Is it important to reboot Linux after a kernel update?
- by lfaraone
I have a few production Fedora and Debian webservers that host our sites as well as user shell accounts (used for git vcs work, some screen+irssi sessions, etc).
Occasionally a new kernel update will come down the pipeline in yum/apt-get, and I was wondering if most of the fixes are severe enough to warrant a reboot, or if I can apply the fixes sans reboot.
Our main development server currently has 213 days of uptime, and I wasn't sure if it was insecure to run such an older kernel.
