RHBZ Bug 962143.
Summary: The installer doesn''t support resizing Btrfs volumes, and also
doesn''t support placing /boot on Btrfs.
A further consequence is that the "guided" path for the installer
(i.e. the more automated, non-custom path) is unable to perform an installation
of Fedora 19 along side Fedora 18. My question is, resize Btrfs has been in
btrfs-progs since 0.16 which dates back to 2008. So I''m wondering how
reliable Btrfs shrinking is?
Is it mature enough for a major distribution''s installer to actively
allow the shrinking of the volume by 500MB-1000MB to make room for a new /boot
on ext4?
It seems less risky to support /boot in a new subvolume on the existing Btrfs
volume, but only GRUB2 supports and comes with another consequence (grubby bug,
will post separately).
