Description of problem:
SELinux is preventing loadkeys from 'open' accesses on the chr_file /dev/tty2.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow all daemons the ability to read/write terminals
Then è necessario informare SELinux abilitando il booleano 'daemons_use_tty' .
Per maggiori informazioni consultare le pagina man di 'loadkeys_selinux'.
Do
setsebool -P daemons_use_tty 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that loadkeys should be allowed open access on the tty2 chr_file by default.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
allow this access for now by executing:
# ausearch -c 'loadkeys' --raw | audit2allow -M my-loadkeys
# semodule -X 300 -i my-loadkeys.pp
