FreeBSD 9.0-RELEASE AMD64 sysinstall installation issues

[CeDeROM]

Hello :-)

There are some problems with FreeBSD 9.0-RELEASE AMD64 dvd1.iso
installer when using SYSINSTALL (shell -> sysinstall). A directory
"/dist" seems to be missing on the cd9660 filesystem and so packages
cannot be mounted/extracted into that location, making installation
impossible. The errors after COMMIT are following:

"Couldn't create directory /dist: Read-only filesyetem" , "Error
mounting /dev/cd1 on /dist: No such file or directory (2)".

Please advise.

Best regards,
Tomek Cedro
