Vim is scriptable with TCL: https://vimhelp.org/if_tcl.txt.html

http://mlmmj.org/ claims to be heavily inspired by ezmlm. I haven't used either so I don't know how well it works as a replacement, but it might be worth a look.

That sounds a bit like what Joyent is doing in their Autopilot Pattern implementation for MySQL: https://www.joyent.com/blog/dbaas-simplicity-no-lock-in

I'm used to that from rsync. I find it quite handy.

There's also git-spindle for this:

What gave you that impression? With `zpool attach` you can attach a device to an existing VDEV (single device, mirror, RAIDZ) to increase redundancy. With `zpool add` you can add a new VDEV to your pool to extend its capacity.

See https://illumos.org/man/1m/zpool
