Rsync will let you preserve hardlinks (and we've got a lot of them) which should translate into less space used on your end. http://www.scientificlinux.org/download/mirroring/mirror.rsync Pat Got an rsync of the 6.4 repo done and set up one system to use it and that system still does not see the newer autofs contained in the base os repo. Not sure if there are other packages in this same state, autofs is one that we use heavily here so any updates to it are noticed pretty quick. When I saw that it was available in the 6.4 repo and noticed that none of my 6.4 systems were getting that update it raised a flag. I can still run a yum localupdate path to new autofs and it works just fine.

Bootable USB installer for SL6.3
For reasons unknown, RHEL and SL insist on publishing installer images that work only from the DVD physical media. But none of the computers I buy today have DVD drives and I am not sure if Staples carry DVD blanks anymore. I guess I must be happy that SL install images do not come on floppies, punch cards or paper tape. Generally, this does not inconvinience me too much - I do most installs over the network (PXE boot). But sometimes I have machines generally not connected to the Internet (on a private network or out in the woods), so I have constructed bootable USB images for SL6.1 and 6.3. (6.4 on the way). (This installer tree is a copy of the .../x86_64/os tree minus the Packages directory, plus the isolinux/extlinux stuff and the DVD .iso files. The SL installer refuses to install from the Packages directory) (There is one caveat with running the installer from writable media - the SL6.3 installer sometimes writes the GRUB boot loader on the USB installer disk instead of the installation target disks - producing an unbootable system and ruining the USB installer disk at the same time. I have not seen the SL6.1 installer do this. Maybe one should use write-protect capable USB flash media). Download the stuff from here: http://trshare.triumf.ca/~olchansk/linux/ Instructions are here: http://trshare.triumf.ca/~olchansk/linux/SL63-64-USBBOOT/AAA-README-USBBOOT.txt Instructions for making USB-Bootable installation disk for 64bit SL6.3 -- 0.

(In some cases, as with the current Nvidia CUDA 5 setup, we do out of necessity.) Thank you for the contribution. A related question: is there a way to burn an update DVD that will contain the files that your script downloads and uses so that the update can be burned on a machine with decent network bandwidth (e.g., accessing the LambaRail or whatever the current name is for this research backbone) and then utilized locally without accessing any network? In other words, going to the repo list authorized for a machine -- how does one get just the updated (update) rpm (etc.) files that are needed and how does one organize these on the DVD image so that your script will use these from said DVD? Use rsync to download the files to a directory. Burn the files to media. Modify the /etc/yum.repos.d/ security config file to point to the dvd. Since rsync only downloads changed/new files then the bandwidth is less than copying the full directory all the time. If the local network is faster you could change the /etc/yum.repos.d/ security config file to point to your mirror that you created above. -Connie Sieh Thanks, Yasha On 04/11/2013 09:57 AM, Konstantin Olchanski wrote: Yasha - of all possibilities you always choose the most painful, without fail.
