thanks

Firstly sorry for getting the wrong version... must be more careful
with manually crafted bug reports.

Secondly the "fix" in incoming (0.80) has code that looks like this:


ro_boot_check()
{
	[ -d /proc ] || return 0
	boot_opts=$(awk '/boot/{if (match($4, /ro/)) print "ro"}' /proc/mounts)
	if [ -n "${boot_opts}" ]; then
		echo "WARNING: /boot is ro mounted."
		echo "update-initramfs: Not updating ${initramfs}"
		exit 0
	fi
}



Even on chroot systems with /proc unmounted there is likely to be a
/proc directory (as a potential mount point). Thus the test [ -d /proc
] is likely to be TRUE all the time... even when proc is not mounted.
A better test would be:
 [ -r /proc/mounts ] || return 0
Which would o test for the readability of /proc/mounts which is the
file we want to read in the next line!
