Gentoo portage updates through mirrors by default are insecure and I'm
not sure everyone knows what's doing already considering it's not the
default and if I talk to people they're not aware about it. So I
thought it's appropriate to send a reminder considering your topic...
To be secure if you use Gentoo you need to add webrsync-gpg to
FEATURES in make.conf and then use only emerge-webrsync (and never use
emerge --sync). Then you should be safe, after that the
SHA1/SHA256/RMD160 of every further download is verified against the
Manifests which have been cryptographically signed. It's very naive
and too insecure to trust any random mirror and emerge --sync should
be abolished and webrsync-gpg should be the default in FEATURES. After
you see "Good signature from" in output from emerge-webrsync you
should be safe. tarsync then speed things up.
