Features

• No local's, no bashisms, only POSIX shell
• Easy configuration
• mdev, mdevd, eudev
• LUKS
• LVM

Dependencies

• POSIX shell
• POSIX utilities
• switch_root
• readlink
• install
• setsid
• mount
• cpio
• gzip
  • Required by default
• strip
  • Optional
• blkid
  • Required for mdev/mdevd
• mdev OR mdevd OR eudev
  • systemd-udevd not tested
• lvm2
  • Required for LVM support
• cryptsetup
  • Required for LUKS support
• kmod OR busybox modutils with this patch (already included in KISS Linux)

• cp -P is broken in toybox, see here
