I've got some minimalized Gentoo servers, 586 vintage, still running |
| 15 |
on the original SD cards. I used "quality" cards, vintage 2006. The |
| 16 |
trick I found was to run the -Os small kernel and keep everything in ram, |
| 17 |
if that is possible. Also use ext2 file system, as it is better on |
| 18 |
minimal hardware. NFS mount busy stuff to other drives across the net. |

ROCK Solid..... as minimalized gentoo servers on SD for a 8 years now. |
| 21 |
If you build on Rpi, it's at least a minimal system, or it can be set |
| 22 |
up as a pure embedded system: |

If you got the time to LEARN, gentoo as an embedded system if far |
| 57 |
superior than a gentoo minimalized server, such as the above dinosaur. |

You need to be *reasonable* with what you ask your Rpi to do; imho. |

ps, be nice to Neil, Alan and the other old farts on this list, as we |
| 62 |
all have very old toys we rarely talk about...... I.E. nothing new |
| 63 |
in *nix, it's all just colorful and recycled, imho. |
