I would like to make a bootable DMG or ISO file with OS X Mavericks on it. I want to then burn this file to a DVD-ROM (or, alternatively, make a bootable USB stick with it).
From what I've read, however, the file
/Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg
is not bootable. From what I understand, to make it bootable one needs to insert a file called BaseSystem.dmg inside InstallESD.dmg and then burn the resulting DMG (perhaps after converting it to an ISO 9660 file, although I'm not sure whether this is necessary) to a DVD-ROM drive.
Here is what I'd like to know:
What exactly is BaseSystem.dmg?
Is this file the same on all OS X systems? Will any version of this file from any OS X system do just as well?
Do I need to use Disk Utility to add this file to InstallESD.dmg or can I use the command line? What is the procedure in each case?
I am not root on the system. Can I accomplish this without a root password? I've heard the root password is only needed for setting file permissions. Can I get away with this, copy BaseSystem.dmg, and do the rest of the work requiring root privileges on Linux after mounting the USB key with all files on Linux?
