[Bug 1807288] Re: mkfs.ext4 -d $directory_with_acls leads to EINVAL

[Steve Langasek]

Also reproducible without the -O options.

Can confirm that this works with e2fslibs from e2fsprogs 1.43.4:

$ dpkg -x ./e2fslibs_1.43.4-2_amd64.deb e2fsprogs
$ LD_LIBRARY_PATH=./e2fsprogs/lib/x86_64-linux-gnu/ e2fsprogs/sbin/mkfs.ext4 -L lala -T default fake.img -d ./stuff/
$ sudo mount ./fake.img /mnt
$ getfacl /mnt/journal/
getfacl: Removing leading '/' from absolute path names
# file: mnt/journal/
# owner: vorlon
# group: vorlon
user::rwx
group::r-x
group:adm:rwx
mask::rwx
other::r-x

$ sudo umount /mnt
$
