Upgrading the Qube

I have just finished running the upgrade process for the Qube. Given the OS was published in 2001, there are 73 upgrades and order is significant. I told you in my article on Tuesday, that I had found some Sun resources to help me, these include a Sun hosted user forum, a search reply on key word Qube from SunSolve, & this Sunsolve article \*documenting the patch install order. A further resource of some use is at http://hitechsavvy.com here....

This is in fact my second attempt at doing this, so I know that my plans to install ssh will at the least generate a warning because the distributed version of zlib is less than current and has known security vulnerabilities, which the ssh configure process identifies. The Sun Page above (see \*) states that a zlib patch should be installed. This was not discovered by my Qube's web form, but I installed it manually. The Qube 3 patch site is at Sun here.... I couldn't find a bookmark feature for the patches themselves. The zlib patch is called "Qube3-All-Security-4.0.2-16487 ("zlib" security update)" and its current Sun URL is here.... The manual install is neat, but the persistant requesting for permission to proceed and the multiple reboots makes the whole task long and tedious, and requires constant intervention. I assume that the failure to improve this is part of Sun's "management" of the Cobalt product range.

Its possible that automating software updates, with a rigorous dependendcy management functioanlity is a difficult problem to solve as my experience with other Linux distro's software update mechanisms has not been particularly happy. I'd also need to look at Sun's current solaris offering and see if we've learned anything from the Cobalt experience before I make a final judgement. I'd have thought it was easier with an appliance; the vendor has a right to expect more control. The only build standard is the appliance vendor's.

Anyway its done now!
