You can use info/list/packages-list/packages-info/summary to view what happened, undo/redo/rollback to act on that infor- mation and new to start a new history file. to check that history was enabled, ran 'grep' in /etc and /etc/yum/*, all i found is; yum]$ sudo grep history * [sudo] password for geo: aliases.conf:h history aliases.conf:hi history info aliases.conf:hl history list aliases.conf:hs history summary aliases.conf:hp history package-list yum]$ sudo grep record * grep: pluginconf.d: Is a directory grep: protected.d: Is a directory grep: vars: Is a directory nothing to enable history_record. ran 'yum history', history showed usage 7 thru 26, so no problem. should have done that to start with. as for drive space, diff before and after removal was about 200M in a 14.7GB partition. so no, no advantage, other than a lot of the i686 was also x86_64. reason all this came about was trying to update the x86_64 nss-util and yumex complained about the i686 nss-util. as for rest, like you say, i will find out what i686 i need when i run various progs. another day in my life has been blessed with more learning and a bit wiser.
