# This is just for the record.
# This test is not run.
# Test for the 2005-10-13 patch to lib/mkdir-p.c that fixed this sort
# of bug in mkdir:
#
# "mkdir -p /a/b/c" no longer fails merely because a leading prefix
# directory (e.g., /a or /a/b) exists on a read-only file system.
#
# Demonstrate the problem, as root:
mount='sudo mount'
cd /tmp \
&& dd if=/dev/zero of=1 bs=8192 count=50 \
&& dd if=/dev/zero of=2 bs=8192 count=50 \
&& mkdir -p mnt-ro && mkfs -t ext2 1 && mkfs -t ext2 2 \
&& $mount -o loop=/dev/loop3 1 mnt-ro \
&& mkdir -p mnt-ro/rw \
&& $mount -o remount,ro mnt-ro \
&& $mount -o loop=/dev/loop4 2 mnt-ro/rw
mkdir -p mnt-ro/rw/sub || fail=1
# To clean up
umount /tmp/2
umount /tmp/1
