This code will automatically check for the file on $CDROOT, as well as automatically pick up the casper-rw file created by unetbooting for persistence. Additionally we add the option for aufs=search which will search all drives for livecd.aufs. Possible later enhancements include searching other partitions on the CDROOT_DEV for livecd.aufs automatically instead of needing aufs=search. Then again, possible later enhancements also include just always searching, it's shockingly fast to do the search... defaults/initrd.scripts | 24 ++++++++++++++++++++++-- 1 file changed, 22 insertions(+), 2 deletions(-) diff --git a/defaults/initrd.scripts b/defaults/initrd.scripts index d8142a2..e05809c 100644 --- a/defaults/initrd.scripts +++ b/defaults/initrd.scripts @@ -123,7 +123,7 @@ findmediamount() { fi good_msg "Attempting to mount media: ${x}" ${CRYPT_SILENT} - mount -r -t ${CDROOT_TYPE} ${x} ${mntcddir} >/dev/null 2>&1 + mount -t ${CDROOT_TYPE} ${x} ${mntcddir} >/dev/null 2>&1 if [ "$?" = '0' ] then if [ -n "${ISOBOOT}" ]; then @@ -408,12 +408,29 @@ create_changefs() { setup_aufs() { bootstrapCD + if [ "$aufs_dev" = "search" ]; then + findmediamount "aufs-dev" "$aufs_union_file" \ + "aufs_dev" "$aufs_dev_mnt" $(devicelist) + aufs_mounted="1" + elif [ -z $aufs_dev ] && [ -w "$CDROOT_PATH/$aufs_union_file" ]; then + aufs_dev="$REAL_ROOT" + aufs_dev_mnt="$CDROOT_PATH" + aufs_mounted="1" + fi + if [ -z $aufs_dev ] && [ -w "$CDROOT_PATH/casper-rw" ]; then + aufs_dev="$REAL_ROOT" + aufs_dev_mnt="$CDROOT_PATH" + aufs_union_file="/casper-rw" + aufs_mounted="1" + fi + if [ -n "$aufs_dev" ]; then if [ ! -b $aufs_dev ]; then bad_msg "$aufs_dev is not a valid block device" local invalidblk=1 unset aufs_dev - else + #skip this block when aufs_dev_mnt is already mounted + elif [ "$aufs_mounted" != "1" ]; then good_msg "Mounting $aufs_dev to $aufs_memory for aufs support" if ! mount -t auto "$aufs_dev" "$aufs_dev_mnt" &>/dev/null; then @@ -428,6 +445,9 @@ setup_aufs() { elif [ -n "$aufs_dev" ]; then while :; do if mount -t auto "$aufs_dev_mnt$aufs_union_file" "$aufs_memory" &>/dev/null; then + if [ "$aufs_union_file" = "/casper-rw" ];then + bad_msg "Use of livecd.aufs preferred to casper-rw for changes saving, please rename the file." + fi break else bad_msg "Mounting of changes file failed, Running e2fsck"
