To generate an hdd image, binary_hdd first estimates the needed size of
the image using du. By default, when du finds multiple hardlinked copies
of a file, it counts them only once. However, when the target filesystem
is FAT, which does not support hardlinks, these files will take up more
space when finally copying the contents, breaking the build:
P: Copying binary contents into image...
cp: error writing 'chroot/binary.tmp/live/initrd.img-4.9.0-3-amd64': No space left on device
cp: error writing 'chroot/binary.tmp/efi/boot/bootx64.efi': No space left on device
cp: error writing 'chroot/binary.tmp/efi/boot/bootia32.efi': No space left on device
cp: cannot create directory 'chroot/binary.tmp/boot/grub': No space left on device
cp: cannot create directory 'chroot/binary.tmp/isolinux': No space left on device
To fix this, pass --count-links to du when the target is FAT, to make
the space estimation correct.
This problem is exposed by commit 9c974b26b (Instead of renaming kernel
for syslinux, create hardlinks), which might need to be separately fixed
(to not waste space on FAT targets), but binary_hdd should at least
handle hardlinks more gracefully.

Since commit fdc9250bc (Changing package dependency checks within chroot
to work outside as well), Check_package automatically checks for
LB_BUILD_WITH_CHROOT and works inside as well as outside of the chroot,
so no need to check LB_BUILD_WITH_CHROOT before calling them.
Install_package and Remove_package are just a no-op when building
without chroot, so they can also be called unconditionally.
Restore_cache and Save_cache do not check LB_BUILD_WITH_CHROOT but it
it should not hurt to call them when not needed (which already happened
in some cases).
This commit makes all Check_package calls unconditional on
LB_BUILD_WITH_CHROOT.
For binary_syslinux, this fixes the check (which used outdated paths
outside the chroot since 7b6dfd9d1), for binary_grub-efi,
binary_package-lists and chroot_package-lists this simplifies the code
(but also causes the check to become package-based instead of file-based
on apt-based systems), and for binary_loadlin and binary_win32-loader
this adds the check outside the chroot which was previously missing.

Commit e24e4b in debootstrap fixed setup_available to work in the
--foreign case (iotw at the second stage). Unfortunately this breaks
things if components aren't passed to the second stage _and_ your main
component isn't called main.
To fix this, pass --components to both the first and second stage
debootstrap when needed.

Up to now we created a temporary GPG key that we registered with apt-key
but with the switch to GnuPG 2 by default, this code broke. Now we stop
doing that but we add the “trusted=yes“ attribute in sources.list so
that APT knows that the repository can be trusted even if it's unsigned.

This work is based on debian-cd team work and uses,
as much as possible, the same mkisofs options
than the Debian Installation CD disk does.
It assumes that /boot/grub/grub.cfg (and other design items)
is generated by: binary_loopback_cfg .
It relies on efi-image and grub-cpmodules being setup
as build scripts on live-build package.
In the future event of these two files being moved
to a binary package (they are originally from:
src: live-installer) the binary_grub-efi script would have
to be rewritten to take the new paths into account.

additional eltorito entry if we have more than one bootloader.
|
|
These two scripts simplify the creation of efi images based on grub-efi.
I have decided to simply steal them. If I had to include them thanks to a source package that would have mean that an src repo would have to be defined by default.
TODO: Ask in a bug a RFE so that these two scripts are put into a binary that could be consumed by both live-installer and live-build packages.

The binary parts of grub-pc are left for the original binary_grub-pc.
As a consequence both /boot/grub/grub.cfg and /boot/grub/loopback.cfg files will be present in any Debian Live CD.
This might be useful to be reused from binary_grub-* bootloaders.

* Added: functions/bootloaders.sh . This file adds bootloader functions that are heavily used in efi scenarios where a bootloader can act as a first or an extra bootloader.
Since the introduction of the new switch:
--bootloaders
you can setup it like this:
--bootloaders=syslinux,grub-efi
.
This means that syslinux is the first bootloader and grub-efi is the extra bootloader.
* Added new bootloader functions: Check_Non_First_Bootloader and Check_Non_Extra_Bootloader.
These functions let each one of the bootloaders abort the build because
they cannot perform a role either as a first bootloader or as an extra bootloader.
* Added bootloader functions: Check_First_Bootloader_Role, Check_Extra_Bootloader_Role and Check_Any_Bootloader_Role
These functions let bootloaders to force their default role in a single line.
At the same time many binary bootloaders were rewritten to make use of the new bootloader role functions explained above.
These roles were enforced:
binary_grub-legacy : First bootloader
binary_grub-pc : Either first or extra bootloader
binary_syslinux : Either first or extra bootloader
If a bootloader is tried to be used in a role that it's not meant to be used then the build fails because that might lead to a non-bootable system.

Fix #773833

This reverts commit 5161dcdf3bb50a8be7385f86fdfc60b0eb700bfa.
|
|
The fix in a294a46fb9fe28e43686b18da7b22ec1c46b0d4f was not enough.
This should finally resolve the problem when a package list ends
up empty (most notably due to #if evaluating to false).

Some BIOSes dont't boot from partitions starting at sector 1024.
Some are even more peculiar and only start from sector 63.
This patch adds an option for the binary_hdd target to manually
configure the partition start.

"ln -s /bin/true chroot/usr/sbin/flash-kernel" fails if the target
already exists.

Development details
--------------------
* This patch has been based originally on: binary_grub2 . It has been
improved thanks to some binary_syslinux bits.
* This patch ensures that binary_loopback_cfg needs is run
before binary_syslinux is run.
The reason is that it reuses some code from binary_syslinux to avoid
problems when binary_syslinux renames the kernel filenames.
* This patch already supports CPU detection
* I haven't tested all the possible scenarios for the script (with the
latest version). When amd64 and 486 Gnu/Linux flavours is used and the
bootloader is syslinux it works ok.
* I have not implemented a disable switch for not generating it.
Usually you always want loopback.cfg to be there.
* Compared to binary_grub2 script I have removed the installation
entries because I did not see any of them in binary_syslinux.
How to test
-----------
These are some steps to easily test if Looback cfg support is working ok.
0) We assume you have generated an iso
1) Make sure you have a partition that Grub understands. Plain ext4 or
vfat should do it.
2) Create directory: /boot/boot-isos/
3) Put the iso file into that directory making sure it has an ISO or iso
extension.
4) Setup your computer to boot from cdrom and use: Super Grub2 Disk
2.00s2 (Hybrid version recommended)
5) Choose Boot manually...
6) Choose Bootable ISOs (in /boot- ... )
7) Choose (the detected) GRUB Loopback Config
(hdN,msodsN)/boot/boot-ios/name-of-the.iso
8) You will be presented your loopback.cfg. Choose anyone of the entries
(unless it does not match your cpu architecture of course).
9) You should boot into your Debian Live without problems (thanks to
findiso boot parametre).
If you ever wanted to test from your grub2 installation instead from
Super Grub2 Disk check: http://www.supergrubdisk.org/wiki/Loopback.cfg
for an example.

Note: OLDIFS use makes IFS to be reset to "" instead to it being unset.
Either we need to detect if old IFS was unset to unset it
or we need a proper way of setting it as a local variable.
Even more IFS it's not currently used in
Check_package (which it's called from: binary_hdd).
we should have a clean way of resetting/unsetting IFS when calling Check_package.
The other approach it's to explicitly define IFS with its default value in the
places inside live-build code where we implicitly suppose that it's going to have
its default value.
