FreeBSD

Hi List Members!
I'm proud to announce the first update to my host-setup utility (a
dialog(1)-based host configurator for FreeBSD). The following changes have been
made:
- fixed bug where /etc/resolv.conf would be created with 0600 permissions
- fixed bug when switching from one default gateway to NO default gateway
- fixed typo in the title of netmask prompt and ifconfig options dialog
- fixed bug that prevented entry of netmask if no netmask is configured
You can get the updated version here:
http://druidbsd.sourceforge.net/download/host-setup.txt
or
http://druidbsd.sourceforge.net/download/host-setup.gz
or
http://druidbsd.sourceforge.net/
For those not familiar with my host-setup(1) utility, it is a 2,500+ line shell
script that utilizes the dialog(1) utility to walk the system administrator
through setting up their TimeZone, Hostname, Network Interfaces, Default
Gateway, and DNS. Our custom FreeBSD installer sets this script as the root
login shell, making it very easy for field engineers to quickly get a system on
the network without having to use the command-line (and without having to reboot
either). Underneath the hood - behind the system of prompts and dialogs - this
script manages both the contents of /etc/rc.conf, /etc/resolv.conf, and others
as well as utilizing ifconfig(8), route(8), and many other tools to avoid
requiring a reboot, prompting you if you would like to make the new changes
effective when values are changed from their active settings.
Here's the patch to show the details:
