Since it is "user mode linux", it is mostly just a linux binary. So we should be able to run the executable. Krzysztof: The executable you're running is probably static, which means that you need to brand it so that FreeBSD can know it is a linux binary. not a FreeBSD binary. Try: brandelf -t Linux linux-2.4.19-5 After doing this, it should run, but don't be surprised if it segfaults immediately... There is some problem with it mmapping the sparse file it creates that I never had time to track down. See the thread I started about this a little under one year ago. http://lists.freebsd.org/pipermail/freebsd-emulation/2004-April/000407.html I'm probably going to need uml again soon, so I may try to spend some time figuring this out. Then again, I may just fire up vmware and run uml under vmware like I did before.. Drew
