all of the above
and stressing that fedora is a VERY fast development distro
14 will be out in about 1 month .then 30 DAYS after that fedora 12 hits " end of Life"
"E of L" means NO SUPPORT, no updates, no nothing -- it is dead .
so every 6 months you really do need to do a fresh clean install of the NEW version
or risk having to fix a few things and use " preupgrade" to the next version
READ and REREAD the fedora docs
the wiki can help
but the forum is VERY helpful
register there and read and ask questions
also DangerMouse has a nice page
and Mjmwired has a very nice "quick reference " page
