Any kernel modules mentioned here will be added to the modprobe blacklist.
This will help out people who need to blacklist the nouveau driver,
for instance if they have a too-new computer.
Syntax:
blacklist=mod1[,mod2[,...]]

Only relevant if the user added the 'toram' boot option.
|
|
This gets rid of quite some code duplication.

This allows the user to remove the bootable Live media afterwards, because
the complete OS will been copied to RAM and run from there when adding
the boot commandline parameter 'toram'.
This feature works nicely for the XFCE ISO since that one is fairly small.
Untested for the bigger ISOs; you need more patience while the squashfs
modules are being copied to RAM, and available RAM decreases a lot.
Realistically speaking, your computer would need 1 or 2 GB of RAM for
the XFCE variant, 2 or 4 GB RAM for the Mate variant, and 4 to 8 GB RAM
for the KDE4 and Plasma5 variants.

This adds an option to store persistent data in a container file instead of
a directory in the USB stick's Linux filesystem.
Theoretically, this would allow the Slackware Live files to be copied to
a VFAT partition on a stick without erasing it, as long as the stick is
made bootable and the Live kernel & initrd are added to the boot menu.
To create a USB stick from the Live ISO which uses a persistence file instead
of a persistence directory, run the 'iso2usb.sh' script with a new parameter:
-P|--persistfile Use a 'persistence' container file instead of
a directory (for use on FAT filesystem).
The following example creates a 750 MB LUKS-encrypted container file
'slhome.img' which will contain /home ; as well as a file '/persistence.img'
in the root of the USB's Linux partition which will be used to store the
Live OS' persistent data:
./iso2usb.sh -i slackware64-live-current.iso -o /dev/sdX -c 750M -P
NOTE:
The persistence container file will be created as a 'sparse' file which
starts as an empty file not using up any disk space, but is allowed to
grow dynamically to consume a maximum value of 90% of the free disk space
on the Linux partition of the USB stick.

The mkinitrd script adds /lib/udev/rules.d/60-openobex.rules to the initrd
image, but since the rest of the openobex package is not added, this results
in a "error: obex-check-device not found".
We do not need bluetooth stuff in the initrd anyway, so we remove the rules
file manually from the initrd until mkinitrd gets fixed.
|

The /home would end up read-only if the "nop" parameter was passed
on the boot commandline in order to disable persistence for the session.
So, remount the media as writable earlier during init.

Milestone reached:
- add LUKS-encrypted /home/.
|
|
Using iso2usb.sh script's new '-c' parameter, you can define the size for
a container file in the root of the USB stick's Linux partition.
- The container file will be loop-mounted and LUKS-encrypted and the
Live OS will mount the filesystem inside the container on /home/.
- The LUKS passphrase will be defined when executing the 'iso2usb.sh' script.
- The original /home content of the ISO will be copied into the
LUKS-encrypted container during execution of the 'iso2usb.sh' script.
- If for whatever reason you do not want to unlock & mount the LUKS container
during boot, you must add the boot parameter " luksvol= " to the syslinux
or grub commandline.

The new kernel has version number '4.4.0'. Yet the kernel package names,
like the kernel source tarball, has a version '4.4'. We need to compensate.

Slackware has added PulseAudio plus a /etc/asound.conf file,
which configures all ALSA output as an input to PA.
An ALSA softvol pre-amp is therefore no longer needed and our Live script
should not overwrite the /etc/asound.conf file in the OS.
|
|
|
|
Reason: okular is still KDE4 based but libkexiv2 moved on and is now KF5 based.
|
|
Roadmap:
v0.3.9: adding LUKS encrypted /home
v0.4 (Beta4): LUKS home setup stable enough for public consumption.
|
|
|
|
PulseAudio and its dependencies mainly.

The customized ISOs (Slackware plus 3rd party software) can include the
proprietary drivers, but the Full Slackware ISO is meant as a demo for
official Slackware and therefore should not include 3rd party packages.
If you respin the SLACKWARE ISO, it is of course still possible to add the
binary Nvidia blob yourself by copying the graphics/*nvidia*.szx file to
the 'optional' directory yourself. Nothing else is needed, it will 'just' work.

- generate the grub fonts (.pf2) ourselves instead of using the
Slackware-provided grub font file.
- expand the help text about the boot parameters.
- show the liveslak version number in the boot menu.
- remove the 'boot any OS' menu item in Grub because it never worked for me.
- add a bit of Grub help text at the bottom of the screen.
NOTES:
- I do not like the way how I had to implement the Grub2 help menu,
it is ugly. Perhaps the text artefacts and understrikes are caused by the
fact that the grub console has to paint on top of the graphical boot menu?
- In any case, the grub console (the black rectangle in the middle) has its
coordinates hard-coded in the grub2 source so it is not configurable.
- the grub fonts look better than in Beta3 but I am still not happy with them.

New parameter for the boot commandline:
xkb=[language],variant
Examples:
# Only specify a Xkbvariant, and inherit the console keyboard layout in X:
kbd=nl xkb=,sundeadkeys
# Define a 'french swiss' layout in X, independent of the console:
xkb=ch,fr
Two new keyboard/language choices have been added which use this functionality:
- german swiss
- french swiss
(requested by Niki Kovacs).
New: if a non-US keyboard layout is selected, the US layout will be added
as a secondary layout. Toggling between the two layouts is possible using
the Shift-LeftAlt key combo.
Also new: the RightAlt key is now defined as the Compose Key in X. Meaning,
the combo <RightAlt><"><e> will generate a 'ë character'.

This modifies Didier's original patch with a simpler set of parameters.
His recommendations are based on these threads:
http://www.syslinux.org/archives/2015-February/023256.html
http://www.syslinux.org/archives/2015-May/023455.html
http://www.syslinux.org/archives/2014-July/022538.html
The new parameters allow the big ISOs to be booted in VBox.
Patch proposed by Didier Spaier.

Slackware's shipped Grub font is 19 point in size which does not scale well.

Two new parameters '--force' and '--persistence'. Read "usb2iso.sh --help".
Size of the EFI partition was reduced from 200 to 100 MB.
The wait-for-root time in the initrd.img file is changed for both BIOS
and UEFI boot; this should make boot work out of the box for most computers.
More robustness was added in handling race conditions.
Only make the USB stick UEFI-bootable if the ISO file is capable of the same.
|
|
The GRUB2 theme is similar to the Syslinux theme used for BIOS boot.
However, the GRUB menu also allows the user to select a timezone,
whereas due to the limitations of syslinux, you'll have to edit the
syslinux commandline to change your timezone there.

However... does not seem to work for non-US language choices.

The computer may have other partitions which contain a Live image,
we need to choose one.
Alternatively, use "livemedia=/dev/sdX" to point init to the Live device
we want to boot.
