The coding you provided switches MariaDB to mysql since it upgraded to mysql 5.5 ,itd be equal to service restart mysql knowing that on official it was mysqld so all in all there is no mysqld anymore.I bet you have got under your belt of tricks another coding like that in order to switch from nginx to apache and from this like I also have succesfully installed on my machine php5.2.17 all ala 32 bit ,I wonder if installation did something so kloxo works with it since some fpm, versions might not work.
What would be cool would be that installation dont delete httpd 2.2 then I just turn MariaDB to mysql and maybe switch for an fpm to php52.17 or choose compatible fpm and just switch nginx to apache that would keep my 2.2,and I say this lo because in the past on kloxoMR7 switching from nginx to apache truly didnt brought me to anything real
