Create a softraid or svnd encrypted partition with a key from /dev/urandom (without overwriting existing data) 2. Open it. 3. Create a new ffs filesystem on it. 4. Mount the new ffs filesystem, async most likely. Well, it's a horribly convoluted idea, not at all elegant like an mfs or a tmpfs, but if one doesn't mind the long boot time while OpenBSD creates the new ffs filesystem, it ought to work.

It states: "The wsfb driver uses whatever graphics mode the console is set to (by Mac OS) as a dumb unaccelerated framebuffer in 8 bits per pixel. You should be able to use 'startx' or xdm to start X without further configuration. "To use xdm from rc.conf, it is necessary to disable /dev/ttyC0 in /etc/ttys, change the 'status' of /dev/ttyC0 to 'off'." I don't want to use xdm from rc.conf. I want to start it from the console on an as-needed basis. I don't actually like X.org. I find it annoying and bloated, but nonetheless, a necessary evil. Thus, I don't want it to start when my computer starts: I want to call on it when I have need of graphical programs.

A bit below, but now it works. I'm quite happy with stable. Unless current fixes my X11 keyboard issues, I'd rather not deal with current unless I have a second hard disk to play with. I suppose if I ever temporarily need more space in /tmp I'll just have to set up a softlink to /var/tmp or somewhere. However, is there any way to get mfs to use swap first rather than memory first? I'm just trying to make it take advantage of the swap encryption (random keys unlike a single key I have to remember the password for); I don't really need speed improvements and certain excessively bloated applications like Firefox and Gimp, which I might occasionally want to run, could really use the memory. >> Also, is there any way to switch consoles?

Not as convenient as separate consoles, but it does the job. And, with one tmux terminal displaying the output of pdisk and another running disklabel, I was able to manually tell disklabel where the Linux partitions were so OpenBSD and Linux could share swap and ext2/3 home. For some reason, OpenBSD did not seem able to find the Linux partitions automatically like it could on x86, even when I tried re-installing OpenBSD after Debian. Unfortunately, once I start X11, I don't know how to get out, short of rebooting the computer. This is very inconvenient when X crashes, or I can't click the exit button in fvwm because the faulty keyboard driver things I'm holding down the arrow down key even though I'm not. For the record, X seems to crash in framebuffer mode, but not in ati/radeon accelerated mode. In framebuffer mode, even running some xterm program, like top, might kill it, although it seems more likely to die on me if Firefox is running. Changing the driver seemed to fix mouse issues. (Whatever it had by default, sometimes I would lose control of the cursor and it would go toward the bottom of the screen.) I haven't figured out the right driver for the keyboard. If I tell xorg.conf to use kbd or akbd, it doens't work at all, but if I tell it to use keyboard, sometimes it randomly decides not to notice that I've pressed certain keys, and is particularly reluctant to recognize the backspace key. Sometimes, it becomes convinced I am holding a key down even when I am not: this is particularly annoying when it thinks I'm holding the down arrow key. None of these issues occur when not running X.org. Running X -configure crashes the system, and not even Ctrl+C or Ctrl+Z was able to uncrash it, so the configuration had to be done manually. -BEGIN PGP SIGNATURE- Charset: UTF8 Version: Hush 3.0 Note: This signature can be verified at https://www.hushtools.com/verify wsBcBAEBAgAGBQJN1ATLAAoJEKlMTST7VF+omA0H/iRSQ3inWMcin+0d9nB9odznLVTD nh73vTCqSFpNJSaeu4hW4mJENlzbBA9C2ioy5vg1XKjxTeqXFIl2QHLiCrdGLBEB/C36 bBQd+3WKbisRzpeJOTRh7Oaqo1fEmSPdEOo2a3vlHqWDo1kUgp3maguHlzSHZN+4L0IG Biuh7bN5jwPAgV7WM5Ne3fQPNM02kS6mP7gw/WJQP1XY6C5H0u+MqHjGNl80X+tKtZuy b5owR2k5RbciOOK+pZ10t2fcWCumd4rtPMlmI4KsG09IP60Vffmf8ve5WAGOyzcxlZmy W2zhCEc7Poi/ub7OaxftN829eQSNIBXeF/zwvoObPi0= =WPkG -END PGP SIGNATURE-

[assuming this is still macppc] 2097152 x 512 (bytes per sector) = 1GB Up to OpenBSD 4.9, MAXDSIZ on macppc is 512MB so you will be limited to -s=1048576 or slightly below. In -current it has been bumped to 2GB so you'll be able to use more there. > Also, is there any way to switch consoles?

No separate consoles, you will need to use tmux or similar (or X of course).
