Re: allow ^C to interrupt /etc/rc.local

2011-02-26 Thread jidanni 
OK, thanks everybody. I came up with a workaround since ^C doesn't interrupt:
$ tail /etc/rc.local
echo  $0:
Will execute \${program=/etc/init.d/nodm start}\ in ${seconds=5} seconds.
  Hit some chars and RET to cancel.
  Hit RET to start right away.
for ((; seconds  0; seconds--))
do
read -p $seconds.. -t 1
case $? in 0) #they hit RET...
case $REPLY in
'') break  ;; #...with no other chars
*)  exit 44;; #...with other chars
esac;;
esac
done
echo running $program...
$program

Oh, I'm betting someone knows and they either didn't get your message (because 
they aren't on the list) or didn't reply (because they didin't want to spend 
their time that way).
 
 /boot/grub/grub.cfg:
 menuentry 'Debian GNU/Linux, with Linux 2.6.37-1-686 (recovery mode)'
 
 do to the terminal in order to enable interaction after one enters the
 root passwd?

It doesn't do anything special.  /sbin/init runs /sbin/sulogin (which may or 
may not prompt for a pasword) on that vt.  It does this because the single 
kernel command-line argument included in that menu entry has init start in the 
S runlevel.

I'm not sure that /etc/rc.local is run with a controlling terminal.  Sure, 
it's output appears on the console, but that can certainly be done without 
having a controlling terminal.  If is doesn't have a controlling terminal, it 
is likely difficult to impossible to has it receive Ctrl+C, since some program 
attached to the terminal will swallow the key event (possibly, but not 
necessarily sending SIGINT to selected children as it does).

Hi,

On Thu, Feb 24, 2011 at 02:56:55PM +0800, jida...@jidanni.org wrote:

I think this put system to something like runlevel S or 1
 
 do to the terminal in order to enable interaction after one enters the
 root passwd?

When system goes though runlevel S, there is some SULOGIN things:

$ grep -i login *
S02early-readahead: if [ -d /proc/1 ]  [ ! -e /proc/1/loginuid ]; then
S08checkroot.sh:[ $SULOGIN ] || SULOGIN=no
S08checkroot.sh:# Set SULOGIN in /etc/default/rcS to yes if you want a 
sulogin to
S08checkroot.sh:[ $SULOGIN = yes ]  sulogin -t 30 $CONSOLE
S08checkroot.sh:if ! sulogin $CONSOLE
S08checkroot.sh:if ! sulogin $CONSOLE
S12checkfs.sh:  if ! sulogin $CONSOLE
S25bootmisc.sh:[ $DELAYLOGIN ] || DELAYLOGIN=yes
S25bootmisc.sh: # If login delaying is enabled then create the flag file
S25bootmisc.sh: # which prevents logins before startup is complete
S25bootmisc.sh: case $DELAYLOGIN in
S25bootmisc.sh: echo System bootup in progress - please wait  
/var/lib/initscripts/nologin
S25bootmisc.sh: # Create /var/run/utmp so we can login.
S25later-readahead: if [ -d /proc/1 ]  [ ! -e /proc/1/loginuid ]; then
S26stop-bootlogd-single:# a call to /sbin/sulogin, while runlevel 1 is a call to
S26stop-bootlogd-single:# /sbin/sulogin.


OK, I found
S08checkroot.sh:[ $SULOGIN = yes ]  sulogin -t 30 $CONSOLE

It has comments:
# Set SULOGIN in /etc/default/rcS to yes if you want a sulogin to
# be spawned from this script *before anything else* with a timeout,
# like sysv does.

See sulogin(8).

Cheers.

Osamu

allow ^C to interrupt /etc/rc.local

2011-02-23 Thread jidanni 
Gentlemen, at the bottom of /etc/rc.local I have:
  echo  $0:
  Will execute \${program=/etc/init.d/nodm start}\ in ${seconds=5} seconds.
Hit ^C to cancel.
Hit RET to start right away.
  for ((; seconds  0; seconds--)); do read -p $seconds.. -t 1  break; done
  echo running $program...
  $program
The problem is of course that ^C is ignored when running /etc/rc.local .
I have tried putting set -i, stty, trap '' INT, you name it, into
/etc/rc.local . They all don't work. The best I can do is to type
something and then a RET, and evaluate that, which is not as fun as ^C.
