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.

-- Firstly, remove PRIMARY KEY attribute of former PRIMARY KEY
ALTER TABLE <table_name> DROP CONSTRAINT <table_name>_pkey;

-- Then change column name of  your PRIMARY KEY and PRIMARY KEY candidates properly.
ALTER TABLE <table_name> RENAME COLUMN <primary_key_candidate> TO id;

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

const combine = (...arrays) => [].concat(...arrays);

const compact = arr => arr.filter(Boolean);

const contains = (() => Array.prototype.includes
  ? (arr, value) => arr.includes(value)
  : (arr, value) => arr.some(el => el === value)

const noop = arg => arg;

const combine = () => Array.from(arguments).reduce((a, b) => a.concat(b));

const compact = arr => arr.filter(el => el);

const difference = () => {
  var others = Array.from(arguments).slice(1).reduce((a, b) => a.concat(b));
  return arguments[0].filter(el => !others.some(exclude => el === exclude));
};

Spawning multiple ffmpeg processes with xargs:

On standard NVIDIA GPUs (Not the Quadros and Tesla lines), NVENC encodes are limited to two simultaneous sessions. The sample below illustrates how to pass a list of AVI files to ffmpeg and encode them to HEVC on two encode sessions:

$ find Videos/ -type f -name \*.avi -print | sed 's/.avi$//' |\
  xargs -n 1 -I@ -P 2 ffmpeg -i "@.avi" -c:a aac -c:v hevc_nvenc "@.mp4"

This will find all files with the ending .avi in the directory Videos/ and transcode them into HEVC/H265+AAC files with the ending .mp4. The noteworthy part here is the -P 2 to xargs, which starts up to two processes in parallel.
