How does ostree/rpm-ostree handle many trees where there are too many kernels+initramfses for separate /boot to hold?  On Fedora in particular, with frequent kernel updates, this seems like a problem.

Keep in mind that by default, only a maximum of 3 deployments is transiently present per OS, and default 2 persistent (in the middle of upgrading, you have 2, plus the new one, then the old one will be GC'd).  This is of course up to the client tools - OSTree supports as many deployments as you have space, but it's what at least /usr/bin/rpm-ostree and /usr/bin/ostree do.

 

But if `/boot` gets full, the filesystem will report `ENOSPC`, and the new deployment will fail, leaving your current system untouched.  `ostree admin cleanup` will delete any transiently created files.
