I wouldn't worry about that at all. |

Gentoo infra is vastly more resilient than that, and there are several |
42 |
official hosts in some sort of cluster arrangement. I have minimally 4 |
43 |
gentoo hosts here at home and many many times I've run --sync |
44 |
simultaneously on all of them 5-10 times a day, with not a peep out of |
45 |
infra. I don't do this deliberately, sometimes I forget just how |
46 |
powerful clusterssh can be :-) |

|
48 |
Plus our ftp server at work is a mirror for all of ZA with no special |
49 |
permissions, it syncs every hour. |

51 |
The message in --sync is, I believe, a holdover from long long ago that |
52 |
hasn't been valid for years. But it's left to discourage abuse. What you |
53 |
are doing is not abuse, it's normal activity. Many of us here have |
54 |
multiple gentoo installs. |
55 |
|
56 |
If you want to reduce the data downloaded, then by all means configure |
57 |
rsyncd to share the tree on the PC, and point the ARM to that. Don't |
58 |
worry about overlays, the amount of changed data from them is usually |
59 |
too small to worry about. |
