Hey,

i wonder if its possible to use dnf and dictate it to not install packages that are younger then $((today - 7 )) for example.
If not directly possible, any other ways to accomplishing it?
Sure, building repos with snapshots would work here but I am
looking for additional ways ...


A couple ideas:

1. You could run weekly from a scrpt:

yum --assumeno update

which will create the transaction (but not install it) and save it to /tmp/ and then rerun that transaction week later:

yum --assumeyes load-transaction /tmp/yum_save_tx.2021-11-14.13-54.FhQii3.yumtx


That's an interesting approach. Not sure if this is still valid for EL8?
Some tests doesn't show any transaction artifact. Maybe I need to dive deeper ...



2. Write a yum plugin to mask packages from the transaction sack that are less than 7 days old. How are your python skills?

That seems to be the cleanest solution. Lets see if I find time for that. A quick look into repodata xml files shows that the build time
is also there exposed ...

Thanks,
Leon
