12 We need do this because we changed the behavior and the new behavior is
13 counter-intuitive. We already had a number of bugs caused by it,
14 and while it's used by Infra, it's at least unexpected when someone
15 manually runs 'repoman manifest'.
17 I mean, before this all started 'repoman manifest' just updated
18 the Manifest which meant it's mtime changed. Nowadays, it also sets
19 mtime to some value in the past, which means running 'repoman manifest'
20 may result in updated Manifest having mtime older than the old
21 Manifest. As a result, people using rsync are in trouble. And this has
22 been reported too by overlay owners.
