Bug#488865: initramfs-tools: buggy check for read-only /boot

[Zbyszek Szmek <zbyszek@in.waw.pl>]

Package: initramfs-tools
Version: 0.85h
Severity: normal
Tags: patch


The script /usr/sbin/update-initramfs checks if /boot is mounted read-only,
and aborts if so. Unfortunately, the test also triggers in other cases, 
e.g. on option errors=continue (because this phrase contains 'ro').

A simple fix (check for 'ro' delimited by commas or the begging or the 
end of options string):
