Dear Linux folks,


Trying to reduce the boot time of standard distributions, I would like=20
to get rid of the initrd. The initrd is for mounting the root file=20

means loading the bus driver for the drive and the file system driver.

I would expect most end user systems to use at least one of LVM and
cryptsetup, which need user-space to configure them.

Debian has the "tiny-initramfs" package that covers the simple cases
you're targetting, and can be used instead of initramfs-tools or
dracut.  The upstream of that is:
<https://github.com/chris-se/tiny-initramfs/>.

But I don't anticipate that we would change the default initramfs
builder any time soon.

Ben.
