Oh, hmm. Then I think it won't work, will it? I'd assumed fexecve was implemented in kernel. > Cute, and I can do that. Assuming /proc is mounted in the chroot > environment... Maybe I'm just confused -- wouldn't be the first time -- but if it's implemented inside userspace, then once you chroot() you won't be able to execute the path you find via /proc, will you? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
