I would like to have the ability to search the article titles only as currently I had to expand every menu item looking for what I want, which I did not find.
i.e.: Jails
I was looking for information on setting up jails on Virtualmin. What are they, the consequences, the benefits, what can I restrict etc…
Instead I just get a lot of results that mean nothing to me as I suspect it is searching the articles for my search term.
Oh, there is no advanced search for the documentation. But, I think the reason you’re not getting the results you want is there isn’t really much documentation about jails.
We use Jailkit. On Debian/Ubuntu, it is the OS-provided package, on EL, it’s our own package of it, which only differs in that it enables capabilities (which makes using chroot safer). The jailkit documentation is what we read when we need to figure out anything related to using and populating jails.
We do something slightly unusual with bind mounts to make home directories work across jailed and unjailed services, but that is mostly invisible to users and administrators, and I doubt you need to know anything about it to use jails as documented.
