bsd enforces append only or immutable when the flag is set, not
depending on the securelevel.  there are "user" and "system" flag
sets.  the "user" flag set can be turned off and on at any time by
either the file's owner or root.  the "system" flag set can be set at
any time, but can only be removed when the securelevel is less than or
equal to zero, and can only be set or cleared by root.
