Hi there!

I wanted to ask if a VPS does support binfmt if the host-kernel is
compiled with the binfmt-module??

Thanks!

AFAIR it can be used, but it is not virtualized,
so it is insecure :/

Hmm I don't think it can be used out of the box... I've loaded the
binfmt_misc module and enabled some wrappers for php for example on the
host-system. However within the vps system I'm unable to set the
"update-binfmts --enable"... this always tries to load the module which
ofcourse isn't available. lsmod in the vps doesn't show any module
(maybe that's the problem??).

Quite natural since binfmt_misc is not virtualized as Kirill already
said, meaning that filetype -> interpreter mappings

- are global (work in all VEs where the corresponding interpreter is
found under the specified path)
- can only be manipulated in the host system.
