Invalid ps busybox option '-a' when starting or stopping cups

[Andrew McDermott]

I noticed the following error when booting a Lamp image:

ps: invalid option -- 'a'
BusyBox v1.20.2 (2013-06-20 10:32:04 BST) multi-call binary.

Usage: ps

130620 11:38:02 mysqld_safe Starting mysqld daemon with databases from /var/mysql
cupsd: Child exited with status 1
cups: unable to start scheduler.

This can be reproduced by running:

  /etc/init.d/cups stop

or

  /etc/init.d/cups start

This can be fixed by installing the full procps packages or by fixing up busybox.

Adding procps is easy, fixing busybox a bit harder, so which option is preferred?

+1 to add procps
