17 # it would be nice to use just one tool together with the list of files.
18 # The main problem is that stat does not report the correct file sizes. In
19 # procfs files seem to have a size of 0 while in sysfs they often appear
20 # bigger than they really are.
21 # Archivers like tar/cpio etc. can not be used for procfs and sysfs.
22 # This script first gets a temporary copy of all the files we want. After
23 # copying the files can be archived with tar.
