Regarding that, and in case it's useful for post-release work: in #59746 I
skipped documenting `resume_offset` with more detail, even if it's needed for
resuming from a swap file.  The reason is that according to [swsusp doc][1],
some specific tool may be needed to compute the swap file offset.  There is
[swap-offset][2] from the uswsusp suite, which is missing from Guix and no
longer shipped with Debian.  I guess that rewriting that small logic in Scheme
wouldn't be too difficult.
