kernel tries to exec zero-length file
Last modified: 2008-05-01 11:37:54 EDT
Create a zero-length file. Make it executable.
Modify /etc/syslog.conf to log *.debug into a file. Create the empty log
file and send a HUP to syslogd.
Try to execute the zero-length file. In your debug syslog log file, you'll
see, "modprobe: modprobe: Can't locate module binfmt-0000".
The kernel should not be trying to load a module to execute an empty file.
Its an interesting question since there is no kernel problem with leavign this
allowed. I suspect someone should by default 'alias binfmt-0000 off'
will be done in 2.4.6-1.
