Hello Masatake YAMATO,
Thank you for the followup.

sbuild/schroot can use different mechanisms, but in this case / is
overlayfs (the underlying fs is ext4):
unstable-amd64-sbuild on / type overlay (rw,relatime,...)
ls -la /etc/passwd

I have applied abd93fcecfbb1a1fac7032fac9d2903c5d2d3a38 alone, which
does not help in my case (DEV[STR] is 0 instead of 1).
I have also applied #1595 in full in a second build, see output
below.
Many thanks,
Chris
