As long as MINSIGSTKSZ is larger than what the kernel actually needs to implement the feature, we are fine. I want to look at how large this is for different OSes that we are "close" with to determine an acceptable value. Surely we need 2K as a high limit for Linux compatibility, but if another OS (say SVR4) has 1K, we need to take that into account. Also, I don't want to drive this value too low -- we can't raise it without breaking backward compatibility. -- Marcel Moolenaar mail: marcel@cup.hp.com / marcel@FreeBSD.org tel: (408) 447-4222 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
