I created a guide to help explain the issue, what is needed why it's needed now more than ever with an example of Docker's Kali container.

This fingerprint database is adapted from Michal Zalewski's p0f passive
operating system package. The last database sync was from a Nov 3 2003
p0f.fp.
Each line in this file specifies a single fingerprint. Please read the
information below carefully before attempting to append any signatures
reported as UNKNOWN to this file to avoid mistakes.
We use the following set metrics for fingerprinting:
- Window size (WSS) - a highly OS dependent setting used for TCP/IP
performance control (max. amount of data to be sent without ACK).
Some systems use a fixed value for initial packets. On other
systems, it is a multiple of MSS or MTU (MSS+40). In some rare
cases, the value is just arbitrary.
NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
value of nn is not fixed (unlikely), just copy the Snn or Tnn token
literally. If you know this device has a simple stack and a fixed
MTU, you can however multiply S value by MSS, or T value by MSS+40,
and put it instead of Snn or Tnn.
If WSS otherwise looks like a fixed value (for example a multiple
of two), or if you can confirm the value is fixed, please quote
it literally. If there's no apparent pattern in WSS chosen, you
should consider wildcarding this value.
- Overall packet size - a function of all IP and TCP options and bugs.
NEW SIGNATURE: Copy this value literally.
- Initial TTL - We check the actual TTL of a received packet. It can't
be higher than the initial TTL, and also shouldn't be dramatically
lower (maximum distance is defined as 40 hops).
NEW SIGNATURE: Never copy TTL from a p0f-reported signature literally.
You need to determine the initial TTL. The best way to do it is to
check the documentation for a remote system, or check its settings.
A fairly good method is to simply round the observed TTL up to
32, 64, 128, or 255, but it should be noted that some obscure devices
might not use round TTLs (in particular, some shoddy appliances use
"original" initial TTL settings). If not sure, you can see how many
hops you're away from the remote party with traceroute or mtr.
- Don't fragment flag (DF) - some modern OSes set this to implement PMTU
discovery. Others do not bother.
NEW SIGNATURE: Copy this value literally.
- Maximum segment size (MSS) - this setting is usually link-dependent. P0f
uses it to determine link type of the remote host.
NEW SIGNATURE: Always wildcard this value, except for rare cases when
you have an appliance with a fixed value, know the system supports only
a very limited number of network interface types, or know the system
is using a value it pulled out of nowhere. Specific unique MSS
can be used to tell Google crawlbots from the rest of the population.
- Window scaling (WSCALE) - this feature is used to scale WSS.
It extends the size of a TCP/IP window to 32 bits. Some modern
systems implement this feature.
NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
to zero or other low value. There's usually no need to wildcard this
parameter.
- Timestamp - some systems that implement timestamps set them to
zero in the initial SYN. This case is detected and handled appropriately.
- Selective ACK permitted - a flag set by systems that implement
selective ACK functionality.
- The sequence of TCP all options (MSS, window scaling, selective ACK
permitted, timestamp, NOP). Other than the options previously
discussed, p0f also checks for timestamp option (a silly
extension to broadcast your uptime ;-), NOP options (used for
header padding) and sackOK option (selective ACK feature).
NEW SIGNATURE: Copy the sequence literally.
To wildcard any value (except for initial TTL or TCP options), replace
it with '*'. You can also use a modulo operator to match any values
that divide by nnn - '%nnn'.
Fingerprint entry format:
wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
wwww - window size (can be *, %nnn, Snn or Tnn). The special values
"S" and "T" which are a multiple of MSS or a multiple of MTU
respectively.
ttt - initial TTL
D - don't fragment bit (0 - not set, 1 - set)
ss - overall SYN packet size
OOO - option value and order specification (see below)
OS - OS genre (Linux, Solaris, Windows)
Version - OS Version (2.0.27 on x86, etc)
Subtype - OS subtype or patchlevel (SP3, lo0)
details - Generic OS details
If OS genre starts with '*', p0f will not show distance, link type
and timestamp data. It is useful for userland TCP/IP stacks of
network scanners and so on, where many settings are randomized or
bogus.
If OS genre starts with @, it denotes an approximate hit for a group
of operating systems (signature reporting still enabled in this case).
Use this feature at the end of this file to catch cases for which
you don't have a precise match, but can tell it's Windows or FreeBSD
or whatnot by looking at, say, flag layout alone.
Option block description is a list of comma or space separated
options in the order they appear in the packet:
N - NOP option
Wnnn - window scaling option, value nnn (or * or %nnn)
Mnnn - maximum segment size option, value nnn (or * or %nnn)
S - selective ACK OK
T - timestamp
T0 - timestamp with a zero value
To denote no TCP options, use a single '.'.
Please report any additions to this file, or any inaccuracies or
problems spotted, to the maintainers: lcamtuf@coredump.cx,
frantzen@openbsd.org and bugs@openbsd.org with a tcpdump packet
capture of the relevant SYN packet(s)

WARNING WARNING WARNING
-----------------------
Do not add a system X as OS Y just because NMAP says so. It is often
the case that X is a NAT firewall. While nmap is talking to the
device itself, p0f is fingerprinting the guy behind the firewall
instead.
When in doubt, use common sense, don't add something that looks like
a completely different system as Linux or FreeBSD or LinkSys router.
Check DNS name, establish a connection to the remote host and look
at SYN+ACK - does it look similar?
Some users tweak their TCP/IP settings - enable or disable RFC1323
functionality, enable or disable timestamps or selective ACK,
disable PMTU discovery, change MTU and so on. Always compare a new rule
to other fingerprints for this system, and verify the system isn't
"customized" before adding it. It is OK to add signature variants
caused by a commonly used software (personal firewalls, security
packages, etc), but it makes no sense to try to add every single
possible /proc/sys/net/ipv4 tweak on Linux or so.
KEEP IN MIND: Some packet firewalls configured to normalize outgoing
traffic (OpenBSD pf with "scrub" enabled, for example) will, well,
normalize packets. Signatures will not correspond to the originating
system (and probably not quite to the firewall either).
NOTE: Try to keep this file in some reasonable order, from most to
least likely systems. This will speed up operation. Also keep most
generic and broad rules near the end.

This needs to be investigated. On some systems, WSS
is selected as a multiple of MTU instead of MSS. I got

Windows TCP/IP stack is a mess. For most recent XP, 2000 and
even 98, the patchlevel, not the actual OS version, is more
relevant to the signature. They share the same code, so it would
seem. Luckily for us, almost all Windows 9x boxes have an
awkward MSS of 536, which I use to tell one from another
in most difficult cases.

There were so many tweaking tools and so many stack versions for
Windows 98 it is no longer possible to tell them from each other
without some very serious research. Until then, there's an insane
