rpm build on successive days differ in dump command: Nothing changed
Nagrik
I am building rpms on a daily basis. I am actually building more than
22 rpms daily. Out of these 15 rpms do not change on a daily basis
and the following command shows no difference
rpm -qp --dump <rpm name> | cut -d' ' -f1,2,4,5,6,7,8,9,10,11 > /tmp/
file1
rpm -qp --dump <rpm name> | cut -d' ' -f1,2,4,5,6,7,8,9,10,11 > /tmp/
file2
Please note that I am filtering the filed 3, which is the modified
time. However I do include the checksum field. And I expect this
checksum to be identical on two successive days, if nothing changes
for building the command.
After these two commands I do
diff /tmp/file1 /tmp/file2
and show no diff for 15 files.
However, for 7 files (although nothing changes for days and months at
a time) the diff command shows difference. Mainly it lists
some .so, .html and the files listed below.

I also noticed that the size of .so files is exactly the same.
Could someone from the group tell me, what all goes in the rpm and why
exactly it changes for 7 rpms and not for other 15 rpms, because
nothing changes on the successive days for any of these 22 rpms.
I will greatly appreciate this.
Thanks.
