    I've done that also, during 10 years of my professional life
(2005-2015): I was running Debian on a bunch of diskless Powerpc-based
SBCs, and I only used the userspace from Debian; kernel and initrd phase
were custom. This is a perfectly feasible thing; you just need to
carefully build what the userspace init expects to find when you
switch_root, like /dev already mounted and populated and /proc, /sys and
/run already mounted. It takes some time to learn and maintain, but it
gives you some autonomy.
