When reading or managing noxattr fs files or symbolic links, also
let the user list noxattr fs directories.
This patch should be applied after the following one:

Let unprivileged users list filesystems mounted on mount points such
as /mnt (cdrom, FAT, NTFS and so on).
This makes a great difference to the usability and effectiveness of
graphical filesystem browsers such as Gnome Nautilus and currently
comes at no security penalty because mounted filesystems can be
listed with programs such as the "df" program from GNU coreutils or
by simply reading /proc/mounts.

Let unprivileged and administrative users read symbolic links on
filesystems that do not support extended attributes (xattr) such
as cdroms, FAT, NTFS and so on.

As we have had no response from Busybox users in the last 3 months and also no
response to the thread Luis started in 2013 I think it's safe to assume that
they don't need this.
I've attached a new patch which renames to kmod_t as you suggested. Please
consider it for inclusion.

Description: Change modutils policy to match the use of a single binary
Author: Russell Coker <russell@coker.com.au>
Last-Update: 2014-06-25
commit a7334eb0de98af11ec38b6263536fa01bc2a606c
libsemanage: validate and compile file contexts before installing
validates the fcontexts when they are still in /var/lib/selinux. Without
setfiles_t having access to read the files, validation fails and the
policy cannot be updated.
Introduce a new file context for user certificates (user_cert_t)
located in home directories.
Introduce new auxiliary interfaces to read and manage such files
files and directories.
Thanks to Christopher PeBenito for the useful suggestions that
led to this improved version of the patch.
Compared to the previous version, this patch adds the ability to
search the user home directories in the new interfaces.
