Gentoo is one of those distros where you can practically upgrade any old version to current without a re-install. I’ve had gentoo boxes migrate between arches without reboots.
That said, there are some tricky bits during some migrations. Are these critical instances or can they have some downtime? Basically, you’ll want to do: emerge --sync emerge -puD world See what it’s doing, or complaining about, and then to actually update everything emerge -uD world you’ll also want to install the gentoolkit emerge gentoolkit Post install, you’ll want to run revdep-rebuild from the gentoolkit to ensure that all the system links are valid after the update. ~Rob On Dec 6, 2013, at 12:29 PM, Adam Quigley <adq...@gmail.com> wrote: > I've inherited some older gentoo instances and I've been asked to upgrade > ruby to the current patchlevel but I have no idea how to do that. > Documentation is coming up sparse or I don't know what to search on. > > /etc/gentoo-release says Gentoo Base System release 2.1 if that helps. > > I did find this doc on portage. > http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1 > > The few emerge commands I have run seem to indicate it's old and needs help. > > I wonder if it's old enough that I'll need to do a major system upgrade to > do the ruby upgrade. > > Basically I'm looking for something that's similar to "apt-get update && > apt-get dist-upgrade" that can get me an updated system. > > Thanks, > > -adam
