That describes mdev to a T. No need to re-invent the wheel. |

The busybox people would probably not want "additional functionality" |
| 11 |
built-in. A better route would be "mdev helper programs" or "shims" |
| 12 |
that we can add to Gentoo as required. Actually, shell scripts |
| 13 |
launched by /etc/mdev.conf can be quite powerful. E.g. wiki page |
| 14 |
https://wiki.gentoo.org/wiki/Mdev/Automount_USB has ash scripts to |
| 15 |
implement auto(un)mounting of USB devices. It works for me, but I'm |
| 16 |
waiting for feedback from other users before moving it out of beta |
| 17 |
("Work In Progress") status. Once I'm confident in the scripts, I'll |
| 18 |
link to them from the main mdev page at |
| 19 |
https://wiki.gentoo.org/wiki/Mdev In case you're wondering, I'm not a |
| 20 |
C programmer, so scripting was the only available tool for me. |

It would be an interesting project to make a busybox-based Gentoo |
| 27 |
fork. But there are differences between busybox utilities and |
| 28 |
standalone gnu utilities. This is especially important for a |
| 29 |
source-based distro like Gentoo, where all sorts of gnu utilities |
| 30 |
get excercised by build scripts each time you do an update. |
