To avoid too many mails, I simply sent this one with summary. I now have access to archiso.git, any issues in pushing these changes? I done some test and all works: * build i686 and x86_64 iso. * build dual iso. * boot i686 and x86_64 (all syslinux options works) * boot dual (all syslinux options works, and also autodetection) * boot with newer options for loop support (with and without copytoram) * all tests done with default install_dir "/arch" and under random name "/pepito". * also just for see image size I build images with sqfs compressed with lzma, of course this does not boot at this moment. core-dual look like: http://djgera.pastebin.com/vYMCuM6w core-i686 look like: http://djgera.pastebin.com/5puDe02m As you can see now both single and dual, share the same directory scheme. https://github.com/djgera/archiso/compare/master...experimental 7e1d2fd [syslinux-iso] Add support to squashfs compression types. 7e18035 [archiso2dual] Autodetect whether we can boot x86_64 8f6a6ab Unify scheme of sed replacements. 8bdf43e [archiso] Add support to mount iso in loopback mode. 85e3798 [syslinux-cfg] Remove joe from packages.* ed2e27e [archiso2dual] Adapt to new dir scheme of source /${install_dir}/${arch}/ f7d5cbb [syslinux-iso] Unify dir scheme with -dual images d34f2c6 [archiso] Place *.sqfs images in /${install_dir}/${arch}/ 3d46d7e [archiso2dual] Adjust to work with new dir scheme aae85f4 [syslinux-cfg] Adjust to work with new -D option of mkarchiso c186a20 [archiso] Add -D <install_dir> option to mkarchiso f139527 [archiso2dual] Modify behaviour of -S parameter af66220 [archiso2dual] Add support for squashfs compression types 487436b [archiso] Add support for squashfs compression types Thanks. -- Gerardo Exequiel Pozzi \cos^2\alpha + \sin^2\alpha = 1
