IMHO /etc/hosts is just as unreliable as /etc/fstab.
I'd rather test for /bin/sh being present and being an ELF executable or
shared object.
That won't work with recent Fedora/RHEL/CentOS systems due to the
UsrMerge: if /usr is in a separate partition, /bin/sh "exists" there
too, and thus that partition would be detected as root.
