- Can be used to save/copy files before and after the installation.
- During the jumpstart, filesystems being installed are mounted
on
/a, so be careful with this! - During pre-install, the
/afilesystem must be explicitly mounted. - Use the variable $SI_CONFIG_DIR to copy files from the
jumpstart configuration directory to the client:
cp ${SI_CONFIG_DIR}/file /a/fileA listing of installation environment variables can be found in Table 7-1 of the Advanced Installation Guide. - Can use the pre-install script to save
files (to
/tmp) during the install process and restore them with the post-install script.
