Previously, you had to specify two parameters MKIMAGE_PREFIX and
GLOBAL_PREFIX with the same value - the path to mkimage. And this
behavior has not been documented. The GLOBAL_PREFIX variable is
defined in mkimage in config.mk and rules.mk.
At the moment, the ability to select the kernel with which to boot is
implemented only for grub (grub-pc, grub-efi, ieee1275boot).
note that renamed STAGE1_KFLAVOUR to STAGE1_KFLAVOURS, as multiple
kernels can now be added.
pauli@ has proposed slightly different setup to what is provided
by livecd-qemu-arch; but the use case might be different either.
At least provide the link to those interested.
The former ("proper 32-bit x86 package form") has been suggested
by zerg@ quite some time ago but the desired interface wasn't clear
at the moment IIRC; a quiet morning helped me realize that
ICAClient-preinstall@IA32
is rather more readable than
ICAClient-preinstall@i586 i586-ICAClient-preinstall@x86_64
so here's the (trivial) implementation; and I actually needed
the latter, @X86 ("any-x86") to mark x86-only packages so
xorg-drv-intel@X86
is now equivalent to
xorg-drv-intel@i586 xorg-drv-intel@x86_64
It's at least removing the very obvious user->root
attack through (maliciously) modifying bin/tar2fs
and waiting for it to be run; if mkimage-profiles
is installed system-wide as a package, the script
from /usr/share/mkimage-profiles will be tried so
those willing to allow vm/* build to themselves
can provide for a passwordless sudo (as described
in doc/vm.txt) to run a root-only writable script,
not user-writable.
Still not perfect but a step away from the abyss.
Merge commits aren't going to be merged upstream
for these break all sorts of git tools including
log -p, blame, bisect, etc (or make their use less
convenient).
Sometimes we tend to "just" translate the code to human
which doesn't really help; what usually helps is noting
down what the code author intended to implement or fix,
and what was the case for that.
The new archdep part has been initially included into
"The Basics" chapter which it doesn't really belong to,
let's move it into Addendum.
NB: I'd better try building a package and skimming over
at least the index upon having modified docs next time.
This is an initial implementation of architecture dependent
contents handling for package lists more or less in the vein
of mkimage-profiles-desktop's one *but* using suffix part to
filter words in or out *not* prefix part to replace it with
a comment marker (thus filtering out lines).
The syntax should be pretty obvious:
a b@i586 c@x86_64
will get "a b" given ARCH=i586 and "a c" given ARCH=x86_64;
please see doc/archdep.txt for a more elaborate description
and a conversion script.
This one reduces the amount of output that's only
interesting when one is actually watching the console
during builds (at least the early stage) -- these tend
to look boilerplate and be useless when inspecting the
output of a large batch build like [[regular]] one.
0.6.3 has introduced some changes that were deemed incompatible
with t6/p6 branches; it should be possible to restore compatibility
at least for non-EFI images but the effort required hasn't been
up for grabs so far.

Aimed at live images at first but should cover installers as well.
This has been brewing for quite some time and while the proper
implementation is considerably more complex (and hard to do)
looks like there's demand for the particular important use case,
namely LiveCDs for Russian users, so this code has been shared
with a few people before merge.
stage2 has been thinking it's synonymous with propagator
and used to usurp kernel's belongings either; carefully
tear scripts apart so that kernel feature makes sure
initrd gets generated, and stage2 (which is still all
about propagator) cares for its bits.
This one is long overdue as I keep forgetting to update
the published copy of generated documentation all the time.
Note that you must pass DOCS_PUBLISH (as a local directory
or host:dir suitable for rsync/ssh) via make arguments,
environment or ~/.mkimage/profiles.mk file.
The goals listed are pretty important to have them ordered
by priority; collaboration is definitely more important
than dynamic range of release managers' experience.
This change is done to reduce ambiguity in some cases;
the previous intention has been to ease navigation when
staying in a particular directory, now it's been changed
in favour of convenient toplevel `git grep' in fact.
Both variants have their pros and cons, I just find myself
leaning to this one by now hence the commit. Feel free to
provide constructive criticism :)
Some path-related bitrot has also been fixed while at that.
The behaviour that sort of settled didn't actually follow
the principle of the least surprise when one really wanted
to have BUILDDIR available for inspection; DEBUG=2 would be
effective to achieve that but CLEAN=0 would not.
Thanks led@ for spotting and reporting this.
Overview of the changes:
- ARM support: separate ext2 /boot, no LILO
- avoid race condition with devmapper
- trap ERR so that -e in shebang doesn't result in extra cleanup hassle
- configurable root filesystem type (ext4 by default)
- jumps through parted hoops
Details:
1. LILO is x86-specific while the rest of the script can be used
to prepare e.g. Marvell ArmadaXP or CuBox images; we can generally
count on uboot supporting ext2 for relatively sane platforms but
not ext4 that would be a better root filesystem performance-wise.
2. Apparently /dev/mapper/loopXpY can be still missing at the time
when kpartx returns and pop up a bit later... sit there, wait
and check for it.
3. If something went wrong with any command of the script it would bail out
due to -e in shebang; it is now better to clean up the loopback device
and its mappings in this situation either.
4. One size doesn't fit all, really.
5. The parted sizing was sloppy as in broken, now it's just half insane.
Someone's decision to stick units and auto-alignment knobs into
a single one was apparently hilarious...
http://www.gnu.org/software/parted/manual/parted.html#unit
Manual loop/dm cleanup is described in documentation just in case.
/boot size meter is suboptimal in terms of additional I/O incurred,
will be most likely rewritten to make use of advance "du -s".
The original mkisofs would only care for the proper ISO9660 image
but we've switched to xorriso which is able to perform the hack
to yield UEFI hybrid images; thus no need for the postprocessing.
Requires mkimage >= 0.2.5 and xorriso (obviously).
Folks have been wondering already whether e.g. t6 breakage
qualifies as a bug; it does indeed unless the "broken" part
depends on the features not available with that branch yet,
e.g. EFI support.
That is, p6/t6 continue to use 3.81 (while providing 3.82
alongside with it), and Sisyphus has moved to 3.82 before
p7/t7. We support both versions by now.
The initial sketch did work but was somewhat redundant
while lacking the knob conveniently change output directory
as well as means to get it cleaned up.
See http://www.opennet.ru/openforum/vsluhforumID3/86239.html#1
for a query that has led to this one; in particular,
- xdm dropped (won't log in root and there are no users yet);
- network is brought up and configured via DHCP by default;
- apt-get works out-of-box;
- default image size is twice the chroot size.
This part of docs was pleading to put it into a small shell
script; it was done to facilitate kas@' debugging efforts
so that qemu-system-ppc might eventually get fixed, thus
livecd-qemu-arch package now "obsoletes" this file.
Another feature suggested by Michael Radyuk (torabora):
some images are known alpha/beta quality, it's more handy
to just state this at the build time than to rename by hand.
