I don't think Petr said the hostname hadn't changed.

We recently had to update all of our Root files due to server
relocation.  The old CVS server is still used for a number of other
purposes, so it had to keep its old hostname.  Addressing by name does
not prevent all future issues.

Now, had the old server been originally addressed using an alias (DNS
CNAME) that was used exclusively for CVS purposes, *that* name could
have been transferred to the new server.  (Any problem can be solved by
another level of indirection...)  But the CVS admins didn't think of

Alternatively, here's a Windows cmd script (XP or later) which can be
used to change the server name in the Root file:

@echo off
rem Change all CVS/Root files in or below current directory that
rem point to old-server to point to new-server instead.

setlocal enabledelayedexpansion

for /r . %%f in (Root) do (
   if exist %%f (
      echo %%f
      for /f %%l in (%%~sf) do (
         set root=%%l
         if exist "%%f.old" del "%%f.old"
         ren "%%f" Root.old
         echo !root:old-server=new-server!> "%%f"


Edit it to change the names "old-server" and "new-server" to the old and
new server names.  This script is relatively robust - it handles
directory components with spaces, for example.  (I don't know *why*
anyone would create spacy directories in their CVS repository, but some
of my coworkers have.  Sigh.)
