# Thomas:
|
|
# xorriso provides built-in means for comparison:
|
|
# -compare_r disk_path iso_rr_path
|
|
# Possibly i will have to enhance it so that it is suitable for automatic
|
|
# testing. (I used it mainly for testing -update_r.)
|
|
|
|
# xorriso could use
|
|
# -osirrox on -extract iso_rr_path disk_path
|
|
# to pull a tree out of the image without mounting it.
|
|
|
|
# One could mount the image -o loop. (Needs superuser authority.)
|
|
|
|
# There is a program test/compare_file which acts on a mounted image
|
|
# or on extracted trees i.e. completely independent of xorriso code.
|
|
# See libisoburn/README paragraph "Testing".
|
|
# With extracted trees one will want to use option -no_ctime.
|
|
|
|
# One may use command diff -r to compare directory trees of a mounted image
|
|
# or extracted trees.
|

# George:
|
|
# xorriso -indev my.iso -find / vs. find input_dir
|
|
# bsdtar -xf my.iso vs. input_dir
