From Gentoo Wiki (test)
e2fsprogs is a suite of standard userspace programs for ext2, ext3, and ext4 filesystems.
Installation
USE flags
USE flags for sys-fs/e2fsprogs Standard EXT2/EXT3/EXT4 filesystem utilities
+tools
|
Build extfs tools (mke2fs, e2fsck, tune2fs, etc.) |
archive
|
Add support for mke2fs to read a tarball as input. This allows not needing privileges. Needs app-arch/libarchive. |
cron
|
Install e2scrub_all cron script |
fuse
|
Build fuse2fs, a FUSE file system client for ext2/ext3/ext4 file systems |
nls
|
Add Native Language Support (using gettext - GNU locale utilities) |
static-libs
|
Build static versions of dynamic libraries as well |
test
|
Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently) |
Emerge
The sys-fs/e2fsprogs package and should be available as part of the default system set.
