It seems that the only way to set the output of uname in
a jail is to define environment variables.
Unfortunately, there doesn't seem to be a reliable way
to unconditionally set them (a process might do the
equivalent of 'env -i /bin/sh' and unset them, etc).
Apart from just patching the uname utility before I
copy it into a jail, is there really a good way to do
this?
I would love to just be able to set a sysctl and have
this work.
$ jls | grep i386
