Hi all, I'm curious. If I do yum update (which include kernel update) but don't reboot. Is it OK? I mean apart of the kernel, other things like services, we don't have to reboot if we don't have the chance to do it (postponing to some other date), right? Thank you.
Hi Fajar, usually you're fine, although i experienced some kind of "binary rot" if I did that too excessively. Especally things that are located "near" the kernel like initscripts and the xen daemon may start acting funny (like domU not starting up any more and such things...) if the kernel version is too far off.> I'm curious.

Unlike MS-Windows, none of the other updates *require* a reboot. Note: if glibc (or other widely used shared libraries) is updated it (they) won't get picked up unless *ALL* of the processes that use it (them) are restarted.> > Thank you. > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > >-- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments

Curious to hear other people's experiences... Cheers Steve
