Description of problem:
SELinux is preventing loadkeys from 'open' accesses on the chr_file /dev/tty1.

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

If you want to allow daemons to use tty
Then you must tell SELinux about this by enabling the 'daemons_use_tty' boolean.

setsebool -P daemons_use_tty 1

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

If you believe that loadkeys should be allowed open access on the tty1 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'loadkeys' --raw | audit2allow -M my-loadkeys
# semodule -X 300 -i my-loadkeys.pp
