Looking at the output in 
https://autobuilder.yocto.io/pub/repro-fail/oe-reproducible-20201219-fqxxqel9/packages/diff-html/

you can see that the .text section in the binary changes size. Ignoring
the offset changes, the actual change is the change in size of
the maybe_emit_login_defs_warning function from 256 to 275 bytes.

That function is in the systemd sources in git/src/sysusers/sysusers.c.

It uses a variety of configuration options such as:

SYSTEM_ALLOC_UID_MIN
SYSTEM_UID_MAX
SYSTEM_ALLOC_GID_MIN
SYSTEM_GID_MAX

My best guess is that we're not setting one of these and its falling
back to a host system value which varies by host distro.

Obviously we need to prove that and figure out the correct value for OE
usage but its maybe a pointer as to the possible problem (or I could be
totally wrong!).

Cheers,

Richard
