:SELinux is preventing /usr/sbin/mount.ecryptfs_private from 'write' accesses on the key .
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that mount.ecryptfs_private should be allowed write access on the  key by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep umount.ecryptfs /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
