This is only just for "start point" and is a DRAFT that works (just setup correct directories and images names). Nothing is stripped, I working on it. Size of iso generated is 782237696 bytes (746MB) http://github.com/djgera/archiso2dual -- Gerardo Exequiel Pozzi ( djgera ) http://www.djgera.com.ar KeyID: 0x1B8C330D Key fingerprint = 0CAA D5D4 CD85 4434 A219 76ED 39AB 221B 1B8C 330D

OK, usrshare split is done, results: 726663168 bytes (692 MB) just spliting /usr/share from both root-image.sqfs and making usrshare.sqfs 701497344 bytes (668 MB) like previous but deleting from usrshare.sqfs doc/, info/ and doc/.

OK, usrshare split is done, results:

701497344 bytes (668 MB) like previous but deleting from usrshare.sqfs doc/, info/ and doc/.

Script execution time take about 3 minutes. Just with second result (692MB) is OK, but going beyond:

Removing, /boot (unused at all), /usr/include and /usr/src (after all there is no gcc on the live medium) size is 685768704 (653MB). -- Gerardo Exequiel Pozzi ( djgera ) http://www.djgera.com.ar KeyID: 0x1B8C330D Key fingerprint = 0CAA D5D4 CD85 4434 A219 76ED 39AB 221B 1B8C 330D

I think everything below 700MB is fine as it still fits on a standard CD-R. BTW: I am just testing xz compression and this will give is a lot more free space. For example the x86_64 core repo went down from 223 MB to only 149 MB. -- Pierre Schmitz, https://users.archlinux.de/~pierre

Add another "profile" to split out lib/modules from root-images. In this way can boot a 64 bits kernel with 32 bits userspace. This third option is now implemented with three isomounts files. -- Gerardo Exequiel Pozzi ( djgera ) http://www.djgera.com.ar KeyID: 0x1B8C330D Key fingerprint = 0CAA D5D4 CD85 4434 A219 76ED 39AB 221B 1B8C 330D
