On a Windows box with the root directory of a drive being a Subversion
working copy, when the current working directory is in the in the root
directory and your specify the path to update, then it fails:
C:\Documents and Settings\Blair Zajac>svn update e:\
At revision 814.
C:\Documents and Settings\Blair Zajac>e:
E:\>svn update e:\
svn: Working copy 'E:' locked
svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)
Removing the e:\ from the last update has update work.
See this thread for a discussion of the bug:
