OS X Mavericks: InstallESD.dmg and BaseSystem.dmg 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?


Thanks.
The Mavericks installer comes with a tool to make bootable installer. Just use 

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
