Yes they are similar in that both can draw graphs but that's about where the similarity ends. Munin's job is to periodically poll a device using whatever means is available and gather data from the device. The data is always in the form of a number - it measures something. The data can be anything you can generate a number for - logged in users, traffic through an interface, load, number of database queries. The list is endless. Point being, the device/computer/hosts reports it's own numbers to munin, and munin draws graphs. Munin does not record state, it has no idea what the state of something is. Nagios is a problem child, it does not do what people assume it does (I have constant fights about this at work). Nagios is a state monitoring and reporting engine (simply because this is what it does well and everything else it does it does poorly). Nagios will track if things are up or down, if you acknowledged the condition and when, who to notify when state changes (sms, mail, dashboard etc etc). What Nagios does poorly (despite this being it's advertised purpose) is getting state events into the system. It really really sucks at this and is coded from an extremely narrow point of view.

There has been a discussion on that in this list, and there is some concern that ZFS' license (CDDL) is not compatible with the Linux kernel license (GPL), so never the twain shall be integrated. That said, if your kernel supports modules, it's a piece of cake to compile the ZFS modules on your own. @ryao has a zfs-overlay you can use to emerge ZFS as a module. If you have configured your kernel to not support modules, it's a bit more work, but ZFS can still be integrated statically into the kernel. But the onus is on us ZFS users to do the necessary steps.

[gentoo-user] trouble installing cups
When I reinstall CUPS /etc/cups/cupsd.conf is *not* updated. Details follow. Cups was behaving badly: the web interface could not be used. The browser would quickly say no process was listening on localhost:631 I compared cupsd.conf to the same file on another working system and noticed the following differences 1. *Many* pairs of lines were missing. The first line of each pair was blank; the second a comment. Presumably this has no effect. 2. The initial block comment was missing. Again no effect. 3. One very influential change Listen localhost:631 was replaced by a second copy of Listen /run/cups/cups.sock When I manually put back localhost:631 the cups web interface again behaved normally. 4. The following block was *added* at the end JobPrivateAccess default JobPrivateValues default MaxLogSize 200 SubscriptionPrivateAccess default SubscriptionPrivateValues default The first, second, fourth, and fifth generated "Unknown directive" messages in /var/log/cups/error.log So I reinstalled cups but /etc/cups/cupd.conf was not changed and still has its old date and contents. The merge looks clean (output below) I am wondering if there is something wrong with my setup. I have the userpriv feature enabled.

RAID 10 pretty intuitively comes from RAID 1+0, which can be read aloud to figure out what it means: "RAID 1, plus RAID 0," i.e. you do RAID 1, then stripe (RAID 0) the result. The trick is that RAID 1 can refer to either mirroring (2-way) or multi-mirroring (3-way) [1]. In the end, the designation is the same: RAID 1. So if you stripe either of them, you wind up with RAID 10. In other words, "RAID 10" doesn't tell you which one you're going to get. If I ever find a controller that will do multi-mirroring + RAID 0, I'll let you know what they call it =) [1] http://www.snia.org/tech_activities/standards/curr_standards/ddf

I just noticed you are checking for display and xauthority in the environment.
Udev processes events when they come in. I doubt you are logged in when the
