See the Ubuntu LiveCD page for details. This page just outlines the steps particular to the iHRIS LiveCD

Source

The image used to create this CD is stored on ihrisdev under /home/mah/ihris-live. Use rsync to copy the structure there to your work area.

  sudo env SSH_AUTH_SOCK=$SSH_AUTH_SOCK rsync -a --numeric-ids \
           --progress hrisdev.intrahealth.org:/home/mah/ihris-live/ ihris-live/

Scripts

I've written a few simple scripts to automate some of the tedious steps. These are located directly under ihris-live:

edit-chroot

This will drop you into a properly configured chroot that is, for all intents and purposes, the filesystem that the LiveCD will use. After you exit, you'll be returned to your command prompt.

NOTE: If you try to run MySQL from chroot, you'll run into problems if you already have an instance of MySQL running on your workstation since it will try to listen on the same port. Other processes, like Apache will also cause conflicts. make-iso

After running edit-chroot, use this script to create the ISO.

The other scripts should not be necessary for regular use.

Of Note

A user is created from the contents of /etc/skel when the LiveCD begins running. Anything you put in here will be in the LiveCD user's environment. Here is a list of notable modifications to this environment:

Mark's Image

R-Kiosk plugin

A .mozilla directory is set up with the R-Kiosk plugin installed. I had to edit the .mozilla/firefox/d0i2gqoj.default/extensions/{4D498D0A-05AD-4fdb-97B5-8A0AABC1FC5B}/install.rdf file and change em:maxVersion from “3.0” to “3.0.*” to get the kiosk plugin to work on boot-up

.xsession file

Firefox is started without a window manager running. When it exits, the user is (currently) returned to the GDM login screen.

EOP Image

It is on hrisdev:~/litlfred/eop_live_dvd.tar.gz (gzipped w/ -rsyncable) It is based on mark's image with the changes as detailed below. I updated make-iso to clean out the log and temporary files.

  • under chroot:
    • apt-get install flashplugin-nonfree evince
  • created edit/usr/share/i2ce/lib/3.0
  • unpacked the ihris-suite-full-3.1.4.tgz in edit/usr/share/i2ce/lib/3.0
  • database setup chroot:
    • kill mysqld before chroot.
    • sudo ./edit-chroot (the rest of this bullet is under chroot)

      • in .mozilla/firefox/d0i2gg0j.default/pref.js:
        • added in "user_pref("toolkit.networkmanager.disable", true);" so that firefox does not keep switching to work-offline mode
      • in .mozilla/firefox/d0i2gg0j.default/extensions.ini:
        • removed the line enabling the r-kiosk
      • changed examples.desktop to:
