I wonder if that means that it's safe to erase since the kernel will regenerate it on boot??

I think so, but way do you want to erase it, it's there for a reason, besides if the kernel automaticly regenerates it, why delete it?

Sorry, I didn't explain that.

I recently updated gcc to 3.4 from 3.3, and after the update I get a lot of error messages on boot that are something like,

Code:

rm&#58; Cannot remove /sys/... &#58; Operation not permitted

(That's from memory)

It repeats this many times for (I think) every file and folder in /sys, so I thought that the kernel attempts to remove and recreate /sys everytime the computer boots, but for some reason was having trouble. If this is the case, then removing it using a liveCD might solve this.

I think I might just temporarily rename the folder and create an empty /sys, just to see what happens. If it kills it, then it would be easy enough to switch back to the backup version.

What do you think?? Am I being smart?? Or am I heading for a world of hurt??

Nope, cause it's easier and works better like this:

Code:

umount /sys

I don't understand. If I umount it, won't it just remount as usual when I reboot?? The boot errors I'm getting would still appear, wouldn't they??

Sorry to bring back a topic that old, but I couldn't find any documentation about the /sys folder online.

Is there a clean way to prevent it from being mounted at startup?
Any place I can find more documentation you guys know of?

Thanks a lot!
