Linux installer fails if there is a tape drive

[Andy]

Hi,

Linux installer (install.sh script) assumes that there is no tape drive on the host system. When there is one, root account typically has $TAPE defined: bash-3.1# echo $TAPE /dev/tape

This is where tar is looking by default. For some reason, installer does not use `-f' (which it should, to avoid ambiquity), when trying to untar itself, and the result is the following error:

bash-3.1# sh VirtualBox-1.6.2-Linux_x86.run Verifying archive integrity... All good. Uncompressing VirtualBox for Linux installation........ VirtualBox Version 1.6.2 (Sat May 31 04:03:49 CEST 2008) installation Removing previous installation of VirtualBox 1.6.0 from /opt/VirtualBox-1.6.0 Installing VirtualBox to /opt/VirtualBox-1.6.2 tar: /dev/tape: Cannot open: No such file or directory tar: Error is not recoverable: exiting now Error installing VirtualBox. Installation aborted

Easy (and ugly) fix would be to add one line at the beginning of the script:

[ -z $TAPE ]

unset TAPE

Proper fix would be the one below:

bash-3.1# diff install.sh install.sh.fixed 261c261 < bzip2 -d -c VirtualBox.tar.bz2 | tar -t > $CONFIG_DIR/$CONFIG_FILES ---

bzip2 -d -c VirtualBox.tar.bz2 | tar -tf - > $CONFIG_DIR/$CONFIG_FILES
