Ich recherchierte und fand heraus, dass Deep Freeze nicht für Ubuntu verfügbar ist. Gibt es eine Software wie Deep Freeze für Ubuntu 10.04? Verhindern, dass Daten auf die Festplatte geschrieben werden. Ich brauche das, damit ich alles Mögliche auf Ubuntu ausprobieren kann, ohne mir Sorgen zu machen, ob ich die neben ihm installierte Windows-Installation beschädigen könnte. Virtuelle Box ist gut. Aber die Leistung ist nicht. Weil ich nur 2 GB RAM habe.
If you just want to prevent damage to the windows partition you could just unmount it.
If you want to be able to snapshot the ubuntu (or windows) partition the dd command can do that with little fuss.
dd if=/dev/sda1 of=file.img dd if=file.img of=/dev/sda1 CAUTION: The dd command should only be run against unmounted partitions. You can run it from the ubuntu CD if you need the ubuntu partition unmounted.
The closest thing to Deep Freeze for linux would be to create a UnionFS of your actual file system and a tempfs in memory or on a spare partition (memory is limited, but wipes on reboot; spare partition can hold a lot more changes, but must be manually wiped on shutdown/bootup).
If you're worried about accidentally writing to your windows partition, then you should unmount it completely. If you do this, there is very little you could do to your ubuntu partition that would effect it (namely, playing with partition editors or messing up GRUB could still affect it; nothing short of backups can help against partition editors, though the UnionFS approach can prevent against accidentally messing up your boot files.).
