Comment 1 Richard W.M. Jones 2013-08-29 12:45:25 UTC
This is actually user error (it wasn't obvious, even to me).

If you write:

><fs> tar-out / /tmp/excludes1 excludes:"hello*"

then the list of strings passed to libguestfs is:

[ "\"hello*\"" ]

ie. the quotes are included in the string.  libguestfs
correctly passes this, quoting and everything, to the
tar command.

The correct command is:

><fs> tar-out / /tmp/excludes1 "excludes:hello*"

or you can omit the quotes (in this case).

Nevertheless, I've make the use of the optional excludes
pattern more robust, and also added a regression test:

Comment 2 Richard W.M. Jones 2013-08-29 14:22:40 UTC
Fix also included in libguestfs-1.20.10-4.el6 (note
there is no separate bug for RHEL 6, I just included
the fix in the routine build).

Verified with libguestfs-1.22.6-16.el7.x86_64

It works with two ways
