[PATCH] improve process-status output, including initctl list

[David Jeske]

I've attached the patch I'm using to make my initctl display output (list)
more human readable..

I don't have m4-fu, so I wasn't sure how to change the build properly.. it
needs "-lproc" and "-I/usr/include/proc"

I decided to just show days in floating point, since that seems about as
much precision as folks typically need here and it's easy to read.

The output looks like this:

root at w5:~/src2/upstart-0.6.5/util# initctl status mysql
   start/running       5.13d    10652 mysql

root at w5:~/src2/upstart-0.6.5/util# initctl restart willow-smtpd
   start/running       0.00d    14700 willow-smtpd

root at w5:~/src2/upstart-0.6.5/util# initctl list
   start/running      44.14d      634 rsyslog
   start/running      44.14d      675 tty4
   start/running      44.14d      308 udev
   start/running      44.14d      304 upstart-udev-bridge
    stop/waiting                      mountall-net
    stop/waiting                      rc

Enjoy.
