Default telinit 1



Hello i noticed something if i telinit 1, go into single user mode.
I'm not truelly in single user mode i can login using various accounts on
all 3 of my virtual consoles, the other 2 vc's tty2 tty3 don't get locked
down.

It's weird this didn't happen in slackware 10 IIRC
I haven't made any changes to rc.K

# These are the default runlevels in Slackware:
# 0 = halt
# 1 = single user mode
# 2 = unused (but configured the same as runlevel 3)
# 3 = multiuser mode (default Slackware runlevel)
# 4 = X11 with KDM/GDM/XDM (session managers)
# 5 = unused (but configured the same as runlevel 3)
# 6 = reboot

# Default runlevel. (Do not set to 0 or 6)
id:3:initdefault:

# System initialization (runs when system boots).
si:S:sysinit:/etc/rc.d/rc.S

# Script to run when going single user (runlevel 1).
su:1S:wait:/etc/rc.d/rc.K

# Script to run when going multi user.
rc:2345:wait:/etc/rc.d/rc.M

Any suggestions on how to resolve this:

Many thx in advance, greetings

Kevin

This is perfectly normal.

Actually, this has been the default for Slackware for as long as I can
remember.

Don't bother. There's nothing wrong. However, if you are concerned
about it, the magic is in these lines:

# These are the standard console login getties in multiuser mode:
c1:1235:respawn:/sbin/agetty 38400 tty1 linux
c2:1235:respawn:/sbin/agetty 38400 tty2 linux
c3:1235:respawn:/sbin/agetty 38400 tty3 linux
c4:1235:respawn:/sbin/agetty 38400 tty4 linux
c5:1235:respawn:/sbin/agetty 38400 tty5 linux
c6:12345:respawn:/sbin/agetty 38400 tty6 linux
^

In all of those tty's, run-level "1" is specified to have them active.
If you remove the "1" from a line, that tty won't be active for
run-level "1". Note how only tty6 is available for run-level "4" by
default.

# Runlevel 4 used to be for an X window only system, until we discovered
# that it throws init into a loop that keeps your load avg at least 1 all
# the time. Thus, there is now one getty opened on tty6. Hopefully no one
# will notice. ;^)

Wow thx but i think suse 7.2 / 9.0 had them disabled then. Anyway it was a
long time ago i needed to go telinit 1. But now sometimes if netdisk smb
share timeouts: i try to unmount my binded dirs to that smb share, then
the smb share mount itself and then ... the mount on my disk and then it
keeps complaining about filesystem busy blablabla and telinit was the only
thing to resolve this issue. But thx i never knew what the second field in
the inittab meant. 2 bad because now if you tell me its pretty straight
forward >>> c6:12345:respawn:/sbin/agetty 38400 tty6 linux <<< hahahaha; 2
simple !
