CONTAINER:/tmp$ tectonic test.md
error: Read-only file system (os error 30)
caused by: Read-only file system (os error 30)

I am running in /tmp which has write access... any ideas? Can't seem to get any more logs out of the system either. The user has read-only access to other directories.

try running with strace and see which syscalls fail:

strace -f tectonic test.tex

(I saslo noticed your file has md extension, is that intended?)
