[gentoo-portage-dev] glsa implemented as a special set

[Brian]

I had an idea this morning about implementing glsa as a special set.  I
know the current portage code base is not ready for /etc/portage/sets
support, but I thought it might be an easy way to integrate a glsa
up/downgrades group (set) listing in portholes upgrades view (needs some
familiarity of porthole's gui).

I was thinking that /etc/portage/sets/glsa could be a symlink to set
list in the current metadata/glsa directory of the portage tree.  That
file should be relatively easy to auto-generate from the existing
glsa*.xml files there already.  Perhaps a FEATURES="GLSA_SET" would
generate that file on completion of an "emerge --sync"  I could also
then put a GLSA field into porthole's package Summary view as well as a
GLSA notebook page(s) to display the appropriate glsa?.xml file(s).

What do you think of the idea?   Then as portage/pkgcore gets sets
support all anyone would need do is:

# emerge -upv glsa
(or any proper way emerge will handle set names)

for a cli listing of packages needing attention.  The one thing I can
think of that would need slightly different handling from normal set
parsing would be to only list those qualifying packages that are
installed and ignore any other not installed package listed.
