I like having separate partitions (or slices) for everything. The guy who introduced me to UNIX did it so he could mount certain filesystems "ro" or "noexec". He also told me that partitioning can help avoid inode exhaustion but I really doubt that is an issue with modern filesystems. I still partition with NetBSD. It just feels right; even if not necessary.

I never run out of disk space, but I frequently run out of inodes. It's definitely still an issue. And if you don't stop to think about when you're creating your file system, it tends to bite you in the arse at a later date.

Out of curiosity, can you share what platform/file system you generally use? I had assumed inodes would not be an issue with modern operating systems; especially 64-bit ones.

Perhaps I'm the only person using computers in 2016 who only installs OpenBSD via CD :-)

I only do to enjoy the pleasure of old ways. Interacting with CDs and CD drives reminds me of when it was cutting edge. Tray mechanics, the speed intake of spinning motors. Even the latency and seek sounds. And somehow, the (almost since it's on DVD RW) immutability. In some ways, the sheer speed of SSD is ... boring when you're not in a hurry. ps: a bit like vynil lovers who take their player out for similar reasons…

I can recommend an offline install of Debian using the DVD1, DVD2 and DVD3 binary iso images. No need for an Internet connection.

Depending on the software you wish to install, you will be swapping between the DVDs a few times (e.g. texlive/gnuplot/r-base).

So far as I am aware, Debian is the only distribution that provides a fair chunk of the packages available in the (main) repository for effectively offline installation.

On traditional Unix filesystems, a fixed number of inodes is provisioned when a filesystem is created. Though of course the upper bound on that is limited by the width of the numeric type ino_t (or whatever plays that role in kernel space) have you, in practice, the actual limit is lower.

I'm looking at a filesystem I have handy here; the root FS in an Ubuntu Linux VM. dumpe2fs /dev/sda1 says that the inode count is 1146880. Just a million and something: way less than what a even a 32 bit inode number can represent.

That filesystem simply cannot have more objects than that, in total.

With this type of filesystem, you have to estimate how many objects you will ever need to store in it, not only how much total storage. If you estimate too high, you waste inodes. Suppose inodes are 128 bytes wide and you provision four billion of them. Oops, that's like half a terabyte of storage dedicated to the array of inodes!

For those of you who are looking at a reason to play around with openBSD, there might be some progress at getting it to run at the Raspberry pi 2 and 3: http://marc.info/?l=openbsd-cvs&m=147059203101111&w=2 Probably not going to happen, but it runs on some other ARM7 SBCs. Mine is running FreeBSD currently, but where is the geek cred in that?

this is currently being worked on as I type this reply :)

_nice_.

For my pi I want something that I don't have to think about. A colleague pwned my rpi because I hadn't updated it in ages. OpenBSD seems like a better choice...

Oh, I partition too, but I do /, /usr, /var, /var/log, /home, /tmp, /opt (yeah, yeah, I know), and then anything server specific (mail, maybe www). I just don't do the /usr/local.

When I set up NetBSD, I create /, /usr, /var. /tmp, and /home. I have never create a /usr/local partition but I can see value in it is you want /usr itself to be read-only.

I do /var/log because of some bad experiences with runaway programs - samba went psycho on me in the 3.x days.

It is - I did not know this. I purchased a USB-DVD player for the sole purpose of getting a physical delivery of OpenBSD. Sad to see it go by the wayside.

I can't tell if this is a joke.

Which part - buying a USB/DVD player just for OpenBSD? In three+ years that's literally the only thing I've used it for. Nothing else.

The part about OpenBSD 6.0 not being on CD? I have no idea - this is the first I heard about it. Couldn't really find anything on the site either other than the song lyrics referenced above...

I do that too. I also like to imagine a post-apocalyptic, no-internet time where I have a generator, PC, BSD disk and the knowledge to use them to rule the new world while everyone else is stuck on the "Activation Required" screen.

Fortunately OS X isn't as bad as Windows. I haven't tried the most recent version, but for previous versions I have successfully installed OS X from a USB stick, without needing any internet access at all.

However, the OS X binaries are signed. So, when the key expires, people are SOL. I had this problem, and easily re-downloaded my various older OS X versions. But in the general case it's quite disturbing: http://www.macrumors.com/2016/03/03/older-os-x-installers-br...

CDs are read-only, whereas a USB stick has (generally insecure) firmware that can be modified. So in a setting where the user is concerned about persistent USB malware, it can make sense to use them. It's a niche concern of course, but I suspect it's a little bit more common in the OpenBSD community than in many others. Of course it shouldn't be too hard for those users to build their own install boot CDs with the ta…

What happens if your cd that comes in the mail is swapped out for a different cd by a malicious actor?

They get caught.

SLE (and RHEL) do too, and I think that openSUSE Leap does as well (but I don't think that it's visible from the main download page).
