OpenBSD continous integration build machine has two disks. The root image is generated by tools/create-openbsd-gce-ci.sh. This disk is disposable and will be rebuilt when compatibility bumps in OpenBSD-current are encountered. Manual tweaks to this image without updating the script will be lost.
There is also a persistent disk with build artifacts and syz-bot state. It is mounted as /syzkaller. The original image was set up with:
ci-openbsd# fdisk -y -i sd1 Writing MBR at offset 0. ci-openbsd# disklabel -E sd1 Label editor (enter '?' for help at any prompt) > a partition: [a] offset: [64] size: [419424956] FS type: [4.2BSD] > w > q No label changes. ci-openbsd# newfs -m 0 /dev/rsd1a ci-openbsd# mount /syzkaller ci-openbsd# chown syzkaller:syzkaller /syzkaller
Persistent disk structure:
/syzkaller
