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.

uuidgen - command-line utility to create a new UUID value
uuidgen [-r|-t]
The uuidgen program creates (and prints) a new universally unique identifier (UUID) using the libuuid(3) library. The new UUID can reason- ably be considered unique among all UUIDs created on the local system, and among UUIDs created on other systems in the past and in the future. There are two types of UUID's which uuidgen can generate: time-based UUID's and random-based UUID's. By default uuidgen will generate a random-based UUID if a high-quality random number generator is present. Otherwise, it will chose a time-based UUID. It is possible to force the generation of one of these two UUID types by using the -r or -t options.
-r Generate a random-based UUID. This method creates a UUID consisting mostly of random bits. It requires that the operating system have a high quality random number generator, such as /dev/random. -t Generate a time-based UUID. This method creates a UUID based on the system clock plus the system's ethernet hardware address, if present.
uuidgen was written by Andreas Dilger for libuuid.
The uuidgen command is part of the util-linux-ng package and is available from
