Optionally, if you have a free partition on any attached drive
that's big enough, you can just write the .dmg to the hard drive
partition rather than burning a DVD. This is common practice for
many Apple engineers. Then you can boot from that partition
rather than booting from the DVD. It's typically much faster
than burning a DVD, too.
Well then you can just leave the dmg as a dmg and just mount it
with hdid (etc) as well too. That is you don't have to expand the
dmg's onto disk.
I don't think you can boot from it in that case, though. And you
need to boot from it to run the installer.
No burning should be necessary. Any particular Mac OS X version
can be installed onto another partition by mounting the .dmg,
logging into the root account and double-clicking on the image's /
System/Installation/Packages/OSInstall.mpkg. You're only required
to boot from a CD/DVD when installing onto your [solitary] boot
volume.
No burning is necessary, but the best way to do this in the absence
of burning or a DL DVD writer is to restore the .dmg to any partition
or drive large enough to hold it, boot from that, and perform the
installation on the desired volume, as was originally suggested.
As Peter noted, while installing directly from the packages may work
in the general case, if there is a newer version of the installer
that is intended to be used, there may be issues if you're not using
the appropriate installer version.
