[pkg-lxc-devel] Bug#883912: lxc-create(1) incorrectly says default fstype is ext4

[Jean-Michel Vourgère]

Package: lxc
Version: 1:2.0.7-2
Severity: minor

Dear Maintainer,

man lxc-create says:
> --fstype FSTYPE will create an FSTYPE filesystem on the LV, rather than the
> default, which is ext4.

However, when a container is created with lvm without the --fstype option
it gets an ext3 partition.

In src/lxc/bdev/lxclvm.c, in lvm_create:
> fstype = specs->fstype;
> if (!fstype)
>         fstype = DEFAULT_FSTYPE;

In src/lxc/bdev/bdev.h:
> #define DEFAULT_FSTYPE "ext3"

I expected the manual to say the default is ext3, not ext4.

Cheers
