rsync to adapt links that have absolute paths to the location at destination

Would it be possible with rsync to adapt the absolute, symbolic links to a new location at the destination?

Test case
Imagine I have a link pointing to a file like this:

/usera/files/common/test_file
/usera/files/common/links/test_link -> /usera/files/common/test_file

Now I would like to rsync the whole directory common to another location. (group permissions are adapted, look below why)

rsync -av --no-g /usera/files/common/ /userb/common

That gives me:

/userb/common/test_file
/userb/common/links/test_link -> /usera/files/common/test_file

The problem
The problem is that the group on the destination is different than on the source (security reasons), so that the test_link does not point to /userb/ space but rather to /usera/ and therefore is not readable for this user.

Question
Would it be possible to tell rsync to adapt the links below the syncing point (/common/ here) to fit to the new destination? That would give a link as such:

/userb/common/links/test_link -> /userb/common/test_file

I tried following the solution to a similar problem, however it does not seem to do what I want..

Thanks!

Rsync does not support that. It could be modified to do so but rsync already has too many options. You could accomplish your goal by executing this after the rsync:

find /tmp/userb -type l -ls |
awk '$13 ~ /^\/tmp\/usera/ { sub("/tmp/usera/files/", "/tmp/userb/", $13); print $11, $13 }' |
while read A B; do rm $A; ln -s $B $A; done
