Under Debian I know I can run apt-get dist upgrade (or something to that effect its been years sorry). i am currently running Fedora 15. Id like to upgrade to the newer vs of Fedora if i can.
[ray@ray Downloads]$ cat /etc/issue
Fedora release 15 (Lovelock)
Kernel \r on an \m (\l)
[ray@ray Downloads]$ uname -a
Linux ray.localhost 126.96.36.199-1.fc15.i686 #1 SMP Tue Nov 29 11:55:17 UTC 2011 i686 i686 i386 GNU/Linux
Is there a safe way to just yum update something like that? or do i need to burn a disk/usb drive and install over the /boot / directories and let it reattach my /home directory (partition)
