To bootstrap CentOS in Gentoo, I did the following. It basically installs the essential CentOS components into the specified directory, and from there on, chroot into that directory and perform tests, etc. First off, you’ll need to unmask a few packages(replace ~amd64 with ~x86 if your on the x86 architecture), and enable the flag sqlite for rpm. Execute the following commands as root:<\/p>\n
# echo sys-apps\/yum ~amd64 >> \/etc\/portage\/package.keywords\r\n# echo dev-python\/sqlitecachec ~amd64 >> \/etc\/portage\/package.keywords\r\n# echo app-arch\/rpm sqlite >> \/etc\/portage\/package.use<\/pre>\n
\nNow we’re ready to install the primary packages required to bootstrap CentOS. Merge the following atoms: sys-apps\/yum app-arch\/rpm dev-python\/m2crypto as<\/p>\n# emerge -avuDN sys-apps\/yum app-arch\/rpm dev-python\/m2crypto<\/pre>\n
\nIn this example, we’ll bootstrap CentOS 5(x86_64). Download the stage2(sounds like gentoo now, huh?) from any CentOS mirror. The minimal stage2 does not work with this process.<\/p>\n# wget http:\/\/mirrors.seas.harvard.edu\/centos\/5.6\/os\/x86_64\/images\/stage2.img<\/pre>\n
\nYou need to extract the contents of this squashfs image file, so make sure you have =sys-fs\/squashfs-tools-3.1 installed. The latest one in portage is broken. Execute the following:<\/p>\n$ unsquashfs-3.1 -d \/devel\/centos5 stage2.img<\/pre>\n
\nNow we have a working CentOS 5.6 installation. Install bash and yum into it before you can finally chroot.<\/p>\n# yum --installroot \/devel\/centos5\/ --nogpgcheck install bash\r\n# yum --installroot \/devel\/centos5\/ --nogpgcheck install yum<\/pre>\n
\nThe –nogpgcheck is so that yum doesn’t check the gpg keys which are currently missing on your host gentoo system, or any other non-rpm distribution. chroot into \/devel\/centos5 and perform some cleaning:<\/p>\n# chroot \/devel\/centos5\r\n# mkdir \/old\r\n# mv \/var\/lib\/rpm \/old\r\n# yum install yum\r\n<\/pre>\n
\nWhat did you just do? Well the RPM DB generated by your host distribution’s RPM, will certainly not match CentOS’s yum, hence we remove the stale RPM database. Everything in the stage2 comprises only of the dependencies of yum and yum itself. Doing a yum install yum will fix everything.
\n
\nCongratulations, you now have the base CentOS installation in \/devel\/centos5 These instructions are not limited to Gentoo alone, but to any distribution. Any questions may be posted as comments, and I’ll be glad to help you out.<\/p>\n","protected":false},"excerpt":{"rendered":"To bootstrap CentOS in Gentoo, I did the following.
