	# As of version 3.5.3 this seems to be very much broken, affecting
	# commands which have got nothing to do with singularity (example:
	# completion on 'udisks mount -b /dev/' rejects all files from that
	# directory other than 'autofs'). Moreover, this should go into
	# $(get_bashcompdir) (from bash-completion-r1.eclass) rather than /etc.
	# Hopefully temporary, which is why we delete this at install time
	# instead of patching build scripts not to generate bash-completion
	# data in the first place.
