now some of these errors do say what is wrong in a way that syas how to fix - 
expected uid etc. but others say that a directory is world readable but not 
what the proper perms should be, the error about the cd command not being 
found, well i tested, and it works :)
i suspect that a lot of these errors come from keeping my /var partition which 
has all my mail on it, but not all of them surely
i the former case should i do a reinstall formatting everything but /home or 
is there a way to get msec to make the corrections it knows about?
