On daily basis I deploy, maintain and support one of the largest CDNs in the world. I enjoy working on projects involving automation, monitoring, analysing and tweaking *nix system performance, troubleshooting networks, tinkering with virtualisation, etc.

comment How do I increase the hard disk size of the virtual machine?
Well, you need to understand what modifyhd does, which isn't much more than expanding the underlying virtual disk, that's all. You still need to expand the filesystem that's on it.

comment Is there a way to upgrade a machine which is using software raid and LVM to 12.10?
Just wondering - does the plain old apt-get dist-upgrade not work for such purposes in Ubuntu?

revised how to execute for loop with sed in terminal
'for' accepts space delimited values and grep -v '#' would also ignore lines with a hash anywhere in them.

The code you provided as it is won't work - the list of items should be space delimited.

comment Swap encryption and hibernating
Hi Willem, I'm feel like you're trying to solve a problem which I'm not sure exists ;) If someone knows the sda2 encryption password they'll be able to run the machine in single mode anyway and get what they want. If you don't trust the users you share your machine with, then this solution isn't for you. Also there are filesystem permissions, if set up correctly why would guest be able to access your home directory? I don't mean to offend, but I think you might need to reasearch the information about the way Linux/Unix permissions/security is implemented in practice.

comment Swap encryption and hibernating
The decryption password (once per boot) and account password serve completely different purposes. The former is to protect your storage from being mounted by someone and stealing/modifying/etc your data. The latter (account password) is to prevent others to access your machine while the storage is already decrypted. If after you boot, you log in automatically - what's going to prevent others to come by and do whatever they want with your machine? Unless I misunderstood you, this is a really, really bad idea. This way you'd give up all the security you gained by encrypting your storage :)
