yum update on a Live USB Stick

[Daniel Kirsten]

Hi, 

I transfered the  F10-i686-Live-KDE.iso  to a  2GB USB-Stick (vfat) as 
described on 
http://docs.fedoraproject.org/install-guide/f10/en_US/sn-making-media.html

The stick booted well, but when I tried  make   yum update , yum crashed. 
I got tons of ext3-related error messages, altough the stick has a vfat file 
system. 
After the crash,  I was no longer able to access the stick and dmesg, 
shutdown, ...  did not work. 

Is it generally impossible to make yum update on a live medium, or did 
it fail due to hardware problems?

Thanks,
Daniel
