is there a way to enable quota drive spave limits per user ?
in fedora core 5?

absolutely, just google for quota tutorials like this one http://yolinux.com/TUTORIALS/LinuxTutorialQuotas.html

would this be not better in that case if i would make a mount /home ? and just quota this?

then another silly question. If the above case would be great.. is there a way to split drives? at the moment everthing is in 1 partion on a 120gb drive.

or even move the all the fedora from hda to a secound drive, make the secound drive the boot drive and mount the 120gb as /home.. without to have to reinstall all..
sorry but im a complet newbie

well... welcome to "why you shouldn't have a single partition 101"

there are many reasons that having a seperate /home is a must in my opinion, quota's are one, but other things like data preservation over reinstalls is another massive one too.

fedora *should* have actually used an LVM setup ehwn installing, unless you deliberatly told it not to. if you do have lvm then it is very simple to move your /home into a seperate LV using the logial volume manager tool.

you should *always* have a seperate /boot, normally a seperate /home, often have a seperate /usr, /tmp and /var

yep fed got a lvm.. but last time i fumbeled there around i blowed the hole boot away

think if i take the hdc and hda out, reinstall fedora on hdc what is now hda and then copy all from the old hda to the new hda and over write the hole drive it should work..
