--- Comment #3 from Edgar Hoch <edgar.hoch@xxxxxxxxxxxxxxxxxxxx> ---
I found the difference in semanage syntax by comparing the manpages fon F19 and
F20 (when looking for the reason why my scripts has failed):

F19: man semanage

       -f, --ftype
              File  Type.    This  is used with fcontext.  Requires a file type
as shown in the mode field by ls, e.g. use -d to match only directories or --
to match only regular files.

F20: man semanage-fcontext

       -f [{a,f,d,c,b,s,l,p}], --ftype [{a,f,d,c,b,s,l,p}]
              File  Type. This is used with fcontext. Requires a file type as
shown in the mode field by ls, e.g. use 'd' to match only directories or 'f' to
match only  regular files. The  following file type options  can  be  passed: 
f  (regular file),d (directory),c (character device), b (block device),s
(socket),l (symbolic link),p (named pipe). If you do not specify a file type,
the file  type  will default to "all files".


I think, the documentation in F20 is sufficient, because it describes how to
call the command semanage fcontext.

My problem was that this is an incompable change in the syntax and that users -
or at least administrators - should be notified that they have to check there
scripts before they move from F19 to F20. The right place would have been the
release notes (or special release notes for administrators).

If the command options isn't described in the security guide until now then it
need not be described only because of this change of the syntax, because the
man page describes the command syntax. But of course, the security guide may
present examples when and how to use semanage fcontext command.


I think there should be a document where additional notes, changes, problems,
etc. can be added to the release notes after release of a fedora version. Think
of the page "Common F20 bugs": it is in the fedora wiki, and it is updated when
there are available new "common" bugs, changes to bugs, etc..

I think fedora need something similar for release notes updates. What do you
think of wiki pages for each released release notes to inform the users and
administrators about additional information, changes, etc., that hasn't found
the way into the release notes before release date? For example, a wiki page
"Release Notes Updates for Fedora 20"?

I know that this has nothing to do with security guide, but I think Fedora is
missing such a release notes updates document, and the problem described in
this bug report is an example that should put into such a document.
