[Michael G. Morey]

I'm attaching the output of:

/usr/bin/ltrace -S -f -o /root/sulogin-trace.log /sbin/sulogin

called from /etc/init/mountall-shell.conf (modified).

Title:
  sulogin crashes if root password is "x"

Status in “sysvinit” package in Ubuntu:
  New

Bug description:
  There is no check for the pointer return value of library call crypt()
  before the pointer is used by strcmp().  This results in a
  segmentation fault and prevents the maintenance shell from running at
  system start-up if there is a problem mounting one or more
  filesystems.
