Chroot login met fedora core 9
Deze howto beschrijft een chrooted login shell voor fedora core 9.
Opzetten chroot basis omgeving
Het opzetten van een chroot basis omgeving is normaal een hoop kopieer en puzzel werk.
Echter bevat yum een handige --installroot optie om alles op ene automatische en nette manier te doen.
Het enige wat nodig is voor een minimale omgeving is bash en alle dependencys. Deze proberen we als volgt te installeren:
[root@localhost ~]# yum --installroot=/chrootedlogin install bash removing mirrorlist with no valid mirrors: /chrootedlogin/var/cache/yum/fedora/mirrorlist.txt Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again [root@localhost ~]# cp /var/cache/yum/fedora/mirrorlist.txt /chrootedlogin/var/cache/yum/fedora/mirrorlist.txt [root@localhost ~]# yum --installroot=/chrootedlogin install bash fedora | 2.4 kB 00:00 primary.sqlite.bz2 | 6.1 MB 00:09 removing mirrorlist with no valid mirrors: /chrootedlogin/var/cache/yum/updates/mirrorlist.txt Error: Cannot retrieve repository metadata (repomd.xml) for repository: updates. Please verify its path and try again You have new mail in /var/spool/mail/root [root@localhost ~]# cp /var/cache/yum/updates/mirrorlist.txt /chrootedlogin/var/cache/yum/updates/mirrorlist.txt
De files die ontbreken kopieren we van het hoofd systeem, totdat yum het doet. (Dit zijn slechts 2 mirrorlist files)
Hierna gaat het installeren van bash correct:

Nu kunnen we onze chroot omgeving testen:
[root@localhost ~]# chroot /chrootedlogin/ bash-3.2# ls / bin boot chrootedlogin dev etc home lib media mnt opt proc root sbin selinux srv sys tmp usr var
We hebben nu een basis omgeving, waar in principe op ingelogd kan worden.
