A list of those would be useful unless access to your system is available?

If they start with 0p_... or zp_... they are perpetual pre- or post- postinstall 
scripts e.g. all systems should have the following:

	0p_000_autorebase.dash
	0p_update-info-dir.dash

	zp_man-db-update-index.dash

run after all other setup steps have been performed, but either before or after 
all postinstall scripts in installed or upgraded packages have been run.

See "setup.exe new postinstall facitilities":
