The spell Glyph of Warding allows one to charge the glyph with a spell that is cast when the glyph is triggered:
Spell Glyph. You can store a prepared spell of 3rd level or lower in the glyph by casting it as part of creating the glyph. The spell must target a single creature or an area. The spell being stored has no immediate effect when cast in this way. When the glyph is triggered, the stored spell is cast. If the spell has a target, it targets the creature that triggered the glyph. If the spell affects an area, the area is centered on that creature. If the spell summons hostile creatures or creates harmful objects or traps, they appear as close as possible to the intruder and attack it. If the spell requires concentration, it lasts until the end of its full duration.
The spell Gentle Repose preserves a corpse from being raised by the dead and extends the amount of time spells like Raise Dead and Revivify have to operate on it. However, the material requirements of the spell are:
a pinch of salt and one copper piece placed on each of the corpse's eyes, which must remain there for the duration
Further, this answer suggests that placing the coins is not an optional step in casting the spell.
In theory, the Glyph of Warding spell would seem to allow a Cleric to place the Gentle Repose spell in the glyph, with the trigger that it activate when someone nearby dies. However, given that when the glyph activates there may not be anyone present to place the coins on the corpse's eyes, is this spell (and any spell that requires the caster to perform some additional action) essentially incompatible with Glyph of Warding?
