Re: Fwd: yum rollback !!

hi tim ,
well ya i agree with u ,.... i had this in mind , because once we erase the
package, the system may become inconsistent , degrading the whole idea
behind having the rollback functionality . so any further suggestions ?

and ya Fajar, i actually was reluctant to use yum in my first
implementations of the scripts , but didn't think of a better method given
my low knowledge, ..... actually using storage and providing backup and
recovery was a option i already had, .... but my point was to design it to
be very simple to use and a very 'swift' application ........

Thanks
