I currently use genext2fs, followed by tune2fs to add the journal and e2fsck to fix the incorrect FS version number. But it's extremely inefficient, especially since genext2fs first builds the filesystem in memory before committing to the output image. Not good when you want to create a 500GB partition :-) Regards, Arnout -- Arnout Vandecappelle arnout at mind be Senior Embedded Software Architect +32-16-286540 Essensium/Mind http://www.mind.be G.Geenslaan 9, 3001 Leuven, Belgium BE 872 984 063 RPR Leuven LinkedIn profile: http://www.linkedin.com/in/arnoutvandecappelle GPG fingerprint: 7CB5 E4CC 6C2E EFD4 6E3D A754 F963 ECAB 2450 2F1F
