installer erase script doesn't erase eMMC properly #45

Open networkimprov opened 8 years ago

networkimprov commented 8 years ago

Erase u-boot script needs to erase more of eMMC :-)

install -ierase

install -irootfs...gz

Partitioning /dev/disk/...

/dev/sdb2 contains a ext4 file system

Proceed anyway? (y,n)

Actual issue is the installer recreates the partition map that existed before that maps to where the existing ext4 is located which results in that prompt.

@networkimprov Only options here are to add the force flags to mkfs.ext4, or have the whole mmc erased.. I think the former option is the best idea.

networkimprov commented 8 years ago

Added -F to mkfs.ext4, commit pending.

Does your fix mean the mkfs.ext4 force flag isn't necessary?

mranostay commented 8 years ago

@networkimprov No it is still required.
