Tinyramfs

Currently tinyramfs is incomplete, don't expect that everything is working

Features

No local's, no bashisms, only POSIX shell
Portable, not distro specific
Easy to use configuration
Build time and init time hooks
LUKS (detached header, key), LVM
mdev, mdevd, eudev, systemd-udevd

Dependencies

POSIX utilities
POSIX shell
switch_root
mount
cpio
strip
- Optional
blkid
- Required for UUID, LABEL, PARTUUID support
mdev OR mdevd OR eudev OR systemd-udevd OR CONFIG_UEVENT_HELPER
- 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)
- Not required for monolithic kernel

Notes

busybox modutils doesn't handle soft dependencies (modules.softdep). You must manually copy them using hooks
busybox and toybox blkid doesn't support PARTUUID. You must use util-linux blkid for PARTUUID support

Installation

git clone https://github.com/illiliti/tinyramfs
cd tinyramfs
make install
vi /etc/tinyramfs/config # edit config for your needs
tinyramfs -o /boot/initramfs-<ver> # replace <ver> with current kernel version

TODO finalize and document kernel command-line parameters
