Lenny general freeze ahead
at last minute I was incorporating some changes from the version 1,132 and an
error was strained in the script live-helpers

> Jordi Pujol
> live-initramfs (1.132.1-1-jp1) experimental; urgency=medium
> * This package is developed assuming that Busybox is the main command
> shell in the initial ram disk, and the Busybox commands are not overwritten
> by other
> executable files.
> Is developed a patch to initramfs-tools implementing that.
> * File /etc/live.conf stores initial config to start the live OS.
> * File /etc/live.vars is updated with variable values for the live
> The function "really-export" manages this file.
> That values are used in all the live scripts, and also in some scripts
> into the already started Live OS.
> * File /etc/default/live-initramfs has the config to control how is
> generated the initrd.
> * /etc/live.conf: Sets the Live configuration and also
> gets the value of the "conf" option from the boot command line.
> When the variables are assigned in /etc/live.conf, some special
> characters and
> spaces are supported.
> * /debian/init: use the variable values from live.vars.
> * /debian/control: recommends linuxlogo and dialog. Don't recommend
> * /hooks/live: use the file /etc/default/live-initramfs to get the
> options to
> generate the initial RAM disk, and generate it according to that
> values. * /hooks/live: the dependency of the module squashfs to lzma, is
> automatically detected
> by initramfs-tools, (if squashfs is lzma enabled).
> * /hooks/live: use cryptoloop module for encryption, (module from
> kernel). * /hooks/live: include module uloop to cache in RAM memory all the
> reads from the main compressed file, and my custom program ulobdev.
> * /manpages/live-initramfs.en.7.txt: structured in sections,
> explains a lot of new options.
> * /Makefile: installs also the new created files,
> (/etc/default/live-initramfs, and others).
> * scripts/live: Don't change the PATH variable, the default PATH is
> correct. (that default is /sbin:/usr/sbin:/bin:/usr/bin).
> * scripts/live: Parse the boot options according two option types:
> indicators and values.
> Indicators support affirmative and negative forms. Values can be
> an assigment to null value or strings without spaces nor special
> * Use the debug file /tmp/initramfs.debug. Is created a link named
> /live.log, for compatibility with previous versions of live-initramfs.
> * Use the variable VALID_FILESYSTEMS to search for the Live OS related
> * Use the function get_sysblock to get the list of working block devices.
> * Indicator options: scancdrom and scanfloppy, corresponding to the
> SCANCDROM and SCANFLOPPY.
> * When a value refers to a disk partition or block device, use a device
> name or
> a partition property, *LABEL* or either *UUID*. Sometimes specify only
> a name
> to be interpreted as a volume label.
> * Fstab: Use the /etc/fstab file in the root filesystem to mount and
> auto-fsck the persistent
> home partition.
> * Custom mounts: Use the /etc/fstab file in the root filesystem to custom
> mount and also auto-fsck
> other partitions.
> * Parametrized use of swap partitions: none, auto scanning or specifying
> partition device names,
> label or uuid. Multiple swap partitions allowed.
> * Create system files at boot time: To set some little (and very
> important) aspects of the Live OS.
> * Create initrd files at boot time: To set some little (and very
> important) aspects of the Live OS, before beggining to start.
> * Set every aspect of OS persistence: No persistent at all, home
> persistent, home snapshots,
> root persistent, root snapshots. The values of that variables use
> device names, labels
> or uuids. When only a name is found, it's interpreted as a device label
> (for compatibility).
> * Auto update the compressed files containing the Live OS: When the files
> are on a local disk,
> and is found a file with the extension .new replace the old file by the
> new one.
> * append-hostimages: search from the *LIVE_MEDIA_PATH* in subdirectories
> named as
> the *MAC network addresses* or *hostname* or the *active IP adressess*
> for files containing a live filesystem and append them to the live
> * uloop: cache the compressed files of the Live OS. Is created a cache
> in a RAM tmpfs filesystem.
> It has some kind of failure recover, if it did not find something
> usable, the normal loop
> mounting for block devices is performed.
> Experimental: If a label or uuid is specified, *live-initramfs* will
> try to find
> this device for the uloop cache, creating the specified directory, if
> it not exists.
> * networking ip: Specify also the domain name and the nameservers of the
> * user-uid, user-password-crypted, user-default-groups: Specify the
> values for that.
> Optional parameters, if not specified the default values are used.
> * user password disabled : special management of the variables that
> disables the user password.
> * set multiple users in a started Live OS: similar options to the
> previous for an user,
> but multiple users can be specified.
> * home-setup: Indicator to create (or not) initial configuration files in
> the home directory.
> * sudo: Used as an indicator and also extended using as a value, see
> * load-modules: modules to load at kernel start.
> * modprobe-d: modules related instructions: options, install, blacklist
> * fasthalt: For a fast system halt, use this parameter, and the halt
> procedures will unmount only the filesystems mounted with read/write
> option and
> swap partitions also.
> * linuxlogo: Splash the linux logo in the boot text console, also use as
> user prompt in the
> console login, or Splash the linux logo in the halt (or reboot) text
> (see the package linuxlogo)
> * dialog: Text screens with windowing aspect, to request passwords,
> etc... * concurrency: System services startup Concurrency type.
> * multiple locales: as it says.
> * Do package install: a compressed file can contain a directory with
> scripts to install himself.
> If enabled, live-initramfs runs the scripts to install the package.
> (advanced use, take with care)
> I'am referring to custom-made scripts performing some custom tasks,
> (normally live-initramfs can't use
> the control files from a Debian package, and some tasks are not
> practical to do at start time).
> * incremental joining to the aufs root: Every compressed file is added
> separatedly to the
> aufs root; thus giving control to the files that are present in every
> mounting of a compressed file,
> and allows detailed package install.
> * and a lot of other changes, compare with the previous standard version.
