Thanks. I wouldn't be confused with the above description like before.
I see systems other than Linux listed in os: section; presumably our $HOME would not persist and we wouldn't even have $HOME/travis-cache directory when we run on them, so "mkdir -p" would be both necessary and save to have whether the "cache" feature is available or not. And the "ln -s" would be the same way--either we symlink to a file that hasn't been born (either on a platform without "cache" feature, or the first run on Linux) and that is perfectly fine.
And all the systems listed in os: section supports symlinks, so the "mkdir -p && ln -s" is safe.
Looks sensible. Thanks.
