In the process of updating my copy of the CentOS 7 (1503) -01 install media, I notice that it's ~70MB larger than the image that it's replacing:
$ rsync mirrors.kernel.org::centos/7.1.1503/isos/x86_64/*DVD*.iso
-rw-r--r-- 4310695936 2015/03/31 17:05:50 CentOS-7-x86_64-DVD-1503-01.iso -rw-r--r-- 4236247040 2015/03/28 12:15:26 CentOS-7-x86_64-DVD-1503.iso
But when I compare sizes using "du" on the mounted ISO files, I can't see any discernible difference:
Original CentOS 7 (1503) DVD:
$ du -ks /centos7/* 1 /centos7/CentOS_BuildTag 6148 /centos7/EFI 1 /centos7/EULA 18 /centos7/GPL 79428 /centos7/images 73378 /centos7/isolinux 281423 /centos7/LiveOS 3752743 /centos7/Packages 12696 /centos7/repodata 2 /centos7/RPM-GPG-KEY-CentOS-7 2 /centos7/RPM-GPG-KEY-CentOS-Testing-7 3 /centos7/TRANS.TBL
Revised CentOS 7 (1503) -01 DVD with centos-release fix:
$ du -ks /centos7-01/* 1 /centos7-01/CentOS_BuildTag 6148 /centos7-01/EFI 1 /centos7-01/EULA 18 /centos7-01/GPL 79428 /centos7-01/images 73378 /centos7-01/isolinux 281423 /centos7-01/LiveOS 3752745 /centos7-01/Packages 12696 /centos7-01/repodata 2 /centos7-01/RPM-GPG-KEY-CentOS-7 2 /centos7-01/RPM-GPG-KEY-CentOS-Testing-7 3 /centos7-01/TRANS.TBL
Seems like a large delta in ISO size for not much of a change in content. Any ideas?
