Re: why does linux-base-f7 exist if the binary compatibility is to a kernel too old to run it? (and how to change that?)

possible if the kernel is too old for it?


no idea about /usr/port/emulators/linux_base-8 which that article talks
about, its not in my ports tree. but you can use linux_base-f7 if you
set compat.linux.osrelease=2.6.16

Sorry to answer myself here, but Just looked and it seems
/usr/port/emulators/linux_base-8 was the redhat 8 port (ie ancient) and
has been
removed.(http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/linux_base-8/Attic/Makefile)

however its still a work in progress and wont always work as intended,
for example it works fine on my laptop
{root@prawn}#pkg_info -Ix linux_base
linux_base-f7-7 Base set of packages needed in Linux mode (for
i386/amd64)
{root@prawn}#sysctl compat.linux.osrelease
compat.linux.osrelease: 2.6.16

and I can use acrobat and other linux binaries, however my desktop at
home would not start acrobat reader using compat.linux.osrelease=2.6.16
and linux_base-f7-7, and I had to go back to linux_base-fc-4_10 and
compat.linux.osrelease: 2.4.2.

Stop in /usr/ports/emulators/linux_base-f7.

Theres work in progress to update the binary compatibility.
http://wiki.freebsd.org/linux-kernel

I would imagine the linux_base-f7 is useful for testing.
