bedrock, makewhatis question

I'm running bedrock with Void as the init stratum. Had an error message while running makewhatis:
# makewhatis
/bedrock/cross/man//mandoc.db: Data changed, but cannot replace database
# brl which makewhatis
# strat -r void makewhatis
I was then able to run apropos and see things I had not before, so success.

In normal bedrock functioning, should it be necessary to perform a restricted run of the init stratum's version of makewhatis?

makewhatis -np >/dev/null
output anything?

Do you have $MANPATH defined? What are the contents of /etc/man.conf? Does the latter file exist in the void stratum only or in the bedrock stratum as well? If yes, are they identical? Or, perhaps, man.conf should be listed in /bedrock/etc/bedrock.conf under [global]/etc?

The Bedrock Configuration page says
To ensure unwrapped calls are run through /bedrock/cross, configure them as pin entries under [cross-bin] as well.
So, perhaps adding
pin/bin/makewhatis = init:/usr/sbin/makewhatis
to /bedrock/etc/bedrock.conf will help?

As to the error message, the source of mandoc has the following comment
 * We lack write permission and cannot replace the database
 * file, but let's at least check whether the data changed.
BTW, the Void Handbook says
The mdocml package provides a cron job to update the database daily, /etc/cron.daily/makewhatis. You will need to install and enable a cron daemon for this functionality to be activated.
Does it work when running a Void stratum on Bedrock?

Hmm, it's interesting that Void uses mandoc by default. I'm used to think of it as of a mostly *BSD thing.

As to your question, I'm not using Bedrock, so cannot help. I can only say that using mandoc by default (and makewhatis which is its part) is a peculiar Void feature. Most other Linux distros use man-db instead. Don't know how Bedrock handles this. At least, the Bedrock Distro Compatibility page lists Void as all green.

Anyway, the Bedrock Basic Usage page says
In general, if something acts oddly under Bedrock, the first thing you should try is to restrict it.
Which seems logical when dealing with a Frankendistro that Bedrock is.

Props to shruggy's thorough answer. My guess is the final bit of advice is what's needed here - `makewhatis` should probably be run restricted to avoid that error message.

Thumbs up encountered same, but got stumped by own silly

Thanks for this thread. This thread/question was helpful. Solved my similar issue, when attempting man emerge.

"man: outdated mandoc.db lacks emerge(1) entry, run makewhatis /bedrock/cross/man".

Ran with sudo or su: "/bedrock/cross/man//mandoc.db: Data changed, but cannot replace database".

"man emerge" showed messy jibberish characters, "strat -r jentoo man emerge" showed correctly.

Couldnt "strat -r jentoo makewhatis" (no makewhatis in that stratum), which (besides brl repair) was my first and last thought what to do, before websearch got me here. (Edit: Which I see, in hindsight, the unthinking conceptual presumption mistake of logic I made. If "strat -r jentoo man emerge" worked, rebuilding the db in jentoo stratum wouldnt be the issue.)

It being a gentoo man page I sought, I'd have not thought to "brl which makewhatis" (Edit: and do the resulting "strat -r void makewhatis"), which is what stumped me for a while.

I don't know if that's just my system unfamiliariarity and lack of wits, or, if that (different strata's man, init stratum's(/void's) makewhatis) might be a helpful additional little point to make here for others too (Edit: and/or for my future forgetful self). Posting this reply incase the latter.

"strat -r void makewhatis" solved for me, what, without this thread, would have been its own question thread. thanks.
