--001a11333f64a99707050c02739c Content-Type: text/plain; charset=UTF-8 Hi, What do you think about adding support to var rc script to populate /var from files or command? Attached patch adds three variables: 1. populate_var_mtree_enable Enable/disable populating /var from mtree. Defaults to YES to keep current behavior. 2. populate_var_files Files to be copied to /var (similar to mdconfig_md<X>_files) 3. populate_var_cmd Command to run to populate /var (similar to mdconfig_md<X>_cmd) There is one behavior change. If you set populate_var="YES" with mtree and /usr fails to mount, the script will now exit with error. If there is a use case for a non-empty /var, a separate /usr and still wanting to set populate_var="YES" I can modify the checks. Some examples: Keeping a var.tgz on a read-only root file system and extracting it. /var is tmpfs specified in /etc/fstab or varmfs. populate_var="YES" populate_var_cmd="/usr/bin/tar xfzC /etc/var.tgz /var" (add "mount /usr && " before tar if /usr is a separate file system) Keeping a var source dir on root and copying the files from it. Mtree can be skipped if the source dir contains all the subdirs. populate_var="YES" populate_var_mtree_enable="NO" populate_var_files="/etc/var/*" or populate_var_files="/_var/*" - Guy --001a11333f64a99707050c02739c Content-Type: application/octet-stream;
