PKGBUILD and sysctl
Greetings,
I am currently working on an AUR package, and after the package is installed correctly, I need to execute sysctl to modify a setting on the system.
My first question is, is this even a good idea? Or ask the user with an echo to run the sysctl command themselves?
If it is cool with AUR, what would be the approved method to drop a file in /etc/sysctl.d/99-namehere.conf and activate it after the package is installed?
Thanks in advance

No to the first, yes to the second as a reasonable option, but ...

You don't. You install it to /usr/lib/sysctl.d/ and use a post install message to instruct the user to copy/link that to /etc/sysctl.d/.
EDIT: perhaps not. I suspected /usr/lib/sysctl.d was a staging place for bits that could be 'activated' by placing them in /etc/, but it seems they are read too. So my suggestion would be to just echo a message telling a user to create such a file. Though this may depend to a degree on exactly what the setting is. If the setting is absolutely essential for your packaged software to work at all and it will not have *any* other side effects, then perhaps you could just package the file for the setting.

Re: PKGBUILD and sysctl
Note also, that the systemd package provides a pacman hook /usr/share/libalpm/hooks/systemd-sysctl.hook
So sysctl settings will be automatically updated, by default.
Note that I make no claims to the advisability (or not) of setting any sysctl in the first place. I merely point out that if you do use one, there's no need to do anything or message the user in the post-install, in order to apply it.
