Could it be that a configure is missed or something isn't installed? e2fsprogs should be able to handle ext4 according to release notes Fine would be a wrapper for mkfs.ext4 f.e. Reproducible: Always
moon-gen-3 ~ # cd /var/log/portage/ moon-gen-3 portage # cat sys-fs\:e2fsprogs-1.40.9\:20080615-114042.log |grep -i ext4 moon-gen-3 portage # => ni sign of ext4 in compile logs at all. Changelog mentions bug #167562 and bug #156697 *** After reading a bit forums, http://www.sabayonlinux.org/forum/viewtopic.php?f=57&t=11178 means there is no reason to make ext4 available easily for normal users for now, cause ext4 is still too much unstable. Amongst other points, even original package, even in 1.40.11, there is no mkfs.ext4 at all yet: there is no ready to use bunch of commands written by author yet. The way to get ext4 commands is described in http://www.ibm.com/developerworks/linux/library/l-ext4/ ... and it is far from trivial. This should not be done in a normal ebuild. Maybe we could write a new ext4 specific ebuild for no, but I dont think there is any clan Gentoo way to bring mkfs.ext4 in soon. *** BTW, 1.40.11 is out. Can maint bump ? dev says it corrects lots of bugs.
read the relevant documentation to figure out how to use ext4 ... there's nothing to be changed in the e2fsprogs package
