I've never heard of chrootbeg, google's never heard of chrootbeg, and my system doesn't have it. I think you took someone's instructions a little too literally. Those are labels for you, telling you 'run all this stuff in a chroot'.

Further, chroot doesn't work that way, neither does sudo nor any other shell. No interpreter will stop in the middle, start executing a totally different language, then return to where you were without being asked -- if you want to put commands into something else, you have to tell the shell to put them there.

chroot works like:

Code:
chroot /path/to/newroot /bin/sh

...and from there on out, reads interactively. Though simple commands will work noninteractively. (apt-get and the like are prone to prompt you for y/n, so your mileage may vary.) You could put the inside-chroot stuff into a script file and run it:

Code:
chroot /path/to/newroot /bin/sh < /path/to/scriptfile

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
