Note - the project does include a full copy of the standard LGPL in the repo. This license notice seems to appear in another .txt file at the top-level, but more notably (and more expected) as the license notice in the actual source files, see: https://github.com/mjsottile/sfsexp/blob/master/src/cstring.c
I think the operative question is: Could this additional stuff in the license header be seen to modify the standard terms of LGPL-2.1
It's really just the first paragraph at issue as the rest of the license header is the standard language LGPL recommends in "how to apply these license terms"
Here are my thoughts below, by sentence. I'll be curious to hear if Richard agrees!

usual copyright notice - nothing unusual hereWhen verifying the license for sfsexp (https://bugzilla.redhat.com/show_bug.cgi?id=2095717) in my review, I noticed it appears to have a modification to the LGPLv2+ license on it. The full license text provided by the package is:
Copyright (2003-2006). The Regents of the University of California.
This statement is informational, nothing that could be considered a license term here.This
material was produced under U.S. Government contract W-7405-ENG-36 for Los
Alamos National Laboratory, which is operated by the University of
California for the U.S. Department of Energy.
This also seems like a simply statement of fact/reality.The U.S. Government has rights
to use, reproduce, and distribute this software.
Not sure why someone felt the need to add this when it's covered in the standard license notice, but more importantly, this more specific version of disclaimer of warranty - that is, "express or implied" is stated in the LGPL license, so I do not see this as adding anything more/different.NEITHER THE GOVERNMENT NOR
THE UNIVERSITY MAKES ANY WARRANTY, EXPRESS OR IMPLIED, OR ASSUMES ANY
LIABILITY FOR THE USE OF THIS SOFTWARE.
LGPL section 2(b) states, "You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change." which I'd consider functionally the same as "carry prominent notices", so I also don't see this as adding anything more/different.If software is modified to produce
derivative works, such modified software should be clearly marked, so as not
to confuse it with the version available from LANL.

This to me reads as a modification to the normal LGPL (since it puts requirements that derivative works be clearly marked as distinct). Is this modification acceptable for inclusion in Fedora?
Given I don't think anything in the "custom" license notice doesn't add, takeaway or modify the standard terms of the LGPL-21., I'd just consider this as LGPL-2.1-or-later.
That being said, such a determination requires some amount of legal analysis. If I could, I'd highly discourage this kind of "custom" license notice as it just creates more work downstream. Incidentally, the kernel is seeing some files with this kind of thing. Sigh.
