Common File permissions.

I logged in as non-root I found I couldn't execute any commands (but that's not the topic of this post). I now realize the necessity of running chown on my filesystem but am having trouble deciding what permissions (read, write, and execute) are necessary for what groups (root, user, and world). Also are there any directories that warrant separate configuration schemes (hence you can't set the same permissions for the whole file system). If so then what they?

It would help if I knew the minimal configuration necessary for a typical desktop gentoo installation, and what is the most practical.

Posting your own permission setup (such as chown xxx /usr) along with your reasoning behind it would also be of interest.

its a complex web... step 1 know your $PATH, step 2 get a sane umask, step 3 learn very well chown / users / groups.... id leave the system as is for now... see what the path is, etc. umask thats common is 0022 (shown by running umask)

common paths are for root /bin, /sbin, /usr/bin, /usr/sbin
common paths for users are /bin, /usr/bin

sometimes systems have /usr/local/bin & /usr/local/sbin & /opt/bin... its where it looks for programs, if i run "chown" it is in the path, /bin/chown if its not in the path it requires ./ (if your in its current directory, ie /opt/bin)
