To manually add sessions to KDM in Archlinux, do the following:
cd /usr/share/apps/kdm/sessions
You will see *.desktop files of many, many window managers and desktop environments. Obviously, unless you have all of these on your system, many of them are "just there." To add a session, simply copy any of the preexisting *.desktop files and modify it to suit your need.
In my case, I copied openbox.desktop to awesome.desktop and replaced "Exec=openbox" with "Exec=awesome."
As OpenBSD101 notes, "USB drives usually show up as (emulated) SCSI drives."
But, how do you know which drive? You have two choices. First, you can take a look at the console output. If you insert the drive at the XDM login stage, the console will react, and the output will be preserved following your login. Second, you can type dmesg | grep sd, and it will tell you which sdX device is associated with the flash drive. In my case, it was /dev/sd1. So, as root, I did the following:
mkdir /mnt/flashdrive
mount /dev/sd1i /mnt/flashdrive
To mount an OpenBSD root slice in GNU/Linux, first create a folder.
sudo mkdir /mnt/openbsd
Then, run the following command:
sudo mount -r -t ufs -o ufstype=44bsd /dev/hdb5 /mnt/openbsd
The key is to locate the OpenBSD root slice in Linux. To do so, type dmesg | grep bsd in a terminal emulator. This will list the devices that are associated with BSD.
