Hi!

No, I think you are right.  This is indeed a glissando, IMO.
But as LilyPond understands it a glissando needs a starting note and
a note to end.
You have the ending note but no visible starting one, hence the trick.

What about

\relative c'' {
  \key g \major
  \time 4/4
  g1 \breathe |
  \grace { \hideNotes a,8\glissando \unHideNotes } a'8 a4 a8 a2~ |
  a1 \bar "|."
}

If the first (hidden) note is too close the second one (real,
unhidden note), then we do not see the glissando.

James' idea is great too, maybe you could play on the fraction (and/or
on the first hidden note).
The sum of hidden note duration and real note (end of the glissando)
duration should be equal to 8*1.
For example : 1/8 and 7/8, like this:

\relative c'' {
  \key g \major
  \time 4/4
  g1 \breathe |
  \hideNotes a,8*1/8\noBeam\glissando \unHideNotes a'8*7/8 a4 a8 a2~ |
  a1 \bar "|."
}


The same idea has been used successfully in this thread:
"glissando up from no note to a note"

Hope this could help.

Cheers,
Xavier
