I understand your point. but ptrace(2) based system call interception used by UML makes it depend on the host OS (i.e., linux kernel), while LibOS uses symbol hijacking with weak alias and LD_PRELOAD. we're really thinking to run this library on other POSIX-like hosts (e.g., osx) though it's not coming yet. > BTW: There was already an idea for having UML as regular library. > See: http://user-mode-linux.sourceforge.net/old/projects.html > "UML as a normal userspace library" thanks, it's new information for me. were there any trial on this idea ? -- Hajime -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
