Description

If the firewall has a DHCP WAN, and the DHCP server on WAN supplies a hostname to the client, the firewall will take the hostname given and clobber the hostname configured from System > General.

Removing or commenting out the call to check_hostname in /sbin/dhclient-script allows the firewall to retain its chosen hostname. It isn't clear if this behavior is actually desirable or if that code is safe to remove, hence the ticket.

The logic change from commit:e912bfae186b6b657daf52607f9d027f46be0478 (2.1.x) and commit:ff3da5dba67c64514808e86165e92362f3ff8b33 (2.2) seems to have triggered this new behavior. This affects 2.1.4 and 2.2.
