Currently, for no reason we have a different folder structure in the kdump initrd compared to the installed package. Change it here, so both directories' structure match now. We also changed the copy command for the config files, removing some unnecessary quotes. Signed-off-by: Guilherme G. Piccoli <gpiccoli@igalia.com>

# The most fail-prone operations are guarded with conditionals to

# a bad condition and get stuck in this minimal initrd with no

# We have a more controlled situation with regards the config
|

# files here, since we manually added them in the initrd and

# the validation also happened there, during such addition,
|
|
# hence not requiring checks here.
