| == Using dash as the default POSIX compliant /bin/sh in Funtoo Linux ==
| |
|
| |
|
| * Dash requires less memory and is faster than Bash (so all scripts referencing #!/bin/sh will run faster)
| |
| ** In particular, Funtoo Linux systems will boot faster w/Dash than with Bash
| |
| ** Configure scripts will be faster (every little thing counts)
| |
| ** from 'man 3 system':
| |
| system() executes a command specified in command by calling /bin/sh -c command,
| |
| and returns after the command has been completed.
| |
| * Bash called via /bin/sh still supports Bash-isms, which is bad for scripts that are supposed to be portable (portability is a virtue in Funtoo Linux)
| |
| * Dash has fewer dependencies than Bash (sort of cool).

| < ermo > So in that sense, using dash as /bin/sh aligns with one of the original core goals
| |
| for gentoo (and now funtoo) re. 'it would just allow for a leaner faster system'
| |
| < drobbins > ermo: right, it is a logical move for us
| |
| < drobbins > performance is not the main goal, but it is *a* goal
| |
| < drobbins > it is not something to be pursued at the expense of stability, reliability, etc.
