- objcopy/strip changed in 2.36.1, not keeping file attributes of the
original file. Work around that in dh_strip to write to a temporary
file and cat'ing this to the original file to keep the original
attributes.
which is broken for setuid files.

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.
