Thanks to Sean of The Boston Diaries [0], who sent me an email about
his Gemini  server GLV-1.12556  [1], with  a link  to the  page that
lists the other known Gemini servers. After some research, I decided
to install  Solderpunk's Molly-Brown  [2], which  was a  fairly easy
setup as Go along with the required libraries were already installed
on the Republic. So Gemini hosting is now live there [3].

For anyone  who needs a FreeBSD  rc script for their  Gemini server,
here is the  simple one I am using. It  goes in /usr/local/etc/rc.d,
and  supports the  standard rc  script arguments  like stop,  start,
restart and status. Note I'm  running the server as the unprivileged
user 'gem'.

cat > /usr/local/etc/rc.d/molly <<'EOF'
#!/bin/sh

#

# PROVIDE: molly
# AFTER: NETWORKING
# KEYWORD: molly

# Add the following lines to /etc/rc.conf to enable `molly':
#
# molly_enable="YES"
#
. /etc/rc.subr

name="molly"
rcvar=molly_enable

command="/usr/sbin/daemon"
command_args="-S -p /var/run/molly.pid -t molly -u gem -T molly /usr/local/bin/molly"

load_rc_config ${name}
: ${molly_enable="NO"}

run_rc_command "$1"
