Oddities in Windows ACL inheritance

[Nicolas RUFF]

Hi all,

Let's have a look at Windows 2000/XP ACL inheritance oddities :
1/ Create a new file named "test.txt"
2/ Break ACL inheritance and apply custom ACL
3/ Rename "test.txt" to "othertest.txt"
4/ Check that ACL has not changed

Now :
1/ Use REGEDIT and create a new key (in HKCU for example) named "key"
2/ Break ACL inheritance and apply custom ACL
3/ Rename "key" to "newkey"
4/ ACL has been reseted and is now inherited from parent !

It looks like the "rename" paradigm does not make sense for registry
keys and REGEDIT has to create a new key, copy values, and delete the
old key.

Bug or feature ?
