Hello Michael, gluu-server package consist of 2 parts. **gluu software** and **chroot environment**. **gluu-server-3.1.2-1-4.rhel7.x86_64.rpm** = **gluu software** + **rhel7 chroot environment** **gluu-server-3.1.2-1-4.centos7.x86_64.rpm** = **gluu software** + **centos7 chroot environment** gluu software is the same for all packages but chroot environment is different. So package size is depending only from chroot environment which is not affecting gluu-server functionality as it depends only from gluu software. Here is extracted .rpm packages contests. gluu software is located under /opt and /install directories. As you can see size for /opt and /install is equal for 2 packages. **rhel7** ``` 0 bin 604K boot 8.0K dev 13M etc 4.0K home 2.2M install 0 lib 0 lib64 4.0K media 4.0K mnt 461M opt 4.0K proc 40K root 128K run 0 sbin 4.0K srv 4.0K sys 32K tmp 764M usr 351M var ``` **centos7** ``` 0 bin 93M boot 8.0K dev 32M etc 4.0K home 2.2M install 0 lib 0 lib64 4.0K media 4.0K mnt 461M opt 4.0K proc 32K root 120K run 0 sbin 4.0K srv 4.0K sys 32K tmp 774M usr 77M var ``` Please let me know if you need more info about this

Thank you for the response. One other question: Is there any expected problems from using the gluu-server-3.1.2-1-4.centos7.x86_64.rpm on a RHEL7 operating system?

Thanks for question, There is no any expected problems and most likely it will work. But anyway we recommend to run centos7 package on centos7 OS as we test it only on centos7.

Thank you, This case can be closed.

Thank you as well. Closing the ticket.
