Remove `installing from SunOS' and `installing from Solaris' instructions.

They are much more troublesome than using the miniroot, and if you're actually still running a SunOS setup in 2015, then you're me, and you don't need to be told this information anyway. Do not suggest disks might be shared between OpenBSD and SunOS or Solaris anymore. This is just asking for trouble.

-Installing from SunOS:

-You need a SunOS machine to install OpenBSD. You also need at

-least the following pieces:

- - the *.tgz files you want to install (as a minimum, base{:--:}OSrev.tgz and

- etc{:--:}OSrev.tgz)

- - gunzip (GNU gzip) SunOS binary

- - gtar (GNU tar) SunOS binary

- - a "/boot" file from a SunOS machine that matches your machine type

- (e.g. sun4m or sun4c)

- - an OpenBSD kernel, most likely "/bsd"

-All these pieces, except "/boot" and the GNU utilities, are supplied in

-the OpenBSD/MACHINE distribution.

-You need to format and partition the disk using SunOS (since

-OpenBSD/MACHINE uses SunOS disk labels.) Give yourself adequate

-partition sizes. Here is an example layout:

- partition size offset will be..

- sd0a 80000 0 /

- sd0b 256000 80000 swap

- sd0c 4165271 0 `whole disk'

- sd0d 100000 436000 /var

- sd0f 100000 336000 /tmp

- sd0g 3229271 936000 /usr

- sd0h 400000 536000 /var/tmp

-Use SunOS to newfs the partitions which will have filesystems on them.

-(OpenBSD's filesystem format is almost identical to SunOS.)

- sunos# newfs /dev/rsd0a

- [... lots of output]

-Repeat for any other partition (in this example, /dev/rsd0d, /dev/rsd0f,

-/dev/rsd0g, /dev/rsd0h).

-NOTE: If you are able to, there is a performance benefit from

-newfs'ing using OpenBSD. If you newfs using the OpenBSD newfs command,

-be sure to use the -O flag for your / partition, so that newfs will

-use the 4.3BSD filesystem format, rather than the new 4.4BSD filesystem

-format. If you forget, you will not be able to boot -- the SunOS boot

-blocks do not understand the extended 4.4BSD filesystem format.

-Mount those partitions in a tree formation, under /mnt; ie:

- sunos# df

- Filesystem kbytes used avail capacity Mounted on

- [...]

- /dev/sd0a 38427 0 38427 0% /mnt

- /dev/sd0d 48249 0 48249 0% /mnt/var

-Place a standard SunOS "boot" program in /mnt (your new root

-partition), and use the SunOS command "installboot" to make it work.

-The installboot man page says to do something like this:

- sunos# cp /usr/mdec/sdboot /mnt/boot

- sunos# sync; sync

- sunos# /usr/mdec/installboot -vlt /mnt/boot /usr/mdec/bootsd /dev/rsd2a

- sunos{:-#-:} gunzip < base{:--:}OSrev.tgz | (cd /mnt; gtar xvpf -)

- [...] for each set

-And finally copy the OpenBSD kernel onto your disk.

- sunos# cp bsd /mnt/bsd

-The GNU gunzip and gtar programs are not distributed as part of SunOS,

-but may be present in your /usr/local/bin. If not, you will need to

-obtain them from a GNU archive and install before proceeding. The

-OpenBSD tar files are in the "new format" that includes directory

-information, and the standard SunOS tar will not extract from them

-successfully.

-After the files have been extracted, set up /mnt/etc/fstab to match

-your actual disk layout. (Minus the "/mnt" component of each path, of

-course :-)

-- a boot block file from a Solaris machine that matches your machine type,

- for ufs filesystem, such as /usr/platform/`uname -i`/lib/fs/ufs/bootblk

-- an OpenBSD kernel, most likely "/bsd"

-All these pieces, except the boot block and the GNU utilities, are supplied

-in the OpenBSD/MACHINE distribution.

-You need to format and partition the disk using Solaris (since

-OpenBSD/MACHINE uses Sun compatible disk labels). Give yourself adequate

-partition sizes. Here is an example layout:
