Hello mates,

As you know, in arch Linux the kernel is updated frequently but, is mandatory or good practice reboot any time the kernel is updated?

Edit: Thank you guys for your replies

An update is only truly done once no remnants of the old code is in memory. Code can stick around in the form of binaries (restart the binaries), libraries (restart all binaries that use this library) and the kernel (reboot or use kexec).

One very simple way to make sure no old code sticks around is to reboot:-)
