quick fix about 'failed to seed the random number generator' problem:
edit /etc/init.d/dnsmasq
add /dev/urandom at the end of this line procd_add_jail_mount /etc/passwd /etc/group /etc/TZ /etc/hosts /etc/ethers
final line looks like:
procd_add_jail_mount /etc/passwd /etc/group /etc/TZ /etc/hosts /etc/ethers /dev/urandom
