4.1.1 Singularity architecture
| Strengths | Weaknesses |
|---|---|
| No dependency of a daemon | At the time of writing only good support in Linux Mac experimental. Desktop edition. Only running |
| Can be run as a simple user Avoids permission headaches and hacks |
For some features you need root account (or sudo) |
| Image/container is a file (or directory) | |
| More easily portable | |
| Two types of images: Read-only (production) Writable (development, via sandbox) |
