I don't disagree that it is a gotcha, which is why I mentioned
it.  (And I've mentioned it before.)  I disagree that it should
simply be changed to a defvar.  (But I don't feel strongly about

Please read the doc string of option `custom-file' carefully.
IMO, users should be able to take advantage of Customize when
defining the value.

What's missing is up-front mention of this in the manual,
at the place where we explain the init file (node Init File).

The general _recommendation_ should be to use `custom-file',
and in node `Init File' we should present a simple init-file
example that shows how to do this.  That's all.

The newbie question "Where is my init file?" or "How do I
create my init file?" gets asked over and over anyway, even
though this is covered in node `Init File'.  The same way the
node answers that question, it should show users how to set
and load `custom-file' in their init files.  End of story.

Another thing that could help is for Customize to remind
(nag) you whenever you try to save anything, if `custom-file'
is nil.  The nag should point you to the doc about
`custom-file' in node `Init File'.

An option could turn off this nagging, or a particular
response when nagged could turn it off.  IOW, the nagging
would be for the benefit of newbies, not those who are
aware of `custom-file' but prefer, for whatever reason,
not to use it.
