mke2fs hung

Hello all.

Seems the first install on (used) bare metal HW found a problem.
Previous tests with a VM worked OK.

During the first reinstall on a bare metal server that already contained 
an installed system, mke2fs hung.

I switched to a second console to look at the issue and found that 
stderr tmpfile for mke2fs contains "Found a dos partition table in 
/dev/sda2" and stdio tmpfile "prompts" with "Proceed anyway? (n/Y)". 
Giving a 'y' in the main console lets it proceed, but it shouldn't have 
stopped.

It seems the wipefs -af /dev/sda* before parted is not enough. Maybe a 
second wipefs is needed between parted and mkfs [*]?

IIUC it's quite a corner case (new gpt partition overlapping an old dos 
extended partition), but probably it's better to handle it.

HIH.
