[Pkg-sysvinit-devel] Bug#490893: Bug#490893: initscripts: reboot fails to unmount '/'

[Subhashis Roy]

Hi Peter,

Thanks for your prompt reply.

I find that '/etc/init.d/portmap' has permission to execute.
However, I checked by writing a small line within '/etc/init.d/portmap' 
Stop that it is not getting called.

Attached is the output of 'ls /etc/rc[06].d'.

Also, 'ls -ltr /etc/rc[06].d/*port*' shows:
lrwxrwxrwx 1 root root 17 Sep 10 11:24 /etc/rc6.d/S32portmap -> ../init.d/portmap*
lrwxrwxrwx 1 root root 17 Sep 10 11:24 /etc/rc0.d/S32portmap -> ../init.d/portmap*

I am also attaching the '/etc/init.d/portmap' (before my change) file as 
in my machine, in case you want to examine it (I can easily circumvent 
this problem by killing 'portmap' separately during 'reboot' in a script, 
but is not a good choice in general).
