[opensuse-buildservice] Compression format for images build
Hi all,

When I'm trying to uncompress images built by OBS (e.g. [1]) in
Windows, 7-Zip, PeaZip and WinRAR all fails. 7-Zip just failed to
recognize the tar ball, and WinRAR complained with message 'sparse
file is not supported'.

After some searching, I find this bug report for 7-Zip[2]. It seems
that sparse tar package is not supported in 7-Zip either.

I saw from here[3] that image compressing method is hard coded in, and using '-S' option for tar cmd.

Can this option be controlled by project config? So that appliances
which with Windows users as one of main audiances can be more friendly
(I'm buiding one now). It will be inconvenient if users have to use
GNUWin[4] or Cygwin tools to uncompress the image, especially for
non-tech ones.

Best Regards,


Xin Wang (
