A commit prior to e2fsprogs 1.43 release accidentally removed a mke2fs.conf flag and resulted in mke2fs becoming very slow (takes 5 minutes to format a 1.5TB disk as opposed to <1 minute). There has been a fix upstream, and I propose that we import it util next e2fsprogs release.

commit b4b5293ca2cd62ee1beb492def34ba1928641024 Author: Lars Wendler <polynomial-c@gentoo.org> Date: Wed Oct 26 09:49:07 2016 sys-fs/e2fsprogs: Revbump to add back uninit_bg option (bug #598100). This option was accidentally removed in the 1.43 development cycle which caused mke2fs to take a very long time because it initialized all of the block group metadata. Committing straight to stable where 1.43.3-r0 was stable. Package-Manager: portage-2.3.2 Signed-off-by: Lars Wendler <polynomial-c@gentoo.org>
