    packaging: setup: ignore sack cache populate errors
    
    for some reason yum when going to cache only mode tries to download
    online repositories, and if fails cause the entire transaction to fail.
    
    more over, when going online, it also tries to download online
    resources, and if fails cause the entire transaction to fail.
    
    any network issue during this stage will create an undesired failure. so
    just ignore these errors and hope for the best, as this sequence is only
    used when transaction is rollbacked.

commit 160ab4edb5b176e626fca4dd3e748e3397b01db0

    packagers: yum: do not use yum state strings
    
    the yum.i18n produces non standard string encoding, encoded using ansi
    codec but has unicode string, while the locale environment is set to
    unicode, and python does enforce proper unicode in string.format().
    
    the solution is to provide our own translation table for transaction
    status, as no [simple] way was found to convert the non standard format
    into unicode.
