs
When enabled, this Boolean allows the Git system daemon to read system shared repositories on NFS volumes.
httpd_use_nfs
When enabled, this Boolean allows the httpd daemon to access files stored on NFS volumes.
qemu_use_nfs
When enabled, this Boolean allows Qemu to use NFS volumes.
rsync_use_nfs
When enabled, this Boolean allows rsync servers to share NFS volumes.
samba_share_nfs
When enabled, this Boolean allows the smbd daemon to share NFS volumes. When disabled, this Boolean prevents smbd from having full access to NFS shares via Samba.
sanlock_use_nfs
When enabled, this Boolean allows the sanlock daemon to manage NFS volumes.
sge_use_nfs
When enabled, this Boolean allows the sge scheduler to access NFS volumes.
use_nfs_home_dirs
When enabled, this Boolean adds support for NFS home directories.
virt_use_nfs
When enabled, this Boolean allows confident virtual guests to manage files on NFS volumes.
xen_use_nfs
When enabled, this Boolean allows Xen to manage files on NFS volumes.
git_cgi_use_nfs
When enabled, this Boolean allows the Git Common Gateway Interface (CGI) to access NFS volumes.
tftp_use_nfs
When enabled, this Boolean allows The Trivial File Transfer Protocol (TFTP) to read from NFS volumes for public file transfer services.

Note

Due to the continuous development of the SELinux policy, the list above might not contain all Booleans related to the service at all times. To list them, run the following command as root:
~]# semanage boolean -l | grep service_name
