LilyPond - Grace note too close to the barline

Question

Lilypond places the grace notes very close to the barline (see image). Is it possible to create more room between the barline and the notes?

Answer 1

How about

{
  \key ces \major
  \bar ".|:"
  \grace \tweak extra-spacing-width #'(-1 . 0) as'8 \glissando
  ces''2
}

or

{
  \key ces \major
  \temporary\override Staff.BarLine.space-alist.first-note = #'(fixed-space . 6)
  \bar ".|:"
  \grace as'8 \glissando
  \revert Staff.BarLine.space-alist.first-note
  ces''2
}
