I'm trying to use the "mknod" call in C to create a clone of /dev/null. I am stumped as to the final parameter I should provide to "mknod()". I am supposed to give it a type dev_t, which specifies a major & minor number. I want to specify major 3, minor 1, but how can I do this?
dev_t seems to... (2 Replies)

Trying to clone an old V240 (sun4u) onto a new T2000 (sun4v).
Managed to create a flar on the V240. Worked out that you need to add the sun4v architecture to the flar (-U "content_architecture=sun4u,sun4v" in the flarcreate).
Anyway, copied that to spare 2nd disk on my target T2000. Booted... (2 Replies)

grub - GRand Unified Bootloader software on Solaris
The current release of the Solaris operating system is shipped with the GRUB (GRand Unified Bootloader) 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 transfer-
ring 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 example, 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, by means of
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. [Ed. note: Sun 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 position 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 platforms. The GRUB software that is shipped with Solaris adds two utilities not present in
the open-source distribution:
bootadm(1M)
Enables you to manage the boot archive and make changes to the GRUB menu.
installgrub(1M)
Loads the boot program from disk.
Both of these utilities are described in Solaris man pages.
Beyond these two Solaris-specific utilities, the GRUB software is described in the GRUB manual, a PDF version of which is available from
the Sun web site. Available in the same location is the grub(8) open-source man page. This man page describes the GRUB shell.
