hirsute-amd64.virtualbox_6.1.22-dfsg-2~ubuntu1.21.04.2_BUILDING.txt.gz
I have rebuilt an earlier version of virtualbox, that sets Rules-
Requires-Root: no and added extra ls statements to find where/when/why
setuid bits are getting lost after fixperms.

It seems to me that either dh_strip or something it calls (strip,
debugedit) looses the setuid permission in hirsute and up.
