Not sure where to go with this one.
I don't know specifics relating to the "legal" requirements (likely country-specific) regarding the need for, and language contained in, any verbose login notification screen's text, in
- /etc/issue, and
- /etc/issue.net
(and anywhere else that would be required) so that there would be enforceability of any pursuit for legal redress as a natural consequence for any non-authorized outsider's breaching/accessing of any individual's private computing devices.
As a starting point for the discussion, I include here my own version of such a file's content, based only on my own sense of fair warning.
Text for /etc/issue and /etc/issue.net:
Please note, this is a private, home-based, personal-use destop computer
and NO external access is deemed authorized, for any purpose!

1) ABANDON THIS CONNECTION IMMEDIATELY !!!
You do not have a legal right to access this system or its contents.
2) This system has no material of legitimate interest to anyone other than the
individual owner of this system.
3) This system (hardware, software and network) and installed services are private,
for personal use of this individual owner and access is restricted to this single
authorized user.
4) All activities performed on this system are recorded and anyone contacting,
accessing or using this system does so with EXPRESSED CONSENT to all monitoring
or examination that is undertaken upon detection of such activities.
5) Since there are NO instances of legitimate external access granted, for ANY
purpose, all usage by anyone other than the individual owner is deemed illegal
and, for that reason, any such individual who pursues such access beyond this
point has implicitly waived and nullified all rights and protections normally
accorded to them by laws, regardless of jurisdiction, and every action
performed or any artifact of such actions which have been created, by such
other individuals may be examined, recorded, copied, used, shared, communicated
or broadcast by whatever channels this individual owner may choose to use,
for any puposes, without suffering any legal repercussions or penalties,
criminal or civil. Furthermore, this system may choose to enact active-defense
measures whose scope, extent and impact would be applied at the discretion of
this system's Owner, again without repercussion for such use or action because
of the self-defense context which triggered the response.
6) This system may not be used as a transit point or gateway for re-transmission
of any information to any other system or communication device, under any
and all circumstances.
7) Unauthorized access will be fully investigated and legal action will be pursued
for damages and compensation amounting to a minimum of
Five Hundred Thousand Canadian Dollars ($ 500,000 CDN),
for the simple act of breach of privacy, for any and all unauthorized access
or use, for any access, data extraction, subversion of the system's normal
operation and security, regardless of the extent of such actions, without
limiting entitlements due to other harms endured, against any individual or
organization which has intentionally circumvented the access control systems,
however strong or meager these may be, without obtaining prior written
authorization from the legal representatives of this individual owner of
this system.
8) Notwithstanding the above, and without jeopardizing this Owner's above-stated
claim of rights and recourse, if any monitoring reveals possible evidence of such
unauthorized activity, which by definition is criminal activity, such activity
will be reported to the appropriate law enforcement agencies and all evidence
gathered will be provided to law enforcement officials for criminal prosecution.
