[Arch Linux] qubes-mount-dir not starting start in R3.2 - chgrp on absolute symlinks

[ptitdoc]

Qubes OS version (e.g., R3.2):

R3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

potentially all templates

---

Expected behavior:

Template boot properly with last qubes-agent

Actual behavior:

Template boots but qubes-mount-dirs does not start. Because of that /home/ is empty and gui-agent fails

Steps to reproduce the behavior:

Create an absolute symlink in the AppVM home pointing to a file in /home (or event an invalid symlink ?) and reboot

@ptitdoc What template are you using? Is it Arch?
This seems to work with both Debian and Fedora templates, and I cant reproduce the issue following your instructions.
Please amend title and set labels appropriately

Yes this occured on archlinux, however I cleaned up the invalid links before testing with other templates.

Based on the error, I through that the problem would be the same on any linux template. I will check if I can reproduce it on other templates.
