Hello friends, i had posted about Yum roll back a little time ago, well i actually went on and applied for GSoc , with the same idea, and then i could see all the inconsistencies and backdrops which were not very inherent initially ,i have also been having discussions on the official YUM mailing lists, and here are my findings ,......
1) the utility would be very slow if it used YUM again for the rollback process also 2) i was suggested to use conventional backup and recovery methods, and try improving the backup storage methods and improve the speed eventually . 3) the system would be left very inconsistent , if the rollback process anywhere involved the use of commands such as 'rpm -e' or 'rpm -e --nodeps, and the second command is even more dangerous . 4) important : the yum log file does not take notice of downgraded changes , which are sometimes done with YUM 5) all the changes done to the system by RPM scripts may not be undone . i have thinking of some new ideas which i will very soon put up for discussion , well frankly i am against the idea of using the conventional backup and recovery method, but have to give that a thought as well , i will also be updating constantly my discussions at GSoc on my blog at www.satisheerpini.blogspot.com!
