Bug 23493

Summary: race in 'make -jN buildkernel' pollutes /usr/src
Product: Base System Reporter: richards+bsd <richards+bsd>
Component: kernAssignee: freebsd-bugs (Nobody) <bugs>

Description richards+bsd 2000-12-12 05:50:00 UTC 
	When building a kernel with 'make -jN buildkernel', the links
	'@' and 'machine' are created in both /usr/obj/.../modules/*
	and certain subdirectories of /usr/src/sys/modules.  How many
	of the latter depends on N.  On my machine, N = 5 pollutes
	only accf_data; increasing values of N pollute a greater
	number of directories (in the order they appear in the
	definition of SUBDIR).

Fix: 

Unknown.
How-To-Repeat: 
	# cd /usr/src
	# chflags schg sys/modules/accf_data
	# make -j5 buildkernel

Does this problem still exist?
