linux_base-f10-10_7 installation failure on FreeBSD 10.1 BETA2

[Rostislav Krasny]

Hi,

I've FreeBSD 10.1 BETA2. I tried to install a package of nVidia 304.xx
driver. This package depends on the linux_base-f10 one. The
linuxulator installation has failed. See the "sysctl: unknown oid
'compat.linux.osrelease': No such file or directory" line in the
following installation log.

Is it a known problem?

root at saturn:~ # pkg install nvidia-driver-304-304.88_2
