Why, after rsync'ing /usr to /tmp-usr, do the sizes differ?

 # du -h --max-depth=0 /usr
3.5G    /usr

and

 # du -h --max-depth=0 /tmp-usr
3.7G    /tmp-usr

Is that because of the different filesystems (ext4 on / and reiserfs on /usr) maybe?

Is there a simple way to get the total # of files and directories for comparison, like you can in Windows when getting properties of a folder?

Still curious about this, but I went ahead and pulled the trigger anyway, and it was about as uneventful as it gets...

Took all of 6 minutes (and almost all of that was rsyncing /usr)...

Made a gentoo forum post in case anyone else wants to do this and may be a little hesitant like I was...

Thanks to all who patiently answered my questions...

I now have /usr merged back into / and no longer have to choose between using an intramfs (which I vehemently did not want to do) and updating my system without fear of breakage.

<whew>
