on a test system, i ran "yum list updates" and got 400+ packages for which there are updated versions in the repos. (as a quick example, at the end of the list, i verified that i have ypbind-1.12-2 installed and ypbind-1.12.3 in the repository. so far, so good.) so i run # yum update and i get a slew of messages of the form [update: <package> <version>] ... Is this ok [y/N]: i type "y", hit return, looooooooong pause with much disk activity, then "Calculating available disk space - this could take a bit" ... another long pause and more disk activity, then numerous lines of output: installing package <blah> needs xxyyMB on the /usr filesystem where the numeric value "xxyy" is clearly increasing slowly and finishes at 286MB. there's about 525M available on /usr, and i don't get an error message but when it's done, nothing's been updated, nothing in the log file /var/log/yum.log. am i missing something? why was nothing updated? running "yum list updates" again shows the same 400+ packages that are available for updating. thoughts? rday
