The only problem with that approach is that you can't have any symlinks
in the actual created filesystem in that case...
And regarding Listener (inotify), as far as I can see inotify can send
an event when a file is created or moved there. But we don't want to
create or move any data there! The original file should be kept where it
is, and we don't want to copy the data when it's theoretically not
needed. Here's what I've thought with using FUSE:
~] fusemkiso MyISO
#The dir is created if non-existent, if the dir existed and wasn't empty
#- exit with an error...
~] cd MyISO
~/MyISO] cd Root
~/MyISO/Root] ln -s ~/Foo .
~/MyISO/Root] ln -s ~/Bar.txt .
#internal references is stored in the fs, it's not actual symlinks...
#an ls -l would show the real filesizes
~/MyISO/Root] cd ..
~/MyISO] cp MyISO.iso ~/
#as the MyISO.iso file is read, a real iso image is now created
#you could also just burn this iso image from here without copying it
~/MyISO] cd ..
~] fusermount -u MyISO
#unmounted... could fusemkiso detect the unmount and write the iso image
#on stdout (if cmdline option was specified), so that it could be piped
#into a DnD savebox GUI... And also delete the mountpoint if it wasn't
#existing at startup...
