I always adjust the Model for the data base I am setting up, particular file locations, and I like to increase the starting size of files to at least 100 mb

I typically made the following changes:

1. Change the file growth settings from percentages to fixed growths of 512MB (or 1GB depending on what the server is used for - and turn on IFI at the OS-level)

2. Set a fixed starting size for the default data and log files

2. Ensure the page verification is set to CHECKSUM

The rest of the defaults seem good enough to me (for what I've always needed :-D)

Yes, I almost always adjust the model db as well. Just like MyDoggieJessie does.

Never touched the model before, myself. But after reading that blog, I am seriously considering adding a tally table to it whenever possible.

I adjust file locations, growth, and starting size. On development servers, I change the recovery model to SIMPLE. I also add a series of objects to model, mostly database-specific metadata queries like table valued functions to identify certificate-signed objects or role membership chains, etc.

As part of all instance installs I change the default initial size and growth settings to protect against lazy database creations by people or application installers.

I always change the model recovery model to SIMPLE for development and QA instances since the recovery plan is to restore from the latest FULL and DIFFERENTIAL backup.

Where there are utility procs such as those used to test for absent clustered indexes, primary keys, use of reserved words etc it makes sense to install these in the model database as any new database will automatically gain these objects.

Yes, years ago when I was doing more DBA type work, I would adjust the model.

The more you are prepared, the less you need it.

I absolutely change the model DB when setting up a new SQL instance. The most grievous problem I find on instances set up by obviously "reluctant" non-DBAs is with file growth, leaving it to the default 10% (which is VERY bad for new, smaller DB's especially, as this forces many unnecessary and very expensive growth operations). I change this to a set size (1GB data, 512MB log) and depending on the instance cap it, or don't. The recovery will change depending on the environment (e.g., full logging for production, simple for development). Finally, I'll modify the auto update stats (Y) and async update options (Y).

Depends on the instance. Environments where one or more dbs are created for each customer, for example, I'll adjust model so that it works well for the application(s) involved. Sometimes I'll use a script after the db is created.

I'll usually change file locations, the recovery model gets set to Simple in the event someone creates a new db while I'm away and they don't know enough to do txn log backups and file growth gets set to a size rather than pct.

I modify the initial size, autogrowth, and switch the recovery model to SIMPLE for dev/test/QA environments.

After each SQL install I run a script to change numerous setting and setup the environment before and data touches the instance. With model database I set initial size, autogrowth, and set recovery model to SIMPLE.
