Subject: wipe partitiontable after early exits
X-Git-Url: https://git.proxmox.com/?p=pve-installer.git;a=commitdiff_plain;h=34e44994194ce62fa8719e249bf16785628e44ec

wipe partitiontable after early exits

by wiping the partition table after the initial sanity checks regarding
minimal size and blocksize of the device, no data is destroyed for an
install that would fail in any case.
