That is great, tarsiran! If you want my advice regarding upgrading all the available updates, I would do them one by one in this order:
cd /usr/local/directadmin/custombuild
./build dovecot
when it finish then continue
./build roundcube
when it finish then continue
./build phpmyadmin
when it finish then continue
./build mysql
when it finish continue by recompiling php, wich is always needed after you have upgraded mysql
./build php n
cd /usr/local/directadmin/custombuild
./build dovecot
when it finish then continue
./build roundcube
when it finish then continue
./build phpmyadmin
when it finish then continue
./build mysql
when it finish continue by recompiling php, wich is always needed after you have upgraded mysql
./build php n
