Schlagwort: administration

In der chroot-Umgebung aus der ersten Anleitung kann auch direkt ein rpm Paket erstellen, welches eine saubere Installation der aktualisierten Bash ermöglicht.

Die Anleitung beginnt an Punkt 2 (2. Bash Quellen bereitstellen) der ersten Anleitung!

In der chroot-Umgebung des Build Systems einen Benutzer für den Paketbau anlegen:

chroot /mnt/chroot
adduser builder  && su builder && cd ~

Im Anschluß werden die für rpmbuild notwendigen Verzeichnisse, die drei Bash Konfigurations-Dateien .bashrc, .bash_profile, .bash_logout und die Specs-Datei für den rpm-Paketbau angelegt und die Bash Quellcodes sowie Patches heruntergeaden.:

%description
The GNU Bourne Again shell (Bash) is a shell or command language
interpreter that is compatible with the Bourne shell (sh). Bash
incorporates useful features from the Korn shell (ksh) and the C shell
(csh). Most sh scripts can be run by bash without modification.

Die bash.spec-Datei enthält die Konfigutarion des Paketes sowie die bei der Installation und deinstallation notwendigen Scripte. Die Vorliegende SPECS Datei ist eine bearbeitung der Original Quelle von Fedora Core 12, welche ich für die aktuelle BASH angepasst habe.

Jetzt kann mit rpmbuild das Paket erstellt werden, welches direkt im Anschluss mit rpm Installiert werden kann. Das alte Bash Paket wird hierbei durch das neue Paket ersetzt.

rpmbuild -ba  bash.spec
rpm -U --force --replacefiles /mnt/chroot/home/builder/rpmbuild/RPMS/armv6l/bash-4.3.30-1.fc12.armv6l.rpm
