For the sake of anyone else curious about what that means, here's what
man ar told me when I looked up the details:
D Operate in deterministic mode. When adding files and the archive
index use zero for UIDs, GIDs, timestamps, and use consistent file
modes for all files. When this option is used, if ar is used with
identical options and identical input files, multiple runs will
create identical output files regardless of the input files'
owners, groups, file modes, or modification times.
If binutils was configured with --enable-deterministic-archives,
then this mode is on by default. It can be disabled with the U
modifier, below.
...
U Do not operate in deterministic mode. This is the inverse of the D
modifier, above: added files and the archive index will get their
actual UID, GID, timestamp, and file mode values.
This is the default unless binutils was configured with
--enable-deterministic-archives.
So Fedora has opted to --enable-deterministic-archives.
(I offer no opinion on the virtue or vice of that choice.)
Eddy.
