Bug#442289: 25configure_init Mangles ttyS Lines in /etc/inittab

[debian-bugs at ssorensen.fastmail.fm (Svend Sorensen)]

Package: live-initramfs
Version: 2.3.6.ds1-13

The 25configure_ini file 
(/usr/share/initramfs-tools/scripts/casper-bottom/25configure_init) 
mangles the ttyS[0-9] lines in /etc/inittab.  This is due to the sed 
expression on line 54:

sed -i -e "s|^\([^:]*:[^:]*:[^:]*\):.*getty.*\<\(tty[0-9]*\).*$|\1:/bin/login -f $USERNAME </dev/\2 >/dev/\2 2>\&1|" /root/etc/inittab

The regex "tty[0-9]*" matches ttyS0, but only saves the string tty.  
This results in lines which contain /dev/tty on boot.  If the serial 
console line is uncommented in the original /etc/inittab, the system 
fails to open the serial console on boot due to /dev/tty not existing.

This could be fixed by:

1. Changing the regex so that ttyS* lines are not matched: 

    "tty[0-9][0-9]*"

2. or saving the entire ttyS* filename:

    "ttyS\?[0-9]*"

    (This regex contains "\?" which is a GNU extension to sed.)
