The /root directory on CentOS 6 has permissions 0550 but on Debian 7 it is 0700. The Filesystem Hierarchy Standard (FHS) tells about directory organization but remains silent about permissions. Do distributions aspire to be compatible to any standard or it is mostly a matter of following tradition?EDIT 2. Further, /usr/local on CentOS has permissions 0755 while on Debian it is 2775. My hope is that the good folks here might be able to tell (or point to a document) about common practices along with justifications. The FHS would have been the right place but alas it does not say anything about permissions.
Is there any standard on the permissions for system directories?
