>Organization:

>Environment:
System: FreeBSD nkz.delikates-nk.ru 6.1-RELEASE FreeBSD 6.1-RELEASE #0: Sun May 7 04:42:56 UTC 2006 root at opus.cse.buffalo.edu:/usr/obj/usr/src/sys/SMP i386

>Description:
	I've booted 6.1-RELEASE installation CD and installed this release
	using 'Custom' mode. I've created 128M-sized root and 256M-sized /usr,
	4G /usr/local and 15G /home and selected only base distribution
	(and kernels).

	I've booted the new installation from hard drive, created directory
	/home/ports and made symlink /usr/ports -> /home/ports.
	Then I mounted CD and ran sysinstall to install Ports Collection.
	I hoped it will populate /home/ports. However, sysinstall removed
	/usr/ports symlink and started to fill /usr/ports directory,
	quickly ran out of vnodes and failed.

	The same attempt for src distribution was successful, sysinstall
	has not removed /usr/src -> /home/src symlink and populated /home/src
	directory.

>How-To-Repeat:
	
	Make empty /home/ports directory, make /usr/ports symlink pointing
	to /home/ports, run sysinstall and try to install Ports Collection
	from FreeBSD 6.1-RELEASE CD (disk1). Sysinstall removes /usr/ports
	symlink, recreates it as directory and unrolls ports to /usr partition.

>Fix:

	Unknown.
