There's a proposed anaconda patch ATM which would disallow mounting an existing partition as /boot or /var (or any subdirectory of those except /var/www ) without reformatting it. i.e., you can't reuse an existing partition with those mountpoints.
I'm curious to know if anyone / many people do this, and if so, if there's a particularly good use case for it; if so, we might want to provide that feedback to the anaconda folks.
There are a few references to using shared /boot on Google, but not that many, and mostly for crazy multiboot configurations that we really don't want to be stuck dealing with. Does anyone know of a really sensible use case for this?
For the record, this is actually re-hooking up code that was used in oldUI - that is, F17 and earlier - but in oldUI it just produced a warning you had to click through; the current patch flat disallows it. The main driving force for this is https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=1074358 , as it keeps turning out to be annoyingly tricky to make sure that only newly- installed kernels have their initramfs regenerated when installing to a shared /boot partition.
