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.

NAME
installgrub - install GRUB in a disk partition or a floppy
SYNOPSIS
/sbin/installgrub [-fm] stage1 stage2 raw-device
DESCRIPTION
The installgrub command is an x86-only program. GRUB stands for GRand Unified Bootloader. installgrub installs GRUB stage 1 and stage 2 files on the boot area of a disk partition. If you specify the -m option, installgrub installs the stage 1 file on the master boot sector of the disk.
OPTIONS
The installgrub command accepts the following options: -f Suppresses interaction when overwriting the master boot sector. -m Installs GRUB stage1 on the master boot sector interactively. You must use this option if Solaris is installed on an extended parti- tion.
OPERANDS
The installgrub command accepts the following operands: stage1 The name of the GRUB stage 1 file. stage2 The name of the GRUB stage 2 file. raw-device The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable. For disk devices, specify the slice where the GRUB menu file is located. (For Solaris it is the root slice.) For a floppy disk, it is /dev/rdiskette.
EXAMPLES
Example 1 Installing GRUB on a Hard Disk Slice The following command installs GRUB on a system where the root slice is c0d0s0: example# /sbin/installgrub /boot/grub/stage1 \ /boot/grub/stage2 /dev/rdsk/c0d0s0 Example 2 Installing GRUB on a Floppy The following command installs GRUB on a formatted floppy: example# mount -F pcfs /dev/diskette /mnt # mkdir -p /mnt/boot/grub # cp /boot/grub/* /mnt/boot/grub # umount /mnt # cd /boot/grub # /sbin/installgrub stage1 stage2 /dev/rdiskette

WARNINGS
Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always boot the GRUB in the Solaris partition regardless of which fdisk partition is active. SunOS 5.11 31 Oct 2008 installgrub(1M)
