NAME
grub - GRand Unified Bootloader 2 software on Oracle Solaris
DESCRIPTION
The current release of the Oracle Solaris operating system is shipped
with the GRUB (GRand Unified Bootloader) 2 software. GRUB is developed
and supported by the Free Software Foundation.
The overview for the GRUB Manual, accessible at www.gnu.org, describes
GRUB:
Briefly, a boot loader is the first software program that runs when a
computer starts. It is responsible for loading and transferring control
to an operating system kernel software (such as Linux or GNU Mach). The
kernel, in turn, initializes the rest of the operating system (for ex‐
ample, a GNU [Ed. note: or Solaris] system).
GNU GRUB is a very powerful boot loader that can load a wide variety of
free as well as proprietary operating systems with chain-loading. GRUB
is designed to address the complexity of booting a personal computer;
both the program and this manual are tightly bound to that computer
platform, although porting to other platforms may be addressed in the
future. Note: Oracle has ported GRUB to the Solaris operating system.
One of the important features in GRUB is flexibility; GRUB understands
filesystems and kernel executable formats, so you can load an arbitrary
operating system the way you like, without recording the physical posi‐
tion of your kernel on the disk. Thus you can load the kernel just by
specifying its file name and the drive and partition where the kernel
resides.
Among Solaris machines, GRUB is supported on x86 platforms. The GRUB
software that is shipped with Solaris adds one utility not present in
the open-source distribution:
bootadm(8) Enables you to manage the boot archive and make changes to
the GRUB menu.
Beyond this Solaris-specific utility, the GRUB software is described in
the GRUB manual, a PDF version of which is available from the Oracle
website.
Most administrators will not need to manually execute the GRUB utili‐
ties (which can be found in /usr/lib/grub2/bios and
/usr/lib/grub2/uefi64 for systems with BIOS firmware and 64-bit UEFI
firmware, respectively), as bootadm(8) provides an interface to modify‐
ing the GRUB menu.
Administrators should not manually edit the GRUB configuration file,
grub.cfg, which can be found in the /boot/grub subdirectory of the top-
level ZFS dataset for the system's root pool (that is,
/rpool/boot/grub). This file is automatically regenerated when an ad‐
ministrator changes the boot configuration with bootadm(8). Advanced
administrators who want to directly create GRUB menu entries must edit
the supplemental GRUB configuration file named custom.cfg, which is
stored in the same directory as the grub.cfg file. Note that on a
freshly-installed system, this file will not be present, so the admin‐
istrator will need to create it.

NOTES
Previous versions of Solaris have documented the use of the installgrub
command for installing the GRUB boot loader. This command is deprecated
and is present ONLY for convenience, disaster recovery, and downgrading
back to a Solaris boot environment in which GRUB Legacy is the system
boot loader. Please consult the Booting and Shutting Down Oracle So‐
laris 11.4 Systems documentation for further details.
