#2It's not just a bunch of people setting cm.swappieness to 0 is it? That behaviour changed and now prevents going into swap /ever/ where it used to mean go into swap as a last resort. Changing it to 1 fixes the issue and will act like the old behaviour or only swapping as a last result.
Regardless, it's things like this why we never recommend people use Ubuntu - years of poorly packaged and tested software. If you want a Debian based system use Debian (and accept that there's now a lot of missing packages are barely any proper SELinux or clustering support) or use RHEL/CentOS for a more complete district and add in repos like epel and elrepo as required.

Can you please share your experience a bit more ? How much SELinux is really required ? What about grsecurity.
My use case is custom build Django/Postgres app.

Centos/rhel are on a pretty old kernel at this point though?

grsecurity is enhancing the security of the kernel itself, SELinux is for user space applications.

What the hell? What happened to "don't break userspace"?

Yeah, Ubuntu still keeps running out of space in /boot by filling it w old kernels in the default partition profile. A bug that I've been hitting since about 2011.
In spite of their best efforts, it is not the "grandma friendly" quality software it hoped to be.

I didn't mess with swappiness, but I also didn't have a swap.

You can run `apt-get autoremove` and it will purge old kernels/headers for you (amongst any other no-longer-used dependencies).

If we're sharing Ubuntu bugs, how about the one where NFS with Kerberos had been completely broken since several years back. You simply can't mount such a share, and you'll always get an authentication error.
I reported it as soon as I upgraded (to 14-something I think) and the bug was marked as severe. Every time a new release of Ubuntu comes out I check if it had been fixed, and of course it hasn't.
