| Code: | root #mkdir -p usr/portage
Mount the required directories:
root #mount --bind /usr/portage usr/portage
root #mount --bind /proc proc
root #mount --bind /sys sys
root #mount --bind /dev dev
root #mount --bind /dev/pts dev/pts
Chroot into the environment: |
This quote from the Embedded Handbook is using the deprecated /usr/portage instead of /var/db/repos/gentoo.
What should it be? |

This is for a chroot build and I thought it was mounting the host so as to not need the tree in the chroot.
I just created the directory and synced it, but that is a kludge, I think.
Eternel noob here.
Thanks. |

| Generically, it should be $PORTDIR. On old systems, that was /usr/portage. On new ones, /var/db/repos/gentoo. Yes, it is mounting the host's filesystems into the chroot. Use the host's $PORTDIR on the left side and the chroot's $PORTDIR for the mkdir and the right side. Note that the chroot has no leading / in this section. |

Thanks, Hu.
Something that eludes me is a comprehensive understanding of the system variables, what's needed, what's declared, etc.. I have looked and if there is some written guide to help me, I have not recognized it.
As one of many examples, shouldn't there be a way of seeing what is declared as PORTDIR? |

flysideways,
Its all set by your selected profile. Profiles are cascading. Unravelling one will make your head hurt.
