            Bug ID: 234031
           Summary: loader can't traverse filesystem, LUA ERROR: cannot
                    open /boot/lua/loader.lua
           Product: Base System
           Version: 12.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern

Booting from a clean copy of /boot obtained from
FreeBSD-12.0-RELEASE-amd64-bootonly.iso does not work. The BTX loader seems to
have issues traversing the filesystem - when I poke around with 'ls', it sees
the root, but can't enter subdirectories. The system disk uses BSD/UFS scheme.
The loader however has no trouble browsing the storage disk, which is GPT/UFS.

This has been previously reported a month ago in CURRENT as bug #233098 but was
miscategorized and no additional info was provided. The issue is currently
being discussed in
https://forums.freebsd.org/threads/lua-error-can-not-open-boot-lua-loader-lua.68635/

I am currently working around this by booting off of the iso, then mounting the
system disk. Interestingly, /dev/ada0 exists but dev/ada0a doesn't, and 'gpart
list' does not even mention ada0. No idea what this means. I ran fsck just in
case, all filesystems are clean.
