The script is in the final stages. Ideally, there are more collaborators with shell script knowledge and connectivity at FW Merlin to give an opinion. I want to contribute, but my knowledge is focused on infrastructure and connectivity. I think it contributes enough to the RMerlin project.
 
new script also dosent fix adblock
run unbound_installer.
Choose option 1. Update the installation. Edit /opt/var/lib/unbound/unbound.conf and uncomment the adblock path. Run /opt/etc/init.d/rc.unslung restart. Let's fix the script.

The adblock feature has worked since v1.07, as your original 'unbound.conf' appeared to use the convention
Code:
# include:......adblock/adservers
where there is a single space between the '#' and the 'include:' directive, however your new 'unbound.conf' now omits the space char
Code:
#include:...….adblock/adservers
and now no version of the script can match '# '

I have patched the script ready for v.1.11 (not yet pushed to GitHub) to accept either style, but in the meantime you should fix 'unbound.conf' hosted on your GitHub to reinstate the space char.

This thread and script when in a different direction than I anticipated or feel I could contribute to. I use unbound only as an upstream resolver for dnsmasq, relying on Diversion for adblocking and using no DoT whatsoever.

I want the hook between dnsmasq and Unbound to be failsafe, meaning if unbound isn't running, dnsmasq reverts to the normal WAN DNS servers. I do this through the dnsmasq.postconf script I've posted before in this thread. I also created a cron job to check unbound every 5 minutes and if it isn't running, restart dnsmasq so that the WAN DNS servers will take over, to minimize chances of a DNS-related outage in my home.

I don't understand where some of these requirements are coming from to use Entware Stubby, or use another adblock solution, or to try to force all requests to Unbound. To integrate with the firmware, it needs to have clean edges and integration points IMHO.

To gain widespread adoption, this script should do one thing very well: install Unbound as a recursive, validating resolver. All the extras might distract from other users understanding what it is doing and wanting to install it.

@Martineau will be canonized once his work here is done, or he walks away, whichever comes first. ;)

I understand your concern. But I assure you, it works the way it should. And query requests are being made by untying normally. I understand that comments like yours strengthens the post. I really appreciate it.

@Martineau The dnsmasq.postconf file is generated in incorrect formatting and without write permission.

Maybe it’s time to do like Diversion and just add a single line to dnsmasq.postconf that invokes a specific script created by the installer to contain all the dnsmasq changes, instead of guessing what might or might not already be present.
Code:
. /jffs/scripts/unbound.postconf “$1”
 
@dave14305 Coexistence with dnsmasq-oriented solutions is perfectly possible. Diversion, No-Track, Pi-Hole (great software) coexist perfectly with the coupling. I speak daily in the forums of these projects. But specifically targeted solutions for unbound are preferable. Forums like PFsense and OPNsense greatly strengthen this reasoning.

Of course it is possible. My suggestion is that if you want to minimize the problems integrating with existing dnsmasq.postconf files, then consider calling the unbound specific script from dnsmasq.postconf as a one-liner and ensure that line comes after any other modifications to /etc/dnsmasq.conf.

I will wait to discuss with St. @Martineau.

Of course I agree with you. This is a great solution for dnsmasq-integrated software compatibility such as Diversion.
 
Trying to configure Munin here for Unbound

@Martineau script generated without write permission and with incorrect adblock cron argument.
/jffs/scripts/services-start
Code:
cru a adblock "0 5 * * *" /opt/var/lib/unbound/adblock/gen_adblock.sh                   # unbound
Manually fixed
chmod +x /jffs/scripts/services-start
Code:
cru a adblock "0 5 * * * /opt/var/lib/unbound/adblock/gen_adblock.sh"                    # unbound
 
I tried this
Changed Cru to new code but adblock still dosent work

Unbound Installer v1.11 uploaded

1. Fix Adblock ENABLE (i.e. uncomment '# include:' ) in 'unbound.conf' even if '#include:' format is used by @rgnldo
2. Fix 'services-start' Adblock 'cron' job syntax
3. Fix (Hack??? i.e. issue existing command TWICE!!! o_O) 'chmod +x' to 'services-start'/'dnsmasq.postconf' if they are created
4. Fix 'dnsmasq.postconf' order of statements if it is created
5. Download files '/opt/etc/init.d/S61unbound' and '/opt/etc/init.d/S02haveged' from @rgnldo GitHub
6. Add menu option 'v = View ('/opt/var/lib/unbound/') unbound Configuration (vx=Edit)'
