I just did "emerge -pv --update --deep --with-bdeps=y @world". Of the 33 packages that would be installed/updated/etc, one (only 1) is a new package, "virtual/service-manager-0".

I've searched the internet and don't really see any information on what this package does. I did "equery depends service-manager" and the report was that nothing depends on service-manager.

So what is service-manager and why is it needed now when it wasn't needed the last time I updated, which was maybe a month ago?

Thanks in advance for any insight,
ElleStone

ElleStone,

Anything called virtual/* does not actually install anything.

Packages that have dependencies that can be satisfied by one of several alternatives usually depend on on a virtual/*
If nothing that satisfies the virtual is installed then the first named package in the virtual will be installed.

In your case, the key text from the ebuild is

Code:
 RDEPEND="
        prefix? ( >=sys-apps/baselayout-prefix-2.2 )
        !prefix? (
                || (
                sys-apps/openrc
                kernel_linux? ( || (
                        sys-apps/systemd
                        sys-process/runit
                        virtual/daemontools
        ) ) ) )"

So, you either need sys-apps/openrc, or you need kernel_linux or one of the other things there.

It looks like this virtual has been added to help make init systems other than sys-apps/openrc easier to support

Hi NeddySeagoon,

I've been installing the 33 updates in chunks, trying to see what was pulling in the virtual/service-manager-0, then rereading your message to see if it started to make sense.

Finally I got it, I think. None of the 33 updated packages need virtual/service-manager-0. I already have sys-apps/openrc installed. This new virtual package isn't going to pull in any new packages. It's is probably being installed on everyone's Gentoo system? A sort of future-proofing for things to come?

ElleStone,

Thats a reasonable summing up.
