33 I definitely agree. That's what the blurb about "Temporary GLSA" is
34 about in the Vulnerability Treatment Policy :

38 If we can define this tiers and everyone agree on them, that's fine.

40 IMHO we need at least one GRSEC-hardened kernel in tier 1, so that the
41 security-conscious has something "tier-1 supported & security-enhanced"
42 to put on its servers. I would vote for grsec-sources, as it is just
43 vanilla+grsec patch, so it's not too hard to maintain ?
