I have updating my fedora 10. However, I am looking at the manual pages on update. However, there is some words I don't understand.
--obsoletes flag 'does this mean it will update packages that are now obsolete? Why is it better for distro-version changes?
What is a shell glob?
update If run without any packages, update will update every currently installed package. If one or more packages
are specified, Yum will only update the listed packages. While updating packages, yum will ensure that all
dependencies are satisfied. If no package matches the given package name(s), they are assumed to be a
shell glob and any matches are then installed.
If the --obsoletes flag is present yum will include package obsoletes in its calculations - this makes it
better for distro-version changes, for example: upgrading from somelinux 8.0 to somelinux 9.
