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

NAME

       Encode::Byte - Single Byte Encodings

SYNOPSIS

	   use Encode qw/encode decode/;
