Managing security upgrades?
The number of (Ubuntu) servers I have is growing steadily, and with it approaching 10 (including VM's), I'm starting to look for a solution to manage security upgrades beyond the apt-get update && apt-get upgrade mantra.
What are other people using for this? I know RH Satellite/Spacewalk is nice but it's only for RHEL-derivates.
Already looked at unattended upgrades, but I'd like something with a little more options and centrally managed (I have redundant web frontends so they should be upgraded sequentially).
Are there any standard solutions out there (not landscape)? Or should I script it from scratch?
