Comment 2 Zdeněk Pavlas 2013-06-13 14:17:34 UTC

The problem is that:

1) since commit 0f03409 (Tue Dec 13 15:43:30 2011) users always have their own cachedir (even when -C is in use)

2) The -C option instructs Yum NOT to attempt any modification of the cachedir.

As a result, preloading from root to user cachedir does not work when user runs "yum -C .."  I wrote a patch to fix (some cases of) this, but it's not upstream.  It's also questionable whether it's a bug or not.  See this thread:

Comment 3 James Antill 2013-06-18 20:01:19 UTC

 Yeh, not much has changed since that thread. In theory we can change .cache = 1 to mean "no network activity" and declare all past API usage of cachedir=<system>, cache=1 as broken/bad ... but we should really have done that sooner.
 From what I can see all current yum-utils scripts "behave" and wouldn't trigger this problem.


 Maybe putting the access() check from the thread:

http://lists.baseurl.org/pipermail/yum-devel/2013-June/010175.html

...into a property (cached) and using that to say "can't modify" instead of cache=1 would be quick and have no downsides (push it and se^W run ;).

Reviewed the dependency on #903631 and assessed it to be a duplicate.
