Re: getting speech feedback as you boot/reboot

[Hans Zoebelein <hzo@xxxxxxxxxxx>]

This adapted 'functions' file which comes as attachment will even tell you
the results after a service was started/stopped. 

Possible answer will be 'OK', 'failed' or 'passed'. The 'passed' answer
will shine up after a partition was successfully checked with 'e2fsck'.
As usual: back up your original 'functions' file and make sure that
you can access your box using a boot floppy (which also holds a root 
directory) or another partition.

Enjoy!
Hans
