I came to the problem that I needed to test native linux/unix virtualisation recently. First, I tried to think of the new test box I have to procure, but then I got the idea that I'm not using my current resources to the full: my MacBook Pro i5 8GB RAM. Found this (see a copy in my Google Drive). It was really easy!
All you need is to do reEFInd bot manager and install Ubuntu afterwards. Worked like a charm! And it is very nice performance of Ubuntu on this metal :)
The only annoyance was that my computer stopped to do sleep normally (from OS X perspective). It needed hard reboot every time after a few hours of sleep. Fortunately, upgrade to Yosemite solved this, probably just a fresh reinstall of anything would have helped.
Enjoy!

shellshock on my systems - no real worries
To determine if your Linux or Unix system is vulnerable, from a command line, type something like this:
env x=’() { :;}; echo vulnerable’ bash -c “echo this is a test”
If the system is vulnerable, the output will be:
vulnerable
this is a test
An unaffected (or patched) system will output:
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x’
this is a test
or it will say that bash is not present or something else, you figure it out :)
So what about my systems? Here's the list:
env x=’() { :;}; echo vulnerable’ bash -c “echo this is a test”
If the system is vulnerable, the output will be:
vulnerable
this is a test
An unaffected (or patched) system will output:
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x’
this is a test
or it will say that bash is not present or something else, you figure it out :)
So what about my systems? Here's the list:
- pfSense firewall 2.1.4-RELEASE (amd64), built on Fri Jun 20 12:59:50 EDT 2014, FreeBSD 8.3-RELEASE-p16 : not vulnerable, bash is not there by default :) check /etc/shells if you have it installed
- FreeNAS home server FreeNAS-9.2.1.7-RELEASE-x64 (fdbe9a0), FreeBSD 9.2-RELEASE-p10 #0 r262572+4fb5adc: Wed Aug 6 17:07:16 PDT 2014 : bash present by defeult, system vulnerable, checked jails, bash not present, will wait for the fix in next version, there's good comment on this at the end of this discussion :)
- Mac Darwin Kernel Version 13.3.0: Tue Jun 3 21:27:35 PDT 2014; root:xnu-2422.110.17~1/RELEASE_X86_64 x86_64 : vulnerable, (I think) I haven't played with enabling/opening things, so will be waiting on Apple :)
- Hackintosh Darwin Kernel Version 13.3.0: Tue Jun 3 21:27:35 PDT 2014; root:xnu-2422.110.17~1/RELEASE_X86_64 x86_64 : vulnerable, (I know) I haven't played with enabling/opening things, so will be waiting on Apple
- XBMC based HTPC on Ubuntu 14.04.1 LTS, Linux ___ 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux : not vulnerable
- I haven't hacked into my TV and I won't :)
Good luck to you all!

dealing with consequences of upgrading to mavericks
Installation process went without errors, the only issue was that notice "will complete in less than minute" stayed for at least 20 minutes while preparing installation.
I didn't took time, but something like an hour in total.
Side thought: given install size 5+ GB remembered that ubuntu hit size of 1 CD just recently :) so, wondering what's in: code or pictures ;)
As +Andrejs Prokopjevs scared me about gmail, first checked if it works at all: I can receive and send emails.
NFS mounts doesnt work:
* mount folders are gone from Volumes
* in Finder it gives you error message: problem... share doesnt exist on server...
* NFS Manager doesnt do automount
Started to investigate by simply showmount in terminal: took a long time, minutes... after that everything seem working. no problem - no need to solve it :) just recreated mountpoints manually.
Hmm, after restart my mountpoints are gone again -> will try to use NFS managers mountpoint autocreate feature, works for first trigger.
Cisco vpn works.
Citrix Receiver doesn't work out-of-the-box. There is Mavericks ready 11.8.2 version in their website, but simply installing it didnt help me. Restarted Mac, now it works :)
[MS Lync for Mac asked to be updated to 14.0.6; I let it. Annoyance again: "install time remaining: less than a minute" stayed for couple of minutes on the screen]
Force Quit function is gone from dock... Apple, really?
Default search engine for Safari is Yahoo :D
Now, Java. As I'm Oracle eBS user: 6 version it is. Get Java, I did here. After install id didn't work out of the box, even after restart. I remembered about this. Just trying to just copy and paste - it didn't work for me out of the box either. Then I looked into what I really do and fixed it. It seem that Mavericks understands symbolic links differently. Actual pieces and folders are the same. Restart just for sure :)
