Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

posix1e -- introduction to the POSIX.1e security API
Standard C Library (libc, -lc)
#include <sys/types.h> #include <sys/acl.h> #include <sys/mac.h>
POSIX.1e describes five security extensions to the POSIX.1 API: Access Control Lists (ACLs), Auditing, Capabilities, Mandatory Access Con- trol, and Information Flow Labels. While IEEE POSIX.1e D17 specification has not been standardized, several of its interfaces are widely used. FreeBSD implements POSIX.1e interface for access control lists, described in acl(3), and supports ACLs on the ffs(7) file system; ACLs must be administratively enabled using tunefs(8). FreeBSD implements a POSIX.1e-like mandatory access control interface, described in mac(3), although with a number of extensions and impor- tant semantic differences. FreeBSD does not implement the POSIX.1e audit, privilege (capability), or information flow label APIs. However, FreeBSD does implement the libbsm audit API. It also provides capsicum(4), a lightweight OS capability and sandbox framework implementing a hybrid capability system model.
POSIX.1e assigns security attributes to all objects, extending the security functionality described in POSIX.1. These additional attributes store fine-grained discretionary access control information and mandatory access control labels; for files, they are stored in extended attributes, described in extattr(3). POSIX.2c describes a set of userland utilities for manipulating these attributes, including getfacl(1) and setfacl(1) for access control lists, and getfmac(8) and setfmac(8) for mandatory access control labels.
getfacl(1), setfacl(1), extattr(2), acl(3), extattr(3), libbsm(3), libcapsicum(3), mac(3), capsicum(4), ffs(7), getfmac(8), setfmac(8), tunefs(8), acl(9), extattr(9), mac(9)
POSIX.1e is described in IEEE POSIX.1e draft 17.
POSIX.1e support was introduced in FreeBSD 4.0; most features were available as of FreeBSD 5.0.
