linux newbie --help

[srip]

i am a linux newbie.
1: is there a device manager in fedora/mandriva to see if all drivers are recognised after install?
2:what should we do if linux freezes while doing system upadate or something like that.I did a reboot in ubuntu and system became unusable.
3: is it possible to create a checkpoint or something like that while doing system updates etc so that we can rollback to previous state if there is a problem?
4:if we update fedora9 perfect desktop to 10 using yum/preupdate will it work or will it become unstable?how steps to take while updating,like backup etc?
5:how to backup important files in home directory and firefox bookmarks before updating system etc?

1: Dont use Fedora so i cant say if one comes with the distro bu try using yum or an equivalent package manager to download one

2: If it freezes, perhaps go away and give it a significant amount of time to unfreeze if not, you'l just have to reboot.

3: I havent heard of a way to make checkpoints in Linux, just keep an installation/restore disc nearby

4: Updating Fedora 9 to Fedora 10 via yum shouldnt give you any problems and Fedora 10 should run without Issue.

5: Most personal files are stored in your /home directory so just copy that to USB or something similar.

Hope this helps.
