audit.log shows that journald needs to read the kernel read buffer:
avc: denied { syslog_read } for pid=147 comm="systemd-journal" scontext=system_u:system_r:syslogd_t tcontext=system_u:system_r:kernel_t tclass=system permissive=1
Moreover journald uses RW access to /dev/kmsg, according to its code:
http://cgit.freedesktop.org/systemd/systemd/tree/src/journal/journald-kmsg.c?id=v215#n394
On ArchLinux the directory name of Network Manager in /usr/lib is
written in lowercase but not the files in /usr/bin, /var/lib, etc.
While at it, remove a useless backslash before a minus character.
The kernel_delete_unlabeled_chr_files interface is called by the
(deprecated) files_delete_isid_type_chr_files interface in
kernel/files.if.

The kernel_delete_unlabeled_symlinks interface is called by the
files_delete_isid_type_symlinks interface (in kernel/files.if). This
interface is deprecated (and calls kernel_delete_unlabeled_symlinks).

The dropbox application has a feature called "LAN Sync" which works on
TCP & UDP port 17500. Marking this port as dropbox_port_t (instead of
the currently default unreserved_port_t) allows for more fine-grained
access control to this resource.

Currently, the /usr/share/cvs/contrib/rcs2log is only labeled as bin_t
for redhat distributions. Moving this to the general one as it is also
in use on other distributions

Since commit 2d0c9cec mls_file_read_up and mls_file_write_down
interfaces are deprecated even though they are still present.
Replace mls_file_read_up with mls_file_read_all_levels and
mls_file_write_down with mls_file_write_all_levels.
On ArchLinux, glibc package installs /usr/bin/getconf as a hard link to a file
in /usr/lib/getconf/. For example on a x86_64 machine:
$ ls -i -l /usr/bin/getconf /usr/lib/getconf/XBS5_LP64_OFF64
5900355 -rwxr-xr-x. 4 root root 22880 Feb 28 04:53 /usr/bin/getconf
5900355 -rwxr-xr-x. 4 root root 22880 Feb 28 04:53 /usr/lib/getconf/XBS5_LP64_OFF64
Such configuration produces an instability when labeling the files with
"restorecon -Rv /":
restorecon reset /usr/bin/getconf context unconfined_u:object_r:lib_t:s0->unconfined_u:object_r:bin_t:s0
restorecon reset /usr/lib/getconf/XBS5_LP64_OFF64 context unconfined_u:object_r:bin_t:s0->unconfined_u:object_r:lib_t:s0
As /usr/lib/getconf directory only contains executable programs, this issue is
fixed by labeling this directory and its content "bin_t".
/sys/fs/cgroup is a tmpfs which contains cgroup mounts and symlinks such as
cpu and cpuacct. Running restorecon makes this warning happen:
restorecon: Warning no default label for /sys/fs/cgroup/cpu
Declare a file context for every symlink in the cgroup tmpfs montpoint to
no longer have such warning.
Even if there is not FHS provision for this, systemd is using
/dev/hugepages to mount the hugetlbfs fs by default.
The needed file contexts are already present
