[Bug 619817] [NEW] grep -o causes infinite loop

[Jonas Bonn]

Public bug reported:

Binary package hint: initramfs-tools

Bringing up initramfs busybox shell and executing following command
causes an infinite loop:

cat /proc/meminfo  | grep MemTotal | grep -o "[0-9]*"

This is, of course, a problem if the same command is issued in a script.
The culprit is the "-o" option on the last grep...

** Affects: initramfs-tools (Ubuntu)
