where are the repo groups defined

Trying to get a deeper understanding of installation process.  During installation the system is usually installed with pacstrap /mnt base base-devel.  Looking at the repositories, the base & base-devel groups list all of the packages for each of these groups but where are these groups defined?  pacman -Qi attr doesn't list it as a member of the base group even though it obviously is.

Error...my bad.  The attr package isn't part of the base group and performing a pacman -Qi bash does list it in the base group.
So just to confirm this. Does pacstrap query the entire package repo and pull all packages that have "base" as a group membership when you do pacstrap /mnt base?

Re: where are the repo groups defined

The groups aren't defined in a central location. The groups are part of the package description, they are similar to tags.
attr is not a part of the base group, but a dependency of a member of this group. If you want all installed members and the dependencies, then I suggest a command like this:

pacman -Qqg base | xargs -n1 pactree -l  | sort -u

No, it's not. It's a dependency of other packages that are in base, such as coreutils and tar.

These groups are defined by a line like

groups=('base')

in the PKGBUILDs of all the group members. When you build the package, this becomes

group = base

in the .PKGINFO file included in the package (one line per group).

Re: where are the repo groups defined

~ % pacman -Qi attr
Name           : attr
....
Groups         : None
....
Required By    : acl  coreutils  lib32-attr  libarchive  libcap  patch  tar
...
Install Reason : Installed as a dependency for another package
....

I think it pretty much explains how it was installed along with base group.
