Well, its somewhat interesting because it runs entirely in userland
and traps system calls via a SEGV handler. And because of this, I
imagine that its a good bit slower. Also, their '$LINUX_ROOT' path
remapping is interesting if only for its flexibility, but their choice
of what paths to remap is very haphazard compared with the {Free,Net}BSD
approach.
BTW -- should anybody care, I just ported it to Solaris/x86 (which I'm
forced to deal with at work). I'd be happy to give out the diffs.
It runs Adobe Acrobat just fine (well, after installing the FreeBSD
linux-libs pkg ;-)
Cheers,
Drew
