You can customize an SELinux policy by enabling or disabling the members of a set of Boolean values. Any changes that you make take effect immediately and do not require a reboot.

To display the Boolean values and their descriptions, use the following command:

semanage boolean -l

SELinux boolean                State  Default Description

ftp_home_dir                   (off  ,  off)  
Determine whether ftpd can read and write files in user home directories.
smartmon_3ware                 (off  ,  off)  
Determine whether smartmon can support devices on 3ware controllers.
mpd_enable_homedirs            (off  ,  off)  
Determine whether mpd can traverse user home directories.
...

You can use the getsebool and setsebool commands to display and set the value of a specific Boolean.

getsebool boolean
sudo setsebool boolean on|off

The following example shows how you to display and set the value of the ftp_home_dir Boolean:

getsebool ftp_home_dir
ftp_home_dir --> off
sudo setsebool ftp_home_dir on
getsebool ftp_home_dir
ftp_home_dir --> on

To switch the value of a Boolean, use the togglesebool command, as shown in the following example:

sudo togglesebool ftp_home_dir
ftp_home_dir: inactive

sudo setsebool -P ftp_home_dir on
getsebool ftp_home_dir
ftp_home_dir --> on
