After FBSD-9.3 BSDINSTALL has installed a new system, there is a symbolic link of "/compat -> usr/compat". Unfortunatly, BSDINSTALL fails to create "/usr/compat" which then prevents any (compat) Linux installations from succeeding.
Resolution: manually create required directory, "mkdir /usr/compat".
bsdinstall doesn't create any directories, it just extract the distfiles. If this direction should be created, it should be included in base.txz
I have not had the compat linux installs fail on any of my systems, do you have the error messages you get when trying to install a compat linux package?
I remedied the situation and completed a FBSD-9.3 installation.
If I remember correctly, I deleted the "/usr/compat" directory.
