    - bash is *required* for dracut initramfs to work correctly, rel 3

At some point dracut started to pretend mksh is supported as /bin/sh
inside initramfs but that's simply not true. Default fallback is
whatever system /bin/sh is linked which in our case is mksh hence broken
initramfs in some cases. Going back to previous default "dash" helped in
my case (lvm) -- are you sure it really needs bash? And perhaps maybe

I know for certain that mksh does not. And very silently at that. Initramfs
just doesn't detect encrypted partitions.

let's leave a possibility to customize shell and instead of hardcoding
bash use:

add_dracutmodules+=" bash "

which effectively changes default shell.

I'm not so sure. What I found in the code is that dracut first installs
/bin/sh and then shell modules (00bash, 00dash, 00mksh) as needed.
But, those modules do not create /bin/sh if it already exists, and since
that symlink is installed first it will not be re-created.

Works for me. The place where dracut installs /bin/sh -> mksh is at first
script with /bin/sh shebang:


Hence shell modules (bash/dash/mksh) are ordered with 00 before any such
script could be installed.

Tested dash, works. Generic initramfs detected and booted off encrypted root.

   So, can I safely remove entry:

   hold = dracut*

   from my config?

   Last dracut, that works with LUKS was dracut-054. (always good to have
   PLD Rescue ;-) )

   Thanks for fix!
