I’ve started some work to test the contents of some configuration files in nixpkgs, but I’m running into a strange issue:
machine: waiting for file ‘/etc/pam.d/chfn‘
(0.02 seconds)
cleanup
kill machine (pid 8)
machine # qemu-system-x86_64: terminating on signal 15 from pid 6 (/nix/store/fkzla307l4mlcvfyshsrccwl7szihx2z-python3-3.9.6/bin/python3)
(0.02 seconds)
Traceback (most recent call last):
File "/nix/store/xry4g85wdm7jq0fwg7bx41l2zshi1cdz-nixos-test-driver/bin/.nixos-test-driver-wrapped", line 1334, in <module>

exec(self.tests, symbols, None)
File "<string>", line 4, in <module>
FileNotFoundError: [Errno 2] No such file or directory: '/etc/pam.d/chfn'
So machine.wait_for_file("/etc/pam.d/chfn")
on line 3 succeeds but open("/etc/pam.d/chfn")
on line 4 fails. What gives? I tried machine.send_chars("ls -lA $(readlink -f /etc/static/pam.d/chfn)\n")
followed by machine.screenshot("foo")
, and the target file is there, readable by everyone. I also tried open
ing with mode rb
, but no go.
What am I doing wrong?
