Subject: [PATCH] helper: Don't crash if SUPERMIN_DTB is set and no --dtb on
|
|
the command line.
|
|
|
|
Libguestfs uses supermin-helper -f checksum w/o --dtb. Setting the
|
|
SUPERMIN_DTB environment variable would cause supermin-helper to
|
|
crash. Instead of crashing, just ignore SUPERMIN_DTB.
