You may have found many great resources on how to set up jails on latest FreeBSD, however there is scant information on how to go about creating a barebones jail with nothing but the one process that you want to isolate.
I was curious if I could contain a statically compiled web server that I wrote while learning Rust all by itself in a jail instead of having a full userland.
Ubuntu, Fedora, openSUSE, CentOS, SUSE Linux Enterprise, Debian,... users can finally use Autodesk Fusion 360 in the Linux Browser now.
On Chromium 55.0.2843.0 I get NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED.

Before installing this JRE, you have to install the linux binary compatibility on FreeBSD, you can follow this documentation. Jave requires some information about the proc. You have to mount linprocfs, type:
kldload linprocfs
mount -t linprocfs linprocfs /compat/linux/proc
and add this line to /etc/fstab:
linprocfs /compat/linux/proc linprocfs rw 0 0

| list *l = (list *) malloc(sizeof(list)); | |
| l->count = 0; |
Determine the file system by using the file-utility.
file image.imgUse mdconfig to link the IMG image to a virtual device.
mdconfig -a -t vnode -f /path/to/image.img -u 0
What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.
In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.
Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th
