Is there any compelling reason for not using tarball-2018.02.26? |
| 15 |
|
| 16 |
Snapdragon 625 in Redmi Note 4 is 64bit. Is the linux kernel on it |
| 17 |
64bit? If so, you will also be able to install a 64bit Gentoo tarball. |

Thanks, they look well indeed. |

Yes, that's expected. |

No, the root directory does not change. That is for chroot[1] or linux |
| 37 |
containers or filesystem namespaces[3]. Gentoo Prefix runs from within |
| 38 |
a directory prefix.[4] In our case, it is /data/gentoo. |

Well, we don't have control over the filesystem layout by Gentoo Prefix |
| 45 |
on an Android device. It is Android init system that takes care of |
| 46 |
/proc, /sys, /dev, etc. This might change when the control is |
| 47 |
transferred from Android to Gentoo in the future. |

Did it build successfully? |

Nice! As a proof of concept, could you please write an ebuild for the |
| 62 |
linux kernel of Samsung Galaxy Grand 2? |
| 63 |
|
| 64 |

|
| 66 |
How about a kernel ebuild as above? |
| 67 |
|
| 68 |
Please start drafting your application if you intend to get involved. |
| 69 |
And circulate on this mailing list for discussion. |
