Remove DACLs Default ACLs also on directories using: 
	setfacl -bk ~/.[!.]* ~/.[!.]*/**/ ~/.[!.]*/**/* \
			/???/**/ /???/**/* /sbin/ /sbin/*
- that takes a while to run, and you may get a few anonymous
	setfacl: Permission denied
messages - paths in the messages would have been nice here!

Be careful *NOT* to hit Windows directories including your Windows 
home directory, or any other Windows directories, native symlinks, 
native hardlinks, junctions, or file types such as Windows .lnk, 
.URL, etc. where Windows may rely on the DACLs, ACLs, and attributes 
for proper handling.

I don't know that removing them would cause problems, but I don't 
trust Windows to DTRT if it doesn't see what it expects, or DTRT in 
future if changes are made and the expected settings are not still 
in place.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
