Do I have to rebuild my jails too when I rebuild the server?

Yes, run 'mergemaster -D /your_jails_rootdir' from your host. 
Answer the question "Use 'd' to delete the old /var/tmp/temproot and continue" 
with 'd' or simply type 'yes' when mergemaster asks, if you wish to delete 
what is left of /var/tmp/temproot. 

I mostly run a small script that runs installworld, cleans out /usr/include/* 
and runs mergemaster for every enabled jail it finds in /etc/rc.conf. I run 
it on 5.3. The bad thing is, that it depends on ng_rc-style rc.conf, so it 
doesn't work on 4.11. However, if you will ever run 5.3 - feel free to use 
it, modify it or recycle-bin it.
