trying to clarify a couple things regarding installing/removing
by yum group on my fedora 19 system. first, what is the rationale
behind "hidden" groups? what's the motivation that some groups
(for the case i'm interested in, virtualization) not be user visible?
The main idea with hidden is for things like "base", where it's
assumed the user doesn't need to see it. But even that might not be
true now we have groups as objects.
not sure what it means to say "groups are objects" (still reading
Basically if group_command=objects (default in F19+), instead of
group_command=simple or compat (compat is the default in all older
versions).
With groups as objects then "yum group install foo" has an object
representing "foo" and marks that as installed (and which packages are
installed as part of it) ... without it yum works it out on the fly
based on which packages are installed (Eg. if all the mandatory
packages for a group are installed, then that group is installed and
all the packages "belong" to it).
or you could have just linked me here: :-)
http://fedoraproject.org/wiki/Features/YumGroupsAsObjects
one last potentially dumb question (well, not really, more coming)
is -- how does one list which "groups" are currently "installed"?
as i read it, if i install the "virtualization" group, something
is now recording that that "object" (the virt group) is installed.
say i now remove one of its mandatory packages explicitly. is that
group now considered to be installed? and how could i display that?
i suspect i just need to spend a few hours reading man pages, and
fedora wiki pages, and testing.
