Merging /usr into the root filesystem isn't the plan.  Usrmerge moves
everything into /usr, which seems much less likely to strain your
partitioning setup.  It's still possible, of course, which must be why
the usrmerge script needs a check_free_space() function.

"Storage is tight" is already trouble, especially when you're trying
to download and install new versions of GNOME and LibreOffice and so
on as part of a distribution upgrade; see Release Notes 4.4.3.
