Hi All.
Seth Vidal in this older mail chain below, has mentioned that
RPM no longer supports rollback.
Is this really TRUE, I would like to know the reason why its NOT supported.
I think, RPM currently supports
--AUTOMATIC ROLLBACK OF A TRANSACTION.
ie, what I mean is, if you have multiple package installs/erases within 1 single RPM transaction, then if there is a failure,
for any package install/erase, then prior to failure, whatever other packages that were installed/erased, will be undone. Can someone please confirm this.
Also there is this old link below, that talks about RPMs Rollback feature::
It does say that for upgrade, if repackage option is enabled, then older version of package, including config files, and install scripts will be backed up, under repackage directory(/var/spool/repackage).
So later you can go back to older version, by running this command,
rpm -Uvh --rollback '2 hours ago'
The above URL is 5 years old, and I have RPM 4.4.2.3 version on my Fedora.
So my Qs is, are there issues with RPM rollback feature, as far as when it comes up reverting back to old config files under /etc, and/or if the RPM post/pre scripts create user/system accounts , are there issues undoing those accounts.
Are these the kind of issues, that still linger wrt to ROLLBACK feature.
And as far as AUTOMATIC ROLLBACK, if there is a failure within a single transaction(that has multiple packages), does that feature work fine. OR is that feature also plagued by issues such as reverting config files changes and/or other stuff done from post/pre RPM scripts.
Can someone please let me know.
Thanks very much.
Regards,
Sudha

Hello,
I am willing to contribute for supporting of rollbacks in the packagekit
project with has yum as one of the backends.
I have already joined the packagekit mailing list and I need to know what
kind of work needs to be done for rollback support with yum as backend.
--Regards

Rollbacks aren't supported in rpm any longer, either. I think you'll
find that there is a lot more complexity to rollbacks than you initial
think.

Hi,
I found rpmrebuild which I use to create an rpm prior to running yum.
If I need to "rollback" then I have to delete the rpm and install the
one that
was saved from during rpmrebuild.

And none of this will help if your data has changed as a result of the
upgrade.
