Wonderful! The hard logic. Yes, if You have too big /boot then You can
have lot of backup initrd there. But we want keep it small, isn't?.

It should not be option, it should be main functionality. And all
"clutter" should go out of /boot.

How long You will repeat this absurdity? This will not "admin error" if
You will not use /boot for backup and temporary files. There are some
other places for this purposes, do You know?

OK. I see, but there are nothing what I don't already know at least
related to this discussing. That is simple algorithm:
1. You backup old intrd image
2. You create new image as temporary file.
3. You move new image in place of old one.
4. If it fail due to low disk space You move back the old image
into its' place.
And then You proudly say me "that was done for better reliability"! But
this is poor "reliability". This way You solve only one case, when
system become unbootable: when new image are already overridden by old
one, but there are not enough space for that and You have not neither
new nor old image. But there are other cases when system become
unbootable, for example due to contents of new image itself. This is
common case, when You can not boot with new image, but old one already
overridden, because image was generated few times before system boot.
Please, don't tell me, this is "admin error" again.
I don't understand, why You don't agree to move backup and temporary
files out of /boot? In this case Your idea of "reliability" remain in
place: when You can not replace old image with new one due to low disk
space, You will roll back to the old image as You do this now.
