Rsync fails when not using checksums

[kaspermarkus]

What created the bug:
function do_test {
#make two identical dirs
rm -rf "${GR_LOCALROOT}" "$GR_SERVERROOT"
mkdir -p ${GR_LOCALROOT}{A,B,C}
touch ${GR_LOCALROOT}{A/a1,B/b1,B/b2,C/c1}
cp -r ${GR_LOCALROOT} ${GR_SERVERROOT}
workingdir=pwd;
#initialize repository
./repo_init.sh
echo "change1" > ${GR_LOCALROOT}A/a1
echo "change2" > ${GR_SERVERROOT}A/a1
#make directory locally
./repo_sync.sh
}

Explanation:
The program correctly identifies there is a difference between the files, but when the command is issued to copy (sync) the data one way or the other, the program doesnt seem to realize that the two files */A/a1 differs

Solutions:
Could be handling by using scp instead of rsync, since we know which direction the sync should be in (in the cases i can think of) ... Could also be handed using the -c switch with rsync -- only worry about that is that it is too slow!
