extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem SYNOPSIS
extlinux [options] directory DESCRIPTION
EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem. It works the same way as SYSLINUX, with a few slight modifications. It is intended to simplify first-time installation of Linux, and for creation of rescue and other special-purpose boot disks. The installer is designed to be run on a mounted directory. For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run the following command: extlinux --install /mnt OPTIONS
-H, --heads=# Force the number of heads. -i, --install Install over the current bootsector. -O, --clear-once Clear the boot-once command. -o, --once=command Execute a command once upon boot. -M, --menu-save=label Set the label to select as default on the next boot -r, --raid Fall back to the next device on boot failure. --reset-adv Reset auxiliary data. -S, --sectors=# Force the number of sectors per track. -U, --update Updates a previous EXTLINUX installation. -z, --zip Force zipdrive geometry (-H 64 -S 32). FILES
The extlinux configuration file needs to be named extlinux.conf and needs to be stored in the extlinux installation directory. For more information about the contents of extlinux.conf, see syslinux(1) manpage, section files. BUGS
I would appreciate hearing of any problems you have with SYSLINUX. I would also like to hear from you if you have successfully used SYS- LINUX, especially if you are using it for a distribution. If you are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems. There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To join, send a message to with the line: SEE ALSO

fsadm - utility to resize or check filesystem on a device SYNOPSIS
fsadm [options] check device fsadm [options] resize device [new_size[BKMGTEP]] DESCRIPTION
fsadm utility checks or resizes the filesystem on a device. It tries to use the same API for ext2, ext3, ext4, ReiserFS and XFS filesys- tem. OPTIONS
-e, --ext-offline Unmount ext2/ext3/ext4 filesystem before doing resize. -f, --force Bypass some sanity checks. -h, --help Display the help text. -n, --dry-run Print commands without running them. -v, --verbose Be more verbose. -y, --yes Answer "yes" at any prompts. new_size Absolute number of filesystem blocks to be in the filesystem, or an absolute size using a suffix (in powers of 1024). If new_size is not supplied, the whole device is used. DIAGNOSTICS
On successful completion, the status code is 0. A status code of 2 indicates the operation was interrupted by the user. A status code of 3 indicates the requested check operation could not be performed because the filesystem is mounted and does not support an online fsck(8). A status code of 1 is used for other failures. EXAMPLES
Resize the filesystem on logical volume /dev/vg/test to 1000 megabytes. If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be unmounted prior the resize. All [y|n] questions will be answered 'y'. fsadm -e -y resize /dev/vg/test 1000M ENVIRONMENT VARIABLES
TMPDIR The temporary directory name for mount points. Defaults to "/tmp". DM_DEV_DIR The device directory name. Defaults to "/dev" and must be an absolute path. SEE ALSO
