Xubuntu14.04のGentoochrootに/ dev / shmをマウントする
Gentooをインストールしようとしていますが、Gentooが提供する起動可能な最小限のインストールCDのいずれかを使用する代わりに、Ubuntuでchrootを使用しています。私は主にここで概説されている指示に従っています http://www.wikihow.com/Install-Gentoo-Linux-from-Ubunt しかし、必要なときはいつでもこのガイドを参照しています。 https://wiki.gentoo.org/wiki/Handbook:AMD64
ここで、最適なパフォーマンスを得るためにインストールをbootstrapすることにしました。最初の問題が発生した後、「emerge-esystem」を実行することになりました。これを行うと、次のエラーで失敗します。

これがemerge--info '= dev-lang/python-2.7.7 :: gentoo'からの出力です：

私のchroot環境では、次のマウントコマンドを使用します。
Sudo mount /dev/sda4 /mnt/gentoo
Sudo mount -t proc none /mnt/gentoo/proc
Sudo mount --rbind /sys /mnt/gentoo/sys
Sudo mount --rbind /dev /mnt/gentoo/dev
私はUbuntuで自分のカーネルをコンパイルする方法を理解しましたが、それでも私はLinuxの主要な初心者です。実際、私は昨日/ dev/shmについてしか知りませんでした。また、Ubuntuでは、/ dev/shmは単に/ run/shmへのリンクであるため、おそらくそれが私の問題の原因であることも学びました。私は実際に/ run/shmもマウントしようとしましたが、役に立ちません。
/ dev/shmを適切にマウントする方法を誰かが知っているなら、それは素晴らしいことです。
親環境から、mount --bind /dev/shm /mnt/gentoo/dev/shm
または、GentooInfraに使用する呼び出しは次のとおりです。
echo /dev /dev/shm /dev/pts /proc /sys /run |xargs -n1 |xargs -I{} mount -o bind {} /mnt/gentoo/{}
