angular-cli build with --watch doesn't watch

I faced a problem, on Ubuntu 17.04 @angular/[email protected] command ng build --watch exits after it builds app (successfully) and doesn't start to watch. ng serve though works fine and starts watcher.

The most similar problems I found were solved with setting output path via -op option or outDir property in .angular-cli.json, none of these seem to help in my case. Any ideas of what possibly can be the reason to that?

Update

My bad, ng serve just didn't stop process, watcher still wasn't working.

Given the update, it became clear that the problem is with watching generally and not with specific command so I found out that the problem is with Linux Inotify watches limit which can be expanded in either way:

sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p --system

or

echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches

The problem with this is that limit resets on computer restart.
