Hi, I am just looking for some clarification and also reassurance about the following differences in file size of the libkeyutils*.so when reinstalling with yum, and then after upcp runs: libkeyutils.so.1.3 file size: yum = 10192 - upcp = 12592 (CentOS 6.5 /lib64/) libkeyutils-1.2.so file size: yum = 7176 - upcp = 9472 (CentOS 5.10 /lib64/) libkeyutils-1.2.so file size: yum = 6404 - upcp = 7880 (CentOS 5.10 /lib/)
Thanks in advance.

  Is this simply a matter of upcp replacing libkeyutils with a cPanel-specific version? Please confirm.

  Hi cPanelMichael, I had already seen the 'Checking your system status' page, however this is not useful to my question. I am now specifically interested in the difference between the file sizes of the libkeyutils*.so file when installed with just a 'yum reinstall keyutils-libs' command, and then after upcp runs, as per my original post. I have done this repeatedly and the file size consistently increases slightly (again as detailed in my OP) each time I run upcp after reinstalling with yum. All I want to know really is: 'Is it normal for cPanel upcp to install a different, slightly larger libkeyutils file (e.g. /lib64/libkeyutils.so.1.3 on CentOS 6.5) than the default CentOS yum version?' Thanks.

  This sparked my interest. It looks like the change is due to prelinking, so it should be harmless. Running just this after the yum reinstall will have the same effect: /usr/local/cpanel/scripts/rpmup
  You'll notice "info [rpmup] Prelinking shared libraries and binaries: /usr/sbin/prelink -av -mR"

  Hey quizknows, Thank you very much indeed, that makes much more sense now and helps a lot to clarify and alleviate my concern. [Any chance of a cPanel post to confirm quizknows's clever deduction?]

  Yes, it's an accurate description of why the file size changes. You can verify the change in file size after reinstalling a package through YUM by running this command manually (it runs during cPanel updates): /usr/local/cpanel/scripts/rpmup Thank you.
