minimega: "-hashfiles -headnode" flags prevents mesh file sharing

[glattercj]

Describe your environment

1. minimega 2.9 da0b90c 2024-09-04
2. Ubuntu 22.04
3. n/a
4. KVM

Describe the bug
When starting minimega with the flags -hashfiles -headnode=xxxx on a multi-node deployment, minimega will not pull files across the minimega mesh specified by -filepath=<filepath>.

To Reproduce
Steps to reproduce the behavior:

1. Deploy minimega on n1 and n2 with flags -hashfiles -headnode=n1
2. Start a KVM instance on n2 (not the headnode) and run miniccc on the VM
3. Create a file on the headnode in the filepath directory <filepath>/foobar
4. Try to send a file via miniccc using minimega -e cc send <filepath>/foobar

Expected behavior
The file should be sent successfully to the VM running on n2 by first pulling the file to n2 over the mesh.

Hmm I just tried this and it seemed to work as expected? Followed the steps you gave above, plus mesh dial n1 on n2 since otherwise mesh list was empty.

Here's the output (on n2). Confirmed the file was on the VM as expected.

Do you have anything else in your logs?
