rebase on remote branch

hi first I know rebase on remote branch is bad idea so I am here asking for suggestions if you can kindly provide some

in my server I got two branches , master and release , and release is branched from master

0---0---0---0-- master
        \
           0---0-- release

our work mainly focus on master, so we will keep committing code to master for some reasons, release branch is for others, and it has some commits that master doesn't have

and now in every week, we have some stable code in master branch so we also want the release branch also has these new code

0---0---0---0---*---*---* master
        \
           0---0-- release

how should we do now??

currently our way is doing rebase in our local pc

0---0---0---0---*---*---* master
                                    \
                                      0'---0'-- release
in release branch
$>git rebase master

but in that way when we want to push the release branch back it will fail because it's non-fast-forward updates so we doing git push -f origin release to force it to 'rebase' on our remote server

or if we use cherry-pick model

0---0---0---0---*---*---* master
        \
           0---0---*---*---* release

but in this case , how do we do it in script? I mean, how do we know we need to start cherry-pick from the 1st '*' to the 3rd '*' in master

more precisely , if A to E represents the commit SHA1

0---0---0---0---A---B---C---D---E master
        \
           0---0---A'---B'---C' release

the 3 cherry-picks A' B' C' on release branch won't have the same SHA1 for A B C in master how can we know effectively we need to start cherry-pick from C to E on master

thanks
