Permissions always get messed up?

[faroZ06]

Does this only happen to my cousin and me, or does this happen to everyone? When I repair my permissions with Disk Utility, I get errors that it fixes (not ACL things, "permissions differ" errors). It finishes, supposedly fixing everything. Then I run it again the second after I just fixed everything, and it has more stuff to fix. On top of that, it didn't fix my music and Mail settings I didn't have permissions for because of a manual user migration.

If repairing permissions results in error messages, some of these messages can be ignored and should be no cause for concern.

Mac OS X: Disk Utility's Repair Disk Permissions messages that you can safely ignore​

Some people repair, or recommend repairing permissions for situations where it isn't appropriate. Repairing permissions only addresses very specific issues. It is not a "cure all" or a general performance enhancer, and doesn't need to be done on a regular basis. It also doesn't address permissions problems with your files or 3rd party apps.

Five Mac maintenance myths
About Disk Utility's Repair Disk Permissions feature​

Disk Utility repairs the permissions for files installed by the Mac OS X Installer, Software Update, or an Apple software installer. It doesn’t repair permissions for your documents, your home folder, and third-party applications.

You can verify or repair permissions only on a disk with Mac OS X installed.

Does Disk Utility check permissions on all files?

Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked. For example, if you install an application using a non-Apple installer application, or by copying it from a disk image, network volume, or other disk instead of installing it via Installer, a receipt file isn't created. This is expected. Some applications are designed to be installed in one of those ways.

Also, certain files whose permissions can be changed during normal usage without affecting their function are intentionally not checked.

Troubleshooting permissions issues in Mac OS X​

Yeah, I'm getting some of those Java permissions errors. What's weird is that after it fixes them, I run it again, and it's instantly off again. I have no choice but to ignore them.

Also, "Disk Utility repairs the permissions for files installed by the Mac OS X Installer, Software Update, or an Apple software installer. It doesn’t repair permissions for your documents, your home folder, and third-party applications." Shouldn't that include the default folders in the home folder it gives you? It was so bad that I couldn't open iTunes. Opening iTunes even gave me a KP before I went in and fixed the permissions myself.
