+# 9010-fix-toram.hook.chroot — patch live-boot toram to work with tmpfs (no O_DIRECT)
+#
+# live-boot tries "losetup --replace --direct-io=on" when re-associating the
+# loop device to the RAM copy in /dev/shm.  tmpfs does not support O_DIRECT,
+# so the ioctl returns EINVAL and the verification step fails.
+#
+# The patch replaces the replace call so that if --direct-io=on fails it falls
+# back to a plain replace without direct-io, and also relaxes the verification
+# to a warning so the boot continues even when re-association is imperfect.
+set -e
