Cask-Upgrade

Small utility to help you manage packages installed via Homebrew Cask as it currently can't upgrade installed packages for you or clean up old versions.

The script will ask you if you want to upgrade applications which has newer versions available. Downloads from previous versions of applications will be removed when an application is updated, like what Homebrew has been doing since version 2.0.0. This behaviour can be disabled by setting the environment variable HOMEBREW_NO_INSTALL_CLEANUP.

Installation

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

So, to get something like /etc/rc.local you can use the custom SMF import facility. (See the source for more information about how this actually works.)

/opt is mounted out of zones/opt by default. You can create a directory /opt/custom/smf and populate it with SMF manifests. Any manifests you put in there will be imported by SmartOS when it boots. Below is an example SMF manifest that simply starts /opt/custom/bin/postboot, a self-explanatory shell script that you can use like /etc/rc.local.

Note that it would likely be better to customise and respin your own images, as putting a bunch of platform state in the zones pool undoes some of the benefits of the ramdisk platform architecture that SmartOS has.

	'Twas the night before Christmas, when all through the racks
	Not a server was alerting, not even Compaqs.
	The backups were written to tapes with care
	In hopes that later the data would be there.

	The machines were nestled all snug in their sleds
	Whilst visions of vengeance danced in their heads;
	And oncall in his three-wolf and I in my rack.
	Had just settled down for some syn and some ack.
