Frequently asked questions (with answers) on #openbsd IRC channel
Please read the official OpenBSD FAQ
I am writing this to answer questions asked too many times. If some answers get good enough, maybe we could try to merge it in the OpenBSD FAQ if the topic isn’t covered. If the topic is covered, then a link to the official FAQ should be used.
If you want to participate, you can fetch the page using gopher protocol and send me a diff:

OpenBSD features / not features
Here is a list for newcomers to tell what is and what is not OpenBSD
Packet Filter : super awesome firewall
Sane defaults : you install, it works, no tweak
Stability : upgrades go smooth and are easy
pledge and unveil : security features to reduce privileges of software, lots of ports are patched
Has only FFS file system which is slow and has no “feature”
No wine for windows compatibility
No linux compatibility
No bluetooth support
No usb3 full speed performance
No VM guest additions
Only in-house VMM for being a VM host, only supports OpenBSD and some Linux
Poor fuse support (it crashes quite often)
No nvidia support (nvidia’s fault)
No container / docker / jails
Does OpenBSD has a Code Of Conduct?
No and there is no known plan of having one.
This is a topic upsetting OpenBSD people, just don’t ask about it and send patches.
What is the OpenBSD release process?
The last two releases are called “-release” and are officially supported (patches for security issues are provided).
-stable version is the latest release with the base system patches applied, the -stable ports tree has some patches backported from -current, mainly to fix security issues. Official packages are not built for -stable. You have to build them yourself or install them using a third party service like M:Tier
What is -current?
It’s the development version with latest packages and latest code. You shouldn’t use it only to get latest package versions.
How do I install -current ?
- download the latest snapshot install .iso or .fs file from your favorite mirror under /snapshots/ directory
- boot from it
How do I upgrade to -current
- download the latest bsd.rd file from your favorite mirror
- verify its checksum and signature using signify and SHA256.sig file
- rename the old ramdisk kernel as /bsd.rd.old just in case
- copy the ramdisk kernel in its place - /bsd.rd
- type “boot bsd.rd” at bootloader prompt
- choose “U” to upgrade
- reboot after the upgrade process
- pkg_add -u to update your packages
Repeat in order to upgrade to a newer -current snapshot
How do I update packages on my release version ?
Packages are frozen at the release and not updated.
