link gitconfig and ssh to `.sail/Dockerfile` via a share

[Teddy]

Is this something that we should do via a share just to make working with the repo easier?

Edit:
It is documented here: https://sail.dev/docs/concepts/labels/ as a recommendation, but is this something that we want?

Not sure what you mean exactly.

.gitconfig and .ssh is already shared into the container by ubuntu-dev.

[Teddy]

Hm, then maybe we should update the docs to note that both of them are auto?

[Teddy]

Also, I am not sure that you understood what I meant..

happens when I try to commit from inside the current sail instance.

[Ammar Bandukwala]

Ahh, I think the .gitconfig share was removed at some point.

I think we can add it here

https://github.com/cdr/sail/blob/master/images/ubuntu-dev/Dockerfile#L1-L4

Any objections @nathanpotter ?

[Nathan Potter]

If the ~/.gitconfig mount source doesn't exist, sail will create it as a directory by default. I think that's why we decided to keep it out of the ubuntu-dev image

[Nathan Potter]

I know we discussed for a bit with @nhooyr what we should do when a mount source doesn't exist, but I don't think creating the dir makes sense for a scenario like this.

Should we just log an error and not mount it in if it doesn't exist instead of creating it as a dir?

[Teddy]

how would I go about mounting it without maintaining my own fork?

[Teddy]

Realized that hats will do this for us.
