Shirt Pocket Discussions - Found a strange problem with image restore

Ok

I just started my first test (btw thanx for all your answers Dave)

My environment:
MacBook Pro 15" (unibody)
3 partitions
1st MacOSX (installed SnowLeopard, that's the live one)
2nd Test (installed SnowLeopard, that's the test system)
3rd Data (for DATA only)

What have i done:
Startup from Test
I created a backup of MacOSX partition with SD 2.6.1 (read/only compressed image).
Then restored the dmg with DiskUtilities
Boot from MacOSX and opened the terminal, in the terminal i get the following text before i get the prompt

Quote:

dyld: shared cached file was build against a different libSystem.dylib, ignoring cache.

prompt:~ administrator$

So this doesn't look good!, what more problems can i expect?!?
So i decided to restore the dmg using SD and bootup again, open the terminal and everything looks OK now!

Questions:
1. Why do i get this error in the terminal (when using diskutilities to restore the image)?
2. Do i ALWAYS should use SD restore an image?

Appreciate all your replies
