When initializing the db with tripwire --init it spat out a bunch of errors pertaining to /proc:

### Warning: File system error.
### Filename: /proc/16982/fd/4
### No such file or directory
### Continuing...
### Warning: File system error.
### Filename: /proc/16982/fdinfo/4

### Warning: Duplicate object encountered.
### /proc/sys/net/ipv6/neigh

This feels like noise. The twpol.txt file has the following clause:

#
# Critical devices
#
(
  rulename = "Devices & Kernel information",
  severity = $(SIG_HI),
)
{
        /dev            -> $(Device) ;
        /proc           -> $(Device) ;
}

Which, if I understand it right, is going to cause tripwire to care deeply about the entire contents of /proc. Shouldn't it just care about the static parts of /proc like the drivers and such, and not the per-pid stuff? Why does it ship like this?

...and if so, how?

I'm using Apache2 + mod_fcgid to serve a perl Catalyst application, on a box that I own, and I'd like for mod_fcgid to maintain a minimum number of spun-up processes ready to go. The docs say that FcgidMinProcessesPerClass only enforces a

minimum number of processes that will be retained in a process class after finishing requests

How do I get apache to start up with a certain number of appserver subprocesses on an idle server without using artificial load to get there?

I know, I know, I should switch to Postfix. But in the meantime, how do I throttle outbound email (especially email to a single domain) in Sendmail?
