Here is 0000usepeerdns-up:
#!/bin/sh -e
# this variable is only set if the usepeerdns pppd option is being used
[ "$USEPEERDNS" ] || exit 0
# exit if the resolvconf package is installed
[ -x /sbin/resolvconf ] && exit 0
# create the file if it does not exist
if ! [ -e /etc/resolv.conf ]; then
: > /etc/resolv.conf
fi
# follow any symlink to find the real file
REALRESOLVCONF=$(readlink --canonicalize /etc/resolv.conf)
# merge the new nameservers with the other options from the old configuration
{
cat /etc/ppp/resolv.conf
grep --invert-match '^nameserver[[:space:]]' "$REALRESOLVCONF" || true
} > "$REALRESOLVCONF.tmp"
# backup the old configuration and install the new one
cp -a "$REALRESOLVCONF" "$REALRESOLVCONF.pppd-backup"
mv -f "$REALRESOLVCONF.tmp" "$REALRESOLVCONF"
# tell nscd that the file has changed
[ -x /usr/sbin/nscd ] && /usr/sbin/nscd -i hosts || true
exit 0
And 0000usepeerdns-down:
#!/bin/sh -e
# exit if the resolvconf package is installed
[ -x /sbin/resolvconf ] && exit 0
# follow any symlink to find the real file
if [ -e /etc/resolv.conf ]; then
REALRESOLVCONF=$(readlink --canonicalize /etc/resolv.conf)
else
REALRESOLVCONF=/etc/resolv.conf
fi
# if an old resolv.conf file exists, restore it
if [ -e $REALRESOLVCONF.pppd-backup ]; then
mv -f $REALRESOLVCONF.pppd-backup $REALRESOLVCONF
# tell nscd that the file has changed
[ -x /usr/sbin/nscd ] && /usr/sbin/nscd -i hosts || true
fi
exit 0
