setup step 4 (busybox sh /lib/cryptsetup/scripts/wget_or_ask) failing "sh: bad number"

[yeupou]

sh expect $CRYPTTAB_TRIED (if [ "$CRYPTTAB_TRIED" -gt 0 ]; then) to be set so the following fails:

busybox sh /lib/cryptsetup/scripts/wget_or_ask "somepassphrase:https://example.org/encrypted_keyfile" > unencrypted_keyfile

the following works (but without passing by busybox):
CRYPTTAB_TRIED=0 /lib/cryptsetup/scripts/wget_or_ask "somepassphrase:https://example.org/encrypted_keyfile" > unencrypted_keyfile

Hmm. Complains but still works for me. Will investigate...

CRYPTTAB_TRIED is defined in /lib/cryptsetup/functions which isn't available when you execute the busybox command in a "non-initramfs" environment.
