Any reason why 5 is not a symlink to 5.7 whereas 4 is a symlink to 4.8? Looks like the same applies to 6!?!
----- Original Message ----- | -----BEGIN PGP SIGNED MESSAGE----- | Hash: SHA1 | | We are pleased to announce the immediate availability of CentOS-5.7 | for | i386 and x86_64 Architectures. | | CentOS-5.7 is based on the upstream release EL 5.7 and includes | packages from all variants including Server and Client. All upstream | repositories have been combined into one, to make it easier for end | users to work with. | | This is just an announcement email, not the release notes. The Release | Notes for CentOS-5.7 can be found on-line at : | http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.7 and everyone is | encouraged to look through them once. Also worth browsing through are | the CentOS FAQs at http://wiki.centos.org/FAQ | | +++++++++++++++++++++++ | Upgrading from CentOS-5.6 ( or CentOS-5.0/5.1/5.2/5.3/5.4/5.5): | | If you are already running CentOS-5.6 or an older CentOS-5 distro, all | you need to do is update your machine via yum by running : | | 'yum update' | | Running 'yum list updates' before doing the update is recommended, so | you can get a list of packages that are going to be updated. To check | you are indeed on CentOS-5.7, run : 'rpm -q centos-release' and that | should return: 'centos-release-5-7.el5.centos.1' | | If you are running CentOS-5.6 and have the CR repo enabled, a simple | 'yum update' will still move your machine to 5.7. But since the CR | repo | already contained all the 5.7 updates, there will only be a handful of | rpms that need to be installed for the 5.6 to 5.7 upgrade. If you are | not running the CR repo, we highly encourage everyone to install and | run | this repository on their machines. More details on the CR repo can be | found online at | http://wiki.centos.org/AdditionalResources/Repositories/CR | | +++++++++++++++++++++++ | Downloading CentOS-5.7 for new installs: | | When possible, consider using torrents to run the downloads. Not only | does it help the community and keeps mirrors from running up high | bandwidth bills, in most cases you will find its also the fastest | means | to download the distro. There are currently over a hundred people | seeding CentOS-5 and it's possible to get upto 100mbps downloads via | these torrents. | | - -- Via BitTorrent : | CD: | http://mirror.centos.org/centos/5.7/isos/i386/CentOS-5.7-i386-bin-1to8.torre... | http://mirror.centos.org/centos/5.7/isos/x86_64/CentOS-5.7-x86_64-bin-1to8.t... | | DVD: | http://mirror.centos.org/centos/5.7/isos/i386/CentOS-5.7-i386-bin-DVD.torren... | http://mirror.centos.org/centos/5.7/isos/x86_64/CentOS-5.7-x86_64-bin-DVD.to... | | md5sum's for these torrent files: | | 8e29e525f45c4a7b3a963cc01ec3459a CentOS-5.7-i386-bin-1to8.torrent | 32c9e0826b50d6be44823523be403c7f CentOS-5.7-x86_64-bin-1to8.torrent | 795d6c11b5ef8907653360af52b9f317 CentOS-5.7-i386-bin-DVD.torrent | 04c563f2c838bf6b255fcc5fcc18cf66 CentOS-5.7-x86_64-bin-DVD.torrent | | sha1sum's for these torrent files: | | 8a945ba89b03328480fde20eaa0b638ceb7f4509 | CentOS-5.7-i386-bin-1to8.torrent | b1a18ba25e77543c4df9078dfafba990fbd58601 | CentOS-5.7-x86_64-bin-1to8.torrent | d3c4ed0d14fe1873bbcee931224e5e8819f779dc | CentOS-5.7-i386-bin-DVD.torrent | 302850dd4f9a8198b303f872c83a5a16ec1c40c2 | CentOS-5.7-x86_64-bin-DVD.torrent | | | While torrent files will do their own content checks, and only the | right | torrent will register and download from torrent.centos.org - its very | important for your own security that an md5/sha1sum check is done on | the | .torrent file itself, and ensure that only the torrent.centos.org | tracker is being used.

yeah I noticed that they've changed that. in 4.x, cd centos; ln -s 4 4.8 but in 5.x+, its more like,
cd centos/5.7 for i in *; do ln $i ../5/$i; done

Yes, I did notice that, just wondered why. It seems more prone to breakage (creating multiple symlinks vs one)

There are a couple of reasons. I wont go into all, but the 2 that stick out the most for me are:
1) symlinking a step deeper means we can have more finer grained control over the content exported from the <release>/ and the <release>/<repo> level, specially when it involved shared content ( Extras as one functional example, addons and contribs as another - but non impacted here )
2) This is the more important one : with /6/ and 6.X/ being real physical locations there is still the door open that allows /6/ to become the CR repo. Entirely, across the OS/ and Updates/+ CR/ whereas 6.X/cr/ then becomes local to what is representative of a next-release content repo ( in relation to the point release its injected into ). This becomes even more relevant when you factor in 'CR/ content will not move to vault.c.o when the <release>.X content does'. Furthermore, this is an important issue when we consider that the CR repo is opt-in, having a /6/ stream that is always updated and always just-usable irrespective of what 6.X one installs on their machines is always going to be a good goal to achieve, imho. Impact on how we do things, how we store stuff, stage content, get it into the mirrors, export to users and yum clients : massive. Ofcourse, the only experience that needs to be protected is the yum-client interface, and can we achieve this refactor without impacting yum-client interfaces ? I dont know. What I do know, is that very very few external mirrors have the capacity to handle something of this nature. Solve'able problems no doubt.
There are also site-specific benefits like being able to add and track local repo's without needing to add in hackery over the centos mirror rsync exported content within a <release>/ or <release>.X/ tree. And for people who run multiple machines, or need to have different production environments this tends to be quite a big deal.
From the user perspective, it should not make a difference as to where
the symlinks are setup to -> from. If there is an impact, do tell.
