Did you diff the text files?
The files other than those in /usr/bin I know the cause of their alteration. It is caused by my ssh accesses.
Did you "binary diff" the binaries?
No
How many bytes difference? constant number?
prelink???
It seems so:
[root@vhost01 ~]# yum install gdb . . . [root@vhost01 ~]# ll /usr/bin/gdb -rwxr-xr-x. 1 root root 4453160 Dec 7 2011 /usr/bin/gdb [root@vhost01 ~]# mv /usr/bin/gdb /usr/bin/gdb.cln [root@vhost01 ~]# cp -p /usr/bin/gdb.cln /usr/bin/gdb [root@vhost01 ~]# ll /usr/bin/gdb* -rwxr-xr-x. 1 root root 4453160 Dec 7 2011 /usr/bin/gdb -rwxr-xr-x. 1 root root 1061 Dec 7 2011 /usr/bin/gdb-add-index -rwxr-xr-x. 1 root root 4453160 Dec 7 2011 /usr/bin/gdb.cln lrwxrwxrwx. 1 root root 3 Jul 4 14:16 /usr/bin/gdbtui -> gdb [root@vhost01 ~]# prelink -v /usr/bin/gdb Prelinking /usr/bin/gdb [root@vhost01 ~]# ll /usr/bin/gdb* -rwxr-xr-x. 1 root root 4468992 Dec 7 2011 /usr/bin/gdb -rwxr-xr-x. 1 root root 1061 Dec 7 2011 /usr/bin/gdb-add-index -rwxr-xr-x. 1 root root 4453160 Dec 7 2011 /usr/bin/gdb.cln lrwxrwxrwx. 1 root root 3 Jul 4 14:16 /usr/bin/gdbtui -> gdb
Which accounts for the size changes as far as I can see. I infer that the linked sizes likely changed as a result of system library updates associated with the recent kernel update.
Thank you for the help.
I do not think prelink would alter text configuration files like .Xauthority or .bash_history
Those files I expected to change and I am aware of the the cause. It is only the files in /usr/bin that concern me.
