Iso - remaster script trying to start chroot run commands then exit but host system gets messed up
The script works and creates a modified iso fine until I added the chrootbeg and chrootend functions and executed them. I'm sorry if I did something wrong this is my first post. I uploaded entire bash script for reference or in case you want to run it to debug it is called isoremast.txt.

Please let me know if you need more information and I'll be happy to provide it. Thank you.

Summary of script

USAGE: isoremast (no options) - Will DL iso and uncompress image
isoramst m - Will modify the iso files by adding, deleting, etc
possibly by chrooting into the system
isoremast c - Will recreate the iso file with your modifications

Script was written to be run 'isoremast m' mult times in a row
and change the script to easily add or delete files without having
to recreate the iso each time - useful for rapid testing
Also several other proj do something similar but use a myraid of scripts
and programs to do so. Want all functionality need in 1 script this
is my goal along with simplicity so my 8 year old can run it
without having to type a myriad of commands into the terminal.

Setup - Running golang webserver on Win 7 host running Debian 10 as a VM guest running the script

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
