SSHFS and AutoFS

Mounting an SSH-accessible remote directory automatically is a nifty capability. Here's a nice description of how one can do that - specifically under Ubuntu but it will work the same just fine under most other Linux distributions:

Automatically mounting a remote directory in Ubuntu using autofs + sshfs

One thing not mentioned there - and something I keep forgetting about between the instances I need to recall it - is that the passwordless SSH login will fail unless the user directory on the SSH server is writable by the owner only! So, using the same terms as in the example above one should do the following:

1) Log into example.com as remoteusername

2) Execute the following command:
chmod g-w,o-w ~
