Read permission & NPM imports

Hello, I'm using --allow-read=. to allow a script to read files in the current directory. The script also use NPM imports, because of which it also asks to read /home/{username}/.cache/deno. Can I not need to explicitly allow this path, especially since it will differ depending on operating systems and installation modes ? Thanks

Restart Deno process on crash

Hello, The following Node snippet allows a script to restart on crash :

import {
    spawn
} from 'node:child_process';
process.on(
    'uncaughtException',
    () => {
        process.once(
            'exit',
            () => spawn(
                process.argv.shift(),
                process.argv,
                {
                    cwd: process.cwd(),
                    detached: true,
                    stdio: 'inherit'
                }
            )
        );
        process.exit();
    }
);

import {
    spawn
} from 'node:child_process';
process.on(
    'uncaughtException',
    () => {
        process.once(
            'exit',
            () => spawn(
                process.argv.shift(),
                process.argv,
                {
                    cwd: process.cwd(),
                    detached: true,
                    stdio: 'inherit'
                }
            )
        );
        process.exit();
    }
);

What's its Deno equivalent ? Thanks
