FreeBSD makefs(8) for Linux / *BSD

About

• FreeBSD makefs(8) + HAMMER2 support + exFAT support

Supported platforms

• Linux, Cygwin, FreeBSD, NetBSD, OpenBSD, DragonFly BSD

Requirements

• C compiler

• libuuid.so and <uuid/uuid.h> on Linux (unless HAMMER2 support is disabled on build)

Supported file systems

file system	-t option name	original implementation
UFS	ffs (default)	FreeBSD makefs(8)
FAT	msdos	FreeBSD makefs(8)
ISO9660	cd9660	FreeBSD makefs(8)
Version 7 Unix file system	v7fs	NetBSD makefs(8)
HAMMER2	hammer2	DragonFly BSD makefs(8)
exFAT	exfat	https://github.com/relan/exfat

Build

• By default all supported file systems above are enabled. Use gmake(1) on *BSD.

    $ cd makefs
    $ make
  

• Specify USE_HAMMER2=0 to disable HAMMER2 support.

    $ cd makefs
    $ make USE_HAMMER2=0
  

• Specify USE_EXFAT=0 to disable exFAT support.

    $ cd makefs
    $ make USE_EXFAT=0
  

Install (optional)

    $ cd makefs
    $ make && make install

Uninstall (optional)

    $ cd makefs
    $ make uninstall

Usage examples

• 4.4BSD FFS

    $ ./src/makefs -t ffs /path/to/img /path/to/directory
  

• FreeBSD UFS2

    $ ./src/makefs -t ffs -o version=2 /path/to/img /path/to/directory
  

• ISO9660

    $ ./src/makefs -t cd9660 /path/to/img /path/to/directory
  

• HAMMER2

    $ ./src/makefs -t hammer2 /path/to/img /path/to/directory
  

• FAT12/16/32 (file size required)

    $ ./src/makefs -t msdos -s 1g /path/to/img /path/to/directory
  

• exFAT (file size required)

    $ ./src/makefs -t exfat -s 1g /path/to/img /path/to/directory
  

Notes

• Build confirmed on Fedora, Ubuntu, Cygwin, FreeBSD, NetBSD, OpenBSD, DragonFly BSD on x86_64.

• Due to lack of UFS standard among vendors, use an appropriate "-o ufstype=..." mount option to mount UFS on Linux.

  • Use "-o ufstype=44bsd" (4.4BSD) for an image created with "-o version=1" or the default.

  • Use "-o ufstype=ufs2" (FreeBSD UFS2) for an image created with "-o version=2".

• ZFS support which exists in recent FreeBSD makefs(8) is unsupported.

Bugs

• mtree(5) related options are currently unsupported.

  • -F option, -N option, and mtree file input will fail with an error message.

• v7fs support compiles, but "-t v7fs" option is broken.

  • "-t v7fs" option is broken on NetBSD makefs(8) as well.
