greetings.

today i attempted to update update for the nss-util. i selected the x86_64, clicked apply, error message popped up showing a conflict because the i686 was also installed.

opened yumex to see what i686 was installed and found a bunch of i686.

because system is a dual core 64 bit, i decided to remove all i686
packages, programs first, then lib files.

during reboot, thought hit that there may be some i686 packages that should have been left in. maybe for wine.

this is same system that due to fresh install problems, i installed via 64 bit live dvd.

in “closing the gate after the horses have left the corral”, i am asking is what i did good or bad.

tia.

  • If you try to run a program and it doesn’t run, then removing i686 might have been bad. Wine is definitely one that will pull in a long list of i686 dependencies.

    Generally what I recommend is this: If you install a package that you then decide you don’t want, use “yum history undo” or “yum history rollback” to remove that package. Otherwise, just upgrade and don’t look for things to remove. The amount of disk space used by packages you don’t actively use is measured in cents. Your time is worth far more.
