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.

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. Can... (1 Reply)

dtc_write_xenhvm_conf
dtc_write_xenhvm_conf(8) System Manager's Manual dtc_write_xenhvm_conf(8)NAME
dtc_write_xenhvm_conf - rewrites the xen startup script with selected params
SYNOPSIS
dtc_write_xenhvm_conf VPS_NUMBER MEMORY_SIZE ALL_IP_ADDRESSES VNC_CONSOLE_PASSWORD HOW_TO_BOOT
DESCRIPTION
dtc_write_xenhvm_conf This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server.
This script generate a Xen startup file with the parameters given to the script.
PARAMETERS
Note that ALL parameters are mendatory.
VPS_NUMBER has to be a number between 01 and 29
MEMORY_SIZE is the amount of memory in mega bytes that you want to have setup in the Xen startup file for this VPS
ALL_IP_ADDRESSES is a list of IPs that you want to be set in the VM's startup file and in the VM's configuration. Note that the IPs have to
be separated by spaces, and thus you might want to use single quotes like this: '1.2.3.4 1.2.3.5'. Note that only the first IP will be set
in the VM's configuration, but the list will be set in the Xen startup file so you can use the anti-spoofing facilities of Xen if you need
it (with untrusted users / unknown customers for example).
VNC_CONSOLE_PASSWORD This is the VNC console password that you want to have set-up in the Xen domU configuration file, so that you can con-
nect using VNC to the the setup. Note that special value no_vnc can be used to declare that you do not want the VNC console to be used at
all.
HOW_TO_BOOT This controls what the VPS will use to boot. A special value of hdd can be used to tell dtc_write_xenhvm_conf that you want to
boot on the hard drive of the domU. Any other parameters will be used as a .iso file located in /var/lib/dtc-xen/ttyssh_home/xenXX where
xenXX equals to the VPS number set in the VPS_NUMBER parameter (see above).
Note that whatever is set in this parameter, dtc_write_xenhvm_conf will add as many cdrom devices as it finds .iso files in the
/var/lib/dtc-xen/ttyssh_home/xenXX folder.
EXAMPLE
The following command:
dtc_write_xenhvm_conf 14 512 '1.2.3.4 1.2.3.5' mYvNcPaSs boot.iso
will produce this config file in /etc/xen/xen14:
kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
memory = 512
name = "xen14${VPSNAME}"
vcpus=1
pae=0
acpi=0
apic=0
vif = [ 'type=ioemu, mac=00:00:00:00:00:00, ip=1.2.3.4 1.2.3.5' ]
disk=[ 'phy:/dev/mapper/lvm1-xen14,ioemu:hda,w', 'file:/var/lib/dtc-xen/ttyssh_home/xen14/boot.iso,hdb:cdrom,r', 'file:/var/lib/dtc-
xen/ttyssh_home/xen14/cd2.iso,hdc:cdrom,r' ]
cdrom="/var/lib/dtc-xen/ttyssh_home/xen14/boot.iso"
boot="d"
vfb = [ "type=vnc,vncdisplay=21,vncpasswd=mYvNcPaSs" ]
nographic=0
vnc=1
stdvga=1
serial='pty'
Note that the above mac address will be calculated and depend on your node name: it will NOT be like the above example.
