Hi Linux emulation experts,

I installed 'linux_base-c7' on freeBSD12, and its glibc version is '2.17', =
but I have a linux application, it is depended on glibc-2.27.
So I upgrade the glibc in /compat/linux to '2.27', (I just copy glibc 2.27 =
from Ubuntu 18.04 to 'compat/linux/lib64':
ld-2.27.so
libc-2.27.so
libdl-2.27.so
librt-2.27.so

Then I run my application, it is reported the error:
FATAL: kernel too old.

Then I run a simple help world (only print a message), it can work before m=
y glibc upgrading, but now get the same error.

Anything I missed?
