I formatted using ext3. I have to admit this is the 3rd time I am creating a LFS system on a USB stick.
The first was LFS 6.3 kernel 2.6.22.5 with the gpm and lynx packages from BLFS6.3 as well as ClamAV, which I am using as the host to build my 3rd on a 16GB USB stick. (The 2nd was LFS 6.4 on a 4GB USB stick).
I was trying to see if it was possible to create a graphical system without using X. I tried SVGALIB but I just could couldn't get it to compile on my second stick and having mucked around with 3 different kernels I decided to bite the bullet and install X; hence the 16 GB stick.
So what I'm doing is going right back to the beginning and try and fix all the things that looked like problems but didn't prevent the system being built.
I know what you suggest in the book works as I have done that but I was just interested if anyone knew if missing features would be a problem as I don't want to get half way through installing X and have something fail because of something that looked trivial at the beginning.
So I will be posting a lot of questions in the near future
Now I know I'm asking for trouble installing on a USB stick instead of a hard drive but I already have Mandriva installed and I really like the idea of being able to use a system that I have created myself on any PC (well ones that can be booted from a USB stick).
