Hitchhiker's Guide to Openbsd

partition. While this is often 
quite useful, it doesn't satisfy all users' needs. 
For our example, we'll assume we are building a static web server for some of our friends to use. We have a machine 
attached to a modest Internet connection, with a 40G disk, with most of it used for OpenBSD (with the same 5G 
Windows partition as the example above. Why? Maybe this system has a RAID controller which is supported by

OpenBSD, but manageable only from within Windows. More likely, because the FAQ editor doesn't feel like maintaining 
lots of different example systems). 
The web pages served by an OpenBSD web server will be in 
/var/www
, and very little will be stored in 
/home
, so this 
indicates a definite change from the default that needs to be made. For the sake of discussion, we'll also assume that we 
won't need to rebuild the OS from source on this machine (we'll do that elsewhere). The system will not run X, however 
being that some web applications 
expect X to be installed
, we will have X installed. The machine is not overly powerful, 
it can't have more than 1G RAM in it, and it is unlikely our application will ever desire more than that. 
So, after a bit of thought, our plan is to partition the system like this: 
●
/ - root
: 100m. This will be 'a'. 
●
swap
: 1G (so we'll always have enough space for a core dump), this will be partition 'b' 
●
/usr
: 2g, partition d 
●
/tmp
: 100m (we don't anticipate much use of this), partition e 
●
/usr/local
: 2g, partition f 
●
/usr/X11R6
: 1g, partition g 
●
/home
: 1g, partition h 
●
/var
: 1g (that's a lot of system log files), partition j 
●
/var/www
: rest of disk, partition k 
The auto-allocated layout for wd0 is:
# size offset fstype [fsize bsize cpg]
a: 1024.0M 10490445 4.2BSD 2048 16384 1 # /
b: 252.1M 12587597 swap
c: 39205.7M 0 unused
d: 2319.3M 13103933 4.2BSD 2048 16384 1 # /tmp
e: 3653.9M 17853877 4.2BSD 2048 16384 1 # /var
f: 1149.8M 25337016 4.2BSD 2048 16384 1 # /usr
g: 1024.0M 27691862 4.2BSD 2048 16384 1 # /usr/X11R6
h: 3422.6M 29789014 4.2BSD 2048 16384 1 # /usr/local
i: 5122.3M 63 NTFS
j: 1848.7M 36798433 4.2BSD 2048 16384 1 # /usr/src
k: 1848.7M 40584654 4.2BSD 2048 16384 1 # /usr/obj
l: 17540.2M 44370875 4.2BSD 2048 16384 1 # /home
Use (A)uto layout, (E)dit auto layout, or create (C)ustom layout? [a] c
If we had only minor revisions, we'd probably opt to "Edit" the custom layout rather than starting from a clean slate, but 
we are going to do things the hard way here.
