What I'm trying to do is revert my VPS running OpenBSD-current (following via binary updates, using snapshots and booting to ramdisk) to OpenBSD-6.2-release.
It's not an important system, so if it gets borked, I'll start over. However, I'd like to not set it up from scratch because I do use it.
If I boot to ramdisk (boot: bsd.rd), then follow the upgrade process, however, I replace the path to the new -current image with the path to the 6.2-release image, will I have many problems? Following that, I would obviously change PKG_PATH to reflect the change to -release, and update the packages accordingly.
I'm assuming I won't have many problems, even if this is not advised and not supported, because I'm not jumping major version numbers (ie. current has not advanced to -6.3 yet, so it's essentially "upgrading" to an older binary snapshot of -6.2)
