linux emulation questions

[r0ller <r0ller%freemail.hu@localhost>]

Hi All,

I wanted to check if a linux program runs "better" if only linux specific code is invoked as it seems in certain cases the linux binaries find netbsd ones and execute them which leads to uncertain results. For example when a linux gradle install calls 'uname' and gets 'NetBSD' which results in 'unsupported platform'. So I created a PATH including only linux emulation specific directories like:

export PATH=/usr/pkg/emul/linux/bin:/usr/pkg/emul/linux/sbin:/usr/pkg/emul/usr/bin:/usr/pkg/emul/linux/usr/sbin

But when starting the linux executable (Android Studio by the way), I get:

./studio.sh: which: not found

Isn't 'which' part of the suse_base? Actually, all the suse_*-13.1* packages are installed and 'find' does not find 'which' anywhere under /usr/pkg/emul/linux.

Another question is if it's possible to set up (similarly to PATH) that only linux libraries are searched for? I know that LD_LIBRARY_PATH can be set to list the linux lib dirs but that's checked last if I'm not mistaken.

The last question is just a kind of security one: is it possible to tell the system that only a certain process and its children are enabled to emulate linux? I mean e.g. like a terminal could be launched with the linux emulation enabled option and whatever gets started there inherits that option.

Best regards,
