I believe PWB/UNIX was based on Version 7 (not version 1-4). If it wasn't based on V7, it certainly had significant input from V7.

SunOS 4 was not a dead end (as shown n the diagram). Solaris 2.0 (not shown in the diagram) was the result of a grand merge of SunOS 4 and UNIX System V Release 4. SunOS 4.1 (also not shown in the diagram) also contained significant input from UNIX SVR4 and was a major step towards Solaris 2.0 (containing SunOS 5.0), but /bin and /usr/bin utilities in SunOS 4.1 were still BSD based (with some SVR4 extensions) while /bin and /usr/bin utilities in Solaris 2.0/SunOS 5.0 were SVR4 based with BSD extensions.

Some BSD 4.4 features were also merged into SunOS 4.1 and Solaris 2.x, but that is not shown in the diagram.

NAME
mkcd - create bootable Solaris ISO image SYNOPSIS
/usr/bin/mkcd -v [-l label] media-root iso DESCRIPTION
The mkcd utility takes media-root (the root of an on-disk Solaris install media) as input and creates a bootable Solaris ISO image in the file iso, using mkisofs(8). The file can then be burned onto a CD/DVD with utilities such as cdrw(1) or cdrecord(1). (Neither mkisofs(8) nor cdrecord(1) are SunOS man pages.) Caution - The directory tree media-root must contain the file boot/grub/stage2_eltorito, which will be written to the media boot sectors. This file will be modified with some boot information, thus it must be writable. If necessary, first save a copy prior to running this utility. OPTIONS
The following options are supported: -l label Sets label as the label/volume name of the ISO image. -v Verbose. Multiple -v options increase verbosity. OPERANDS
The following operands are supported: media-root Top-level directory of an on-disk Solaris install media. iso Name of the output file which will contain the resulting ISO image. EXAMPLES
Example 1 Creating an ISO Image and Burning a CD/DVD The following commands create an ISO image from the content of s10u1 and burn the image to a CD/DVD. # /usr/bin/mkcd s10u1 s10u1.iso # /usr/bin/cdrw -i s10u1.iso ATTRIBUTES
