Since commit 0fd9dc55, logging.te contains:
term_write_all_user_ttys(syslogd_t)
As "write" is a superset of "append", this rule is no longer needed:
term_append_unallocated_ttys(syslogd_t)
While at it, add a comment which explains why
term_dontaudit_setattr_unallocated_ttys is needed.
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.
Currently, all postgresql commands in are labeled as postgresql_exec_t.
This means they can only be executed by db admins. However, the "normal"
commands, such as createdb or psql, should also be executable by users.
(The users in question still need to be granted postgresql_role(), so
this is no security problem.)
If the (sadly nearly undocumented) Linux kernel feature which allows
specific user groups to send ICMP echos without CAP_NET_RAW
(configurable with the sysctl net.ipv4.ping_group_range, available since
3.0) is used, ping needs the getattr permission of the rawip_socket
class in order to work.

interface is deprecated (and calls kernel_delete_unlabeled_symlinks).

These are seldomly-used tools from the util-linux package.
Please check if they are located in /sbin instead of /usr/sbin on other
distributions.
