On all the version of unix that I've used you require write
permission to a directory to remove a file from it. Remember its
the file dev on device / that you must update to remove a file !
If you can remove this file just because you own it then you had
better look at the owner and file protection on dev ! NOW !!!!
And get these somebody(s) away from your console !!!!!!
