Install a package from -current version?
I am using the release version of OpenBSD 5.7 with the latest patches. I suppose it is called stable version? Can I download packages from the "snapshots" version and install them on my stable version without bricking my system? What is the sudo command to accomplish it?

OpenBSD is an integrated whole, an entire system. Mixing & matching is neither recommended nor supported. As a newcomer to OpenBSD, you will find a lot of information, including answers to many common questions in the official FAQ. Taking the time now, while beginning, to study will save you significant time & aggravation later on... |

I would also recommend purchasing Absolute OpenBSD.

My definition of "stable" is exactly the same as in http://www.openbsd.org/faq/faq5.html#Flavors:

There are, however, some fixes occasionally checked into the -stable branch which are not deemed to be significant enough to warrant standalone patches made available on the errata page. As an equation, the following is actually what can be found in CVS: Quote:

1. Is it sufficient for me to just apply whatever is on the Errata page to the --release version in order to have a secure (that is not vulnerable), hardened and stable (as opposed to unstable) operating system? 2. --If I don't apply the stuff that you called "fixes in the CVS's diff"--will my operating system consisting of only --release+errata become insecure (that is vulnerable) and unstable? |

Your question has now been clearly answered no less than three times. Your provided link to faq5 explains it clearly in fact.

Prove to me that you're right by quoting the relevant sections from http://www.openbsd.org/faq/faq5.html#Flavors that directly answer my two (2) questions. |

Please, people. Let's all remain civil. We're trying to share knowledge, and that's all. While the word "discussion" and "percussion" may have similar etymologies, can we please not traverse the path from one to the other?
--- The -stable CVS branch is tagged simultaneously with -release during the development cycle. Unlike -release, which remains static, this branch will receive patches as needed for reliability, availability, and security. If a -stable fix is deemed to be of broad interest or sufficient severity, an errata patch will be published on the Project website. It is possible to have a fix developed and deployed for -stable that does not receive publication as errata. It may be deemed non-critical, or determined to have limited impact. If so, this won't be a security fix, those are always critical. Is there a difference between -release+errata patches when compared with -stable? The answer is sometimes. Does it matter which you choose? For security, no. |

I meant no offense and I hope none has been taken.
Thanks for the answer on security. What about stability of the OS if I don't apply the "fixes in the CVS diff"? |
|

No idea what you mean by "stability of the OS". Read the section on the stable or "patch" branch and on anoncvs if you want to know more.
Also read faq15 and faq9: http://www.openbsd.org/faq/faq15.html http://www.openbsd.org/faq/faq9.html |

I'll try to clarify where I think there may be confusion.

You are correct in stating that the FAQ does not make this clear, however, careful mining of the project's mailing lists will reveal my statements to be true. |

General security can be had by properly running a -release installation with relevant patches. However, "being secure" is not simply a matter of applying errata patches. An improperly managed system, be it OpenBSD or any other operating system, can result in a system which is insecure. What the project maintains is that OpenBSD, as installed by the installation process, is pretty gosh darn secure. How people fiddle with permissions, or install unknown applications, or share passwords is completely out of their control. Security takes constant vigilance. Applying patches helps, but being aware of the fallout of daily usage is important too. Studying the project's FAQ will help guide behaviors, & it will also help shape your questions. Over time, you will develop a better feel for what is not a black & white subject. |

An OS is described as being unstable when it crashes often resulting in users having to reboot their machines. In Microsoft Windows OS for example, OS instability often results in BSOD (blue screen of death). In Unix and Unix-like OSes, it's called "kernel panic".
