# sometimes, when changing permission or ownership you run a command like
# chown -R www-data: .*
# and it does what you want correctly: change ownership on dotfiles
# but it does also what you don't want: change ownership on all files which are in the parent directory
# which is really bad

# the solution, taken from http://sysadminnotebook.blogspot.fr/2012/06/how-to-reset-folder-permissions-to.html

# 1. on a snapshot or another Debian installation run
find / -exec stat --format "chmod %a %n" {} \; > /tmp/restoreperms.sh
