Hello Dieter
I want some coordination with you to merge my dm-snapshot branch in
master (archiso) so you can change releng scripts.
Detailed manually build steps are here [#1]
If you need more info please let me know.
Basically the changes are (from build view):
---- Single ISOs ----
* Deprecated configs/syslinux-iso in favour to configs/releng
* configs/releng uses a bash script instead of make
* Equivalence of commands is:
make net-iso -> ./build.sh net_iso_single
make core-iso -> ./build.sh core_iso_single
make [all] -> ./build.sh all_iso_single
make clean -> ./build.sh clean_single
* Note: Like with previous method, after building "core", if you build
"netinstall" you get a "core" iso called "netinstall". (TODO: I need to
fix this in a easy way)
* Important: inside the chroot you need one loopback device available (@1)
---- Dual ISOs ----
* Deprecated archiso2dual script in favour of configs/releng/build.sh
* While archiso2dual use *.iso images, build.sh use the result of
./build.sh *_iso_single commands, in other words join
${work_dir}/${arch}/iso (via hardlinks).
* No more profiles (single, split, full), since the work of profile
"split" is now done for single images.
* build.sh accept these commands for doing dual images.
./build.sh net_iso_dual
./build.sh core_iso_dual
./build.sh all_iso_dual
./build.sh clean_dual
* These commands does not trigger the build of single images. You need
to do it before.
* No issues if execute first "core" then "netinstall" (I managed it in
this case)
* No loopback device is needed for this step.
(@1) Create one, for example "mknod /dev/loop1032 b 7 1032" for 32 bit
chroot and loop1064 for 64 bits (of course this will work only if loop
module is loaded without any parameters that limit the number of loop
devices or set number of partitions).
[#1] https://wiki.archlinux.org/index.php/User:Djgera#archiso
Well, once you merge this into archiso I will temporarily disable the automatic
creation of images, hack
http://projects.archlinux.org/users/dieter/releng.git/ until it works, and
reenable automatic creation.
OK.
But yeah, first make sure that 'core' images are really core and 'netinstall'
are netinstall.
Not a big issue. This is the same bahaviour like with previous build
system. Since you not have any issue before, do not worry about that now.
What's the way to just create all images?
./build.sh all_iso_single&& ./build.sh all_iso_dual ?
Better explained in the wiki.
1) share a common directory between two chroots (32 and 64 bits) for
working directory.
2) execute in 32 bits chroot: ./build.sh all_iso_single
3) execute in 64 bits chroot: ./build.sh all_iso_single
4) execute in any chroot (don't care) : ./build.sh all_iso_dual
Steps 2 and 3 require one available loopback device in the chroot.
Step 4 do not require loopback devices like with archiso2dual.
