Yes, it will be evaluated each time rc.conf is sourced by some startup script, and it might cause a lot of expr invocations, but it seems to set all the relevant environment vars for me.. G'luck, Peter -- I am not the subject of this sentence. iface=rl0 eval `( i=0 exec < iplist while read ipads; do echo "ifconfig_${iface}_alias${i}='inet $ipads netmask 255.255.255.255'"; i=$(expr $i + 1); done )` To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
