Perhaps have the code which exterminates such a process if it goes wrong be a little more forthcoming with why, if having a useful error message would help. > > In the short term, this will have the happy side effect that static > > Linux ELF binaries will suddenly magically work, which is a Good Thing. > > IF, the linux emu is loaded, and libs are installed, and you are > lucky to have the right versions of them :( Ok, "modulo the usual Linux crap". Note that the path-detecting code probably wants to understand /compat/netbsd, which hadn't occurred to me before. NetBSD people lurking - is there a reliable way to discriminate a static NetBSD ELF i386 binary from any other static i386 ELF binary? > > > markelf, brandelf or just plan elf (fixelf sounds a bit harsh :) ) > > > > Heh.

I sprayed my breakfast all over my desk when I read "elfspay" 8) I can just see the example now : "elfspay -t <ypetay> ogrampay" > Soren Schmidt (sos@FreeBSD.org) FreeBSD Core Team -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
