For some mysterious reason github.com can't be connected to from my network because the IP address that DNS returns is unreachable.

Setting the new resolution rules in /etc/hosts works on the base host:

140.82.112.4 github.com
140.82.113.10 codeload.github.com

But the same doesn't work in the poudriere jail. The same modification in the jail's /etc/hosts didn't take effect.

/etc/resolve.conf files are identical.

I am wondering, are /etc/host files supposed to work in jail?
