Hey, I'm going to setup Gentoo binary package server for LXC and Docker containers that will be used on the production server.
On the server I already have hardened profile, so the my question is whether using hardened profile on the containers will be beneficial in terms of security or if it is sufficient to leave normal default Gentoo profile default/linux/amd64/23.0/systemd. I'll use these containers both for testing locally development applications on my laptop before deploying them, and also on the production server. I use this server mainly for hosting my own personal stuff like PHP websites, mailing lists, Jabber server, Git repositories. I want these containers to be easily deployable on different environments, and portable so I should set in CFLAGS, CXXFLAGS etc. -O2 -pipe, without -march=..., right? Thank you in advance for helpful answers, whiteman808.
