This method is a redesign based on former, supposedly dedicated,
- %s : a file suffix appropriate in the context (.txt, .iso or the like)
- %v : the bootcd version string (e.g. 4.0)
- %p : the PLC name
+ - %f : the nodefamily
+ - %a : arch
With the file-based return mechanism, the method returns the full pathname
of the result file;
** WARNING **
- 'partition' - for USB actions only
- 'cramfs'
