Meanwhile my disclaimer for the contribution has reached Red Hat and the patch will be applied soon. With the new option -s HOME could be set ignoring the blanks, since the filename is converted into 8.3 format: HOME=`cygpath -ws $USERPROFILE` HOME=`cygpath -u $HOME` export HOME > > The presence of spaces in file name and path variables is indeed > problematic.
