can i define my own dnf package groups?

[Robert P. J. Day]

  related to my earlier query (and i'll have a couple more about
package groups and virtualization before i'm done), is there any way
to define my own package groups for personal use, other than manually
hacking the groups.xml file?

  i've scanned the dnf man page, and i don't see any indication that
that's possible -- perhaps a dnf plugin somewhere i haven't found?

I may be misunderstanding your terminology?  There is no concept of a "dnf"
package
group.

package groups are defined within the repodata for each repo.  The file would be
named something like
db434ff174a0a9afa983f7721dda9caaa1d9b6e35517e504e002f824faa87002-comps-Everything.x86_64.xml.gz


I think the groups.xml file you're talking about hacking would be the one found in,
for example, /var/cache/dnf/fedora-cba4cf65782eccda/repodata/gen ?

But that file will be regenerated when the metadata expires.

So, to achieve what I think you want (a new group with your chosen packages) I
believe you probably would want to create a "local" repo with no packages but
with
your custom group definition.

  sorry, just being redundant and superfluous there.

  correct, i was just trying to draw an analogy with what i was trying
to do.

  ah, quite so, i hadn't thought of that, that seems like the easiest
solution.
