Re: interface for tar
Sharchar:
Can I do that with autofs? Lets say I have a directory called
/home/$userid/image_files; can I have autofs to look for
/home/$userid/& and automatically mount and unmount these fs images?
Lets say I keep the fs images in /home/$user/.isos
ANy thoughts about this?
Either way, thanks for all of your help guys!
TIA
