| + | ===== initramfs-tools ===== | ||
| + | |||
| + | ==== Fixes: ==== | ||
| + | |||
| + | * You'll notice a strange error message due to an empty $init if the rootfs can't be found. | ||
| + | * (Possible) fix: [[http://grml.org/tmp/initramfs-tools_fix_init.diff|initramfs-tools_fix_init.diff]] | ||
| + | |||
| + | * If you have quiet in your /proc/cmdline you can never reach any debug bootoption anymore. | ||
| + | * Fix: [[http://grml.org/tmp/initramfs-tools_do_be_quiet_if_using_debug.diff|initramfs-tools_do_be_quiet_if_using_debug.diff]] | ||
| + | |||
| + | ===== live-initramfs ===== | ||
| + | |||
| + | ==== Current issues ==== | ||
| + | |||
| + | * unify syntax: 'for ... ; do ...' vs. 'for ... \n do ...'... | ||
| + | |||
| + | * bootoption debug -> no support within live-initramfs yet (even though the manpage states it) | ||
| + | |||
| + | * scripts/live modifies stdout/stderr and no output reaches the terminal -> improve it at least for the case when debug bootoption is being used | ||
| + | |||
| + | * Make sure that "Warning: Not enough free memory (991404k > 1651944k) to copy live media in ram." for bootoption toram works via copying only the squashfs module | ||
| + | |||
| + | * http://grml.org/tmp/live-initramfs_support_nognome_panel_and_export_nofstab.diff | ||
| + | |||
| + | * http://grml.org/tmp/0001-support-new-bootoptions-and-environment-variables.patch | ||
| + | |||
| + | * http://grml.org/tmp/0002-display_install_driver_updates_only_if_it_can_be_executed.diff | ||
| + | |||
| + | * while waiting for the root-fs it tries to mount other block devices: 'mount: Mounting /dev/sda1 on /live/image failed: No such device' -> try to disable this behaviour | ||
| + | |||
| + | * make sure the forensic bootoption mode is possible | ||
