Description Yajo 2013-03-26 21:22:35 UTC
Description of problem:
Switch to tty1 (GNOME) after some work in tty2 (terminal).
SELinux is preventing /usr/sbin/mount.ecryptfs_private from 'write' accesses on the key .

*****  Plugin catchall (100. confidence) suggests  ***************************

If cree que de manera predeterminada, mount.ecryptfs_private debería permitir acceso write sobre   key.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep umount.ecryptfs /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
