A preface first: |

|
| 3 |
Lots of love for Gentoo, it seems :-) |
| 4 |
|
| 5 |
I'm now positive in pushing a full-fledged Gentoo infrastructure in my |
| 6 |
office (complete with Gentoo maintenance support VMs) |
| 7 |
|
| 8 |
And, as I promised, I'll publish your stories in my blog (currently |
| 9 |
undergoing migration from b2evo to TikiWiki). |

to several mysql database servers, xen cluster with livemigration, ietd |
| 17 |
iscsi targets, apache webserver, radius, postfix mailservers with pop3 and |
| 18 |
imap postboxes for several hundred clients and syslog server. |

That depends on what Kai meant with "uptime". Maybe he meant the VMs (he's |
| 34 |
using Xen, after all) never needs a restart, but the BIND service still gets |
| 35 |
regular update and the consequent service-restart. |

Xen or XenServer? Well, they're both Xen, anyways :-) |
| 43 |
|
| 44 |
In my office I use XenServer, and Gentoo VMs on Xen(Server) truly are the |
| 45 |
epitomes of stability. I had had 2 'U' servers froze after restart, 1 'A' |
| 46 |
server went wacky after installing a package, and a 'D' server consuming CPU |
| 47 |
for reasons unknown. |
| 48 |
|
| 49 |
(Well, one Gentoo server indeed consumed CPU, too, but not surprising since |
| 50 |
it's the gateway/firewall handling 5 (five!) WAN connections) |
| 51 |
|

>> Maintaining these server is pure fun. Im just convinced that Gentoo is |

made for datacenters ;) Well of course managing all these portage trees and |
| 54 |
keeping software up to date can keep you busy for some time but I assume |
| 55 |
that this is not different to any other distri. |

Indeed! It's a battle trying to get other distro's to have a local support |
| 59 |
infra. |

How I wish I can do that :-( |
| 68 |
|
| 69 |
Currently I'm forced to use Windows on the workstation because there are |
| 70 |
some custom-made apps that can run only on Windows... *sigh* |
