10.6.5 Using watches with old versions of CVS

If you use the watch features on a repository, it creates ‘CVS’ directories in the repository and stores the information about watches in that directory. If you attempt to use CVS 1.6 or earlier with the repository, you get an error message such as the following (all on one line):

cvs update: cannot open CVS/Entries for reading:
No such file or directory

and your operation will likely be aborted. To use the watch features, you must upgrade all copies of CVS which use that repository in local or server mode. If you cannot upgrade, use the watch off and watch remove commands to remove all watches, and that will restore the repository to a state which CVS 1.6 can cope with.
