I did the following:

As I wanted to get rid of forced fscks on boot up I set my fstab lines to say

... defaults 0 0 except ...defaults 1 1

I probably have to admit that this includes my reiserfs-formatted root disk. (don't know this for sure though)

As from the logs it seems that it came up fine one more time. (I can see starting messages and shut down messages from all services) Although I was told that routing didn't work that time.

I turned the machine back on to check what went wrong and - It was all screwed up. I found out that my fstab-file was down to one line saying.

/dev/hda1 /boot ext2 defaults 0 0

All the rest was gone! (No wonder it didn't come up) I fixed this using the rescue-system. Any ideas on how this could happen? Don't want this to happen agein!!
