I know that I can apply the grsecurity patches by compiling my own kernel. This is not a big deal to do it once, but too complex to have regular and easy kernel image updates. So I am looking for linux distributions which supports gsecurity as a kernel-package which I can easily update via a package manager. For Ubuntu there was a repository http://kernelsec.cr0.org/ which was probably trustable because it was linked by the gsecurity page. But it seems to end with kernel version 18.104.22.168.
Since I am currently using ubuntu, it would be great to find something based on ubuntu or just on debian.
