These are the deps that I know xfstests has, to build and to run:
BuildRequires: autoconf, libtool, xfsprogs-devel, e2fsprogs-devel
BuildRequires: libacl-devel, libattr-devel, libaio-devel
Requires: bash, xfsprogs, xfsdump, perl, acl, attr, bind-utils
Requires: bc, indent, quota
which isn't so bad...
(and tests are just skipped if xfsdump isn't there)
I'm not sure an xfsprogs dependency is so onerous; plenty has depended
on e2fsprogs through the years and we've lived with that ;) But
the lag time for xfsprogs to use released xfs_io functionality is a
bit of a bummer.
But I guess I don't have a great answer for who else uses xfs_io:
xfs_io(8) xfs_io(8)
NAME
xfs_io - debug the I/O path of an XFS filesystem
SYNOPSIS
xfs_io [ -adFfmrRstx ] [ -c cmd ] ... [ -p prog ] file
DESCRIPTION
xfs_io is a debugging tool like xfs_db(8), but is aimed
at examining the regular file I/O paths rather than the
raw XFS volume itself.
I guess it's not really advertised as a generic tool, and it's
in the sbin path...
I guess I could live with it either way - I suppose my main concern
is that xfstests is a mess to package for a distro, and I really like
easy access to xfs_io for my own use outside of xfstests.
