Simplifying map syntax

Simplifying map syntax

automount recognizes the ``&'' and ``∗'' characters as having a special meaning within maps. Using these characters as string substitutions within automount maps reduces redundancy in each line of a map and saves a user from having to duplicate information. 

Ampersand (&)

Suppose you have an indirect map with a lot of subdirectories specified, for example: 

   john                         moscow:/home/moscow:john
   mary                         moscow:/home/moscow:mary
   joe                          moscow:/home/moscow:joe
   able                         prague:/export/home:able
   baker                        sydney:/export/home:baker
                [.  .  .]
Consider using string substitutions. If the string in the ``key'' field is repeated in the ``location'' field, you can use the ampersand character (&) in place of the key value string wherever it appears in the ``location'' field.

Using the ampersand, the above map now looks like: 

   john                         moscow:/home/moscow:&
   mary                         moscow:/home/moscow:&
   joe                          moscow:/home/moscow:&
   able                         prague:/export/home:&
   baker                        sydney:/export/home:&
                [.  .  .]
Suppose the name of the server is the same as the key itself, for instance: 
   moscow                       moscow:/home/moscow
   sydney                       sydney:/home/sydney
   prague                       prague:/home/prague
   milan                        milan:/home/milan
   zurich                       zurich:/home/zurich
                [.  .  .]
The use of the ampersand results in: 
   moscow                       &:/home/&
   sydney                       &:/home/&
   prague                       &:/home/&
   milan                        &:/home/&
   zurich                       &:/home/&
                [.  .  .]

You can also use key substitutions in a direct map: 

   /usr/man                     moscow,seattle,zurich:/usr/man
This could be written as: 
   /usr/man                     moscow,seattle,zurich:&
Notice that the ampersand substitution uses the whole key string, so if the key in a direct map starts with a ``/'' (as it should), that slash is carried over, and you could not do something like this: 
   /progs                  &1,&2,&3:/export/src/progs
This is because automount interprets it as: 
   /progs     /progs1,/progs2,/progs3:/export/src/progs


Asterisk (∗)

Notice that all the entries in the ampersand indirect map examples have the same format. This permits you to use the usual substitute character, the asterisk (∗). The asterisk reduces the whole thing to: 

   ∗       &:/home/&
Here each ampersand is substituted by the value of any given key. This tells automount to mount /home/server from any known server.

Once automount reads the substitute key, it does not continue reading the map, so that the following map is viable: 

   milan           &:/export/&
   zurich          &:/export/&
   ∗               &:/home/&
In the next map the last two entries are always ignored: 
   ∗               &:/home/&
   milan           &:/export/&
   zurich          &:/export/&

Q.  Is there a recertification policy for the MCITP certification?

A.

We no longer require a "refresh" or recertification of the MCITP certification within three years. To better meet our customers’ needs, we now retire a certification when mainstream support for the related technology phases out. If you earned an MCITP certification before the policy change, no action is required—the updated policy applies to your certification, which will remain valid until mainstream support for the related technology ends.

 

Q.  Does MCSA equate to MCITP: Server Administrator and does MCSE equate to MCITP: Enterprise Administrator?

A.

No, not exactly. The MCITP on Windows Server 2008 certification requires a new skill set—in some cases, a more robust one—that differs from the skill set needed for MCSA and MCSE certifications.

  •  

    MCITP: Server Administrator certification covers more operations-related job skills than the MCSA certification.

  •  

    MCITP: Enterprise Administrator maps to an actual job role profile, whereas the MCSE certification does not. The latter combines technology and job skills.

 

Q.  Are the MCTS and MCITP certifications replacing the MCSA and MCSE certifications?

A.

No. The MCSA and MCSE certifications are not being replaced. There is no change to the Microsoft Windows 2000 Server and Windows Server 2003 tracks and certifications. The MCTS and MCITP certifications are for Windows Server 2008.

 

Q.  Am I a Microsoft Certified Professional (MCP) if I earn an MCITP certification?

A.

Yes and no. The term MCP is used both as a general term for all Microsoft Certified Professionals and as the name of a certification. As an MCITP, you become part of the Microsoft Certified Professional community, with access to all related benefits, information, and activities. You do not earn a certification titled "MCP." You should use the MCITP certification on your resumé and in business collateral, which indicates your specialty and shows that you are a member of the MCP community.

 

Q.  How long will my certification be valid?

A.

All Microsoft Certified Technology Specialist (MCTS), Microsoft Certified IT Professional (MCITP), and Microsoft Certified Professional Developer (MCPD) certifications retire when Microsoft discontinues mainstream support for the related technology. After a certification retires, it still appears on your transcript but is listed as "inactive." In most cases, an upgrade path is available for people who have that certification, which allows them to demonstrate their skills on the newest version of the technology without completing all exams associated with the new certification. The following certifications will not be retired: Microsoft Certified Systems Engineer (MCSE), Microsoft Certified Systems Administrator (MCSA), Microsoft Certified Desktop Support Technician (MCDST), Microsoft Certified Database Administrator (MCDBA), Microsoft Certified Solution Developer (MCSD), and Microsoft Certified Applications Developer (MCAD).
