Generally, all Linux distributions needs a scheduled reboot once to stay up to date with important kernel security updates. RHN (or other distro vendors) provides Linux kernel security updates. You can apply kernel updates using yum command or apt-get command line options. After each upgrade you need to reboot the server.
This is a loaded question because I'm already aware of, and am very interested in ksplice. The problem is that since they were bought by Oracle, they have been forced to pull numerous server distributions from the offerings.
For many blogs, getting picked up on Slashdot is a dream come true. For startup Ksplice, it seems to be a matter of course. Yes, the company's blog had a total of *three* posts as of Wednesday, and two of them had already hit the big time on Slashdot in short order.
If there is a kernel update from an upstream repository (such as debian or centos) does ksplice work with those updates? If not, how does one update the kernel without a reboot and without paying Oracle?
I know there are solution for not rebooting after kernel update:
But If Ksplice isn't installed, and the user doesn't reboots it's notebook after even several kernel updates (so notebook running for even months). Could there be a problem about it? (not counting that an update probably came because there was a bugfix or security fix)
