# For security reasons, many CryptoNAS scripts will refuse

# to run if their parent directories have unsafe permissions.
|

# The files in config/chroot_local-includes are, by default,
|
|
# owned by the user who did the SVN checkout. Therefore
|
|
# reset the important directories there to being owned by root.
|
|
# Debian Policy specifies that local users and package-created
|
|
# users have different uid ranges, so the set of files with
|
|
# unrecognized uid's should be the same as the set of files added
|
|
# by "config/chroot_local-includes/".
|
|
# Note that we are doing this at build time, not run time!
|
|
# Only fix files that are neither setuid nor setgid:
