This is better than osxdaily's method (which should only be used for DP1 anyway, not DP4 or the GM):
To make a bootable USB of the GM, use this method:
Your 8 GB USB drive should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Mavericks.app and should be in your Applications folder.
Run this in terminal and wait about 20 minutes:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
You should see something like this:
Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.
You can then boot up from the USB by holding down the option key, then install the GM from the USB.
This is probably going to be the same for the public release.
Note that this will also install a recovery partition (which osxdaily's method doesn't do).
Absolutely, it is always best to obtain the file directly from Apple if you can. However, not all of us are registered developers (myself included). Regardless, I was able to find a download of the GM that is bit-for-bit identical to the download available through the Mac App Store. As long as you use some common sense and download from trusted sources, you will be fine.
P.S. - Please do NOT contact me asking for download links.
You aren't suggesting that it is common sense to download and use software in violation of Apple's License Agreements surely?
You should sign up for the Developer Program and download it from Apple. Only by that method can you be sure that you are getting the correct file and are not violating the License Agreement.
Does anyone know how to put Mavericks on a USB drive so that you can use it to install from?

You mean now or after the release to the public ? Why would anyone want the GM version over the actual public release in a few days ??

Maybe because the public release is the GM?GM = Golden Master, the final build of software given to developers before the same build is released to the public. Barring any major show-stopping bugs found in the build, the GM is the EXACT same thing that will be released to the public. This has been the case for every iOS and OS X release that I can remember.
For those who are not developers or prefer step-by-step instructions, here is how I made a bootable USB drive for the OS X Mavericks GM:
- Obtain a copy of OS X Mavericks GM from the usual sources (torrents, friend with a developer account, etc.)
- The file you download will likely be a .dmg with "Install OS X Mavericks.app" inside. Mount the .dmg and copy "Install OS X Mavericks.app" into your Applications folder.
- Attach an 8GB (or larger) USB flash drive, and open Disk Utility. Select your flash drive in the left column, and then click the "Erase" tab. Format the drive with Mac OS Extended (Journaled) with the name Untitled
- Click "Erase..."
- Close Disk Utility once the process completes. Open Terminal and enter the following command (you can copy/paste):
After you hit Enter, you may be prompted for your password. Type it (the cursor in the Terminal window will NOT move) and then hit Enter again. The process should begin.
- You should see something like this (note that this process can take 15-20 minutes to finish):
Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.
- You can now boot from the USB flash drive by holding the Option key while your computer boots up.
this is strange, followed the directions, it did what you wrote, but the drive did not work.
this was done with GM maverick that was located on external dive - i just changed the path.
Then it's not strange. That's why it didn't work. Don't change the path. In fact don't change anything. Do it exactly as I said and it will work:

Others have added their own complications to it and have asked why it didn't work. Pretty obvious actually.
sudo /Users/your_username/Desktop/Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/aaa/ --applicationpath /Users/your_username/Desktop/Mavericks.app --nointeraction
So did it work for you now?

I have tried this example of making a USB Drive, however it gets stuck at one second remaining, and like in the other post i wait and it reboots, but then all i get is the startup screen, the gong played but then a white screen no logo, so i am assuming that this is the silent install? I have left it either way...
any help appreciated
