I was reading an article on how it is very important to setup a chroot jail to run bind. I can follow what the article says but one thing I am unclear about is now on system boot the BIND process in the chroot jail will start since it the owner will no longer be root but some other user.

mkcd
mkcd(1M) System Administration Commands mkcd(1M)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
