| # 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: | |
| . "${srcdir=.}/tests/init.sh"; path_prepend_ ./src | |

| # FIXME: for now, skip it unconditionally | |
| skip_ temporarily disabled | |
| # FIXME: define cleanup_ to do the umount | |
| # FIXME: use mktemp | |
