"Ksplice: Upgrade / Patch Your Linux Kernel Without Reboots by Vivek Gite · 5 comments 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. Ksplice service allows you to skip reboot step and apply hotfixes to kernel without rebooting the server. In this post I will cover a quick installation of Ksplice for RHEL 5.x and try to find out if service is worth every penny."

netboot.me is a service that allows you to boot nearly any operating system or utility on any computer with a wired internet connection - without having to know ahead of time what you'll want to boot. Once you can netboot.me, you never need to update your boot disk again! In order for your computer to know where to find the netboot servers, you need to change your DHCP settings to return some extra information. The two relevant pieces of information: next-server, which should be "tftp.netboot.me", and "filename", which should be "netbootme.kpxe". How to set these settings depends on your DHCP server. For dhcpd, simply add the following to the relevant 'subnet' section of your configuration: next-server "tftp.netboot.me" filename "netbootme.kpxe" For dnsmasq, the following line in /etc/dnsmasq.conf will achieve the same effect: dhcp-boot=netbootme.kpxe,tftp.netboot.me netboot.me works through the magic of netbooting. There are a number of ways to boot a computer with netboot.me. The simplest is to download a bootable image and burn it to a CD, USB memory stick, or floppy disk. Boot off it on any networked computer, and it will automatically fetch the latest boot options from netboot.me and let you choose from dozens of installation, recovery, testing, portable desktop and other tools. You can also start netboot.me from any computer running gPXE, or from any netbootable computer with some simple tweaks to your DHCP server.
