Run different Linux jails at the same time

[probonopd]

The README says

You can't run different Linux jails at the same time.

Why is this?

Couldn't one set up a different compat.linux.emul_path for each, and run them in parallel?

My objective would be to make a standalone directory (simplified .app bundle actually) that contains the compat.linux.emul_path and everything needed to run the browser.

if this can be properly jailed then why not

There is only one instance of the linuxulator running in the kernel, and you can set only one emul_path path. If you put the Linux environment into a FreeBSD jail, there might be some path translations involved that could allow more than one Linux environments to run at the same time. But this is just speculation. I know too little about the details of FreeBSD jails.

Just to clarify: emul_path isn't really used with Linux jails/chroots. It is used when trying to run Linux applications outside of jails/chroots.

[probonopd]

Looking at the code, /usr/local/bin/linux-chrome is currently executing ${jail_path}/bin/chrome directly, no chroot nor jail used. (The variable name is misleading.)

So it would be great if we could export EMUL_PATH=... to override any system-wide emul_path, effectively giving us a way to separate different Linux environments from each other without needing root rights.
