Does it work on cheap Xen vps? Because "/proc/sys/fs/binfmt_misc/register" looks absent from mine.
I think that's because I have WINE installed in the Archlinux VMs, since that's what gets started when I run ./redbean.com. But even after I remove WINE, it still doesn't work, I probably have to restart (i.e. remove WINE from the TemplateVM, not the AppVM) for it to work.
In any case, incredible work, I am in awe!
