Summary:

SELinux prevented mount from mounting on the file or directory "/mnt/live" (type
"iso9660_t").

Detailed Description:

SELinux prevented mount from mounting a filesystem on the file or directory
"/mnt/live" of type "iso9660_t". By default SELinux limits the mounting of
filesystems to only some files or directories (those with types that have the
mountpoint attribute). The type "iso9660_t" does not have this attribute. You
can change the label of the file or directory.

Allowing Access:

Changing the file_context to mnt_t will allow mount to mount the file system:
"chcon -t mnt_t '/mnt/live'." You must also change the default file context
files on the system in order to preserve them even on a full relabel. "semanage
fcontext -a -t mnt_t '/mnt/live'"

Fix Command:

chcon -t mnt_t '/mnt/live'
