In this case we're using libext2fs to build an appliance filesystem, used to boot a small Linux system which is then run under qemu by libguestfs. This appliance is completely rebuilt automatically under many circumstances, for example a host package upgrade (eg. upgrading the kernel), so it's not a long-lived filesystem that would cause a problem. Rebuilding only takes a few seconds. The process is described in more detail here: http://libguestfs.org/supermin.1.html#SUPERMIN-APPLIANCES >From our point of view the only issue are some prebuilt appliances which we have provided to other distributions that cannot / don't want to use supermin (http://download.libguestfs.org/binaries/appliance/) and at some point I'm going to have to rebuild these using the fixed supermin.
