Only LD_LIBRARY_PATH, LD_DEBUG and LD_PRELOAD is ignored. From rtld.c: trust = geteuid() == getuid() && getegid() == getgid(); ld_bind_now = getenv("LD_BIND_NOW"); if (trust) { ld_debug = getenv("LD_DEBUG"); ld_library_path = getenv("LD_LIBRARY_PATH"); ld_preload = getenv("LD_PRELOAD"); } So, really just calling setuid(geteuid()) makes things work. No special kludgery is necessary. Ari S. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
