<br></div><div>Having said that, I would still understand and support any box-admin who wanted some testing first. If something is already _proven_ working in production, not crashing, and we're not really having any immediate production impetus to upgrade it, then this almost amounts to "testing in production". No benefit, but a small chance for a problem. There's plenty of time and opportunity to shake them out in test environments first.</div>

<div><br></div></div><div>Given that 3018 has nothing radically new but contains bug fixes IMO it is stable. Even the SPur VM is more stable than the one that preceeds it. What extra testing has 2776 had to make it more or less stable than 2987 or 3021? 2987 and subsequent all run the standard test suite with equivalent results. I don't make arbitrary changes to the Cog VMs (Spur is obviously evolving much faster, but again is getting more, not less stable). You need to specify a criterion by which a VM is judged stable, not merely go by age, which is, at least on average, inversely correlated with stability, older VMs containing more bugs, if you want to argue against using newer VMs. I don't put newer VMs out for amusement. I put them out because they're better (faster, fix bugs, etc).</div>

Installing:<br>
<br>
- get a Cog binary from <a href="http://mirandabanda.org" target="_blank">mirandabanda.org</a><br>
- use Ken's cogdeb.zip to make a deb<br>
- install with dpkg (i.e. dpkg -i cogvm_2776-1_i386.deb)<br>
- execute "man squeak" to see if it's loaded<br>
<br>
Removing:<br>
<br>
- check the package name with dpkg-query -l<br>
- see it's actually called "coglinux" as opposed to cogvm or squeak<br>
- dpkg -r coglinux<br>
<br>
<br>
So, as I said, I just did this on my server and is seemed to work OK. I plan to upgrade the VM from last year's model (2776) to this year's (2987). If there's anything people with more LInux experience could add to this process, I'd be happy to hear it.<br>
