I am using libguestfs tool on Fedora 30. libguestfs version: 1.40.2 libguestfs-tools-c RPM package version: libguestfs-tools-c-1.40.2-4.fc30.x86_64 I have a question about `virt-tar-out`. ``` $ rpm -qf /usr/bin/virt-tar-out libguestfs-tools-c-1.40.2-4.fc30.x86_64 ``` Current master's `fish/virt-tar-out` https://github.com/libguestfs/libguestfs/blob/master/fish/virt-tar-out is almost same with my local `/usr/bin/virt-tar-out` except bash path. ``` $ diff fish/virt-tar-out /usr/bin/virt-tar-out 1c1 < #!/bin/bash - --- > #!/usr/bin/bash - ```

## case1: convert CentOS7 aarch64 iso image to the tar file. ``` $ wget http://mirror.centos.org/altarch/7.6.1810/isos/aarch64/CentOS-7-aarch64-M... ``` ``` $ virt-tar-out -a CentOS-7-aarch64-Minimal-1810.iso / foo.tar virt-tar-out: no operating system was found on this disk

If using guestfish ‘-i’ option, remove this option and instead use the commands ‘run’ followed by ‘list-filesystems’. You can then mount filesystems you want by hand using the ‘mount’ or ‘mount-ro’ command. If using guestmount ‘-i’, remove this option and choose the filesystem(s) you want to see by manually adding ‘-m’ option(s). Use ‘virt-filesystems’ to see what filesystems are available. If using other virt tools, this disk image won’t work with these tools. Use the guestfish equivalent commands (see the virt tool manual page). ``` This works when running `guestfish` directly like this. ``` $ guestfish -a CentOS-7-aarch64-Minimal-1810.iso --ro <<EOF run list-filesystems EOF /dev/sda: iso9660 ``` ``` $ guestfish --ro -a CentOS-7-aarch64-Minimal-1810.iso -m /dev/sda tar-out / foo.tar $ echo $? 0 $ du -sh foo.tar 768M foo.tar ``` ## case2: convert CentOS7 ppc64 iso image to the tar file. ``` $ wget http://mirror.centos.org/altarch/7.6.1810/isos/ppc64/CentOS-7-ppc64-Minim... ``` ``` $ virt-tar-out -a CentOS-7-ppc64-Minimal-1810.iso foo.tar virt-tar-out: no operating system was found on this disk If using guestfish ‘-i’ option, remove this option and instead use the commands ‘run’ followed by ‘list-filesystems’. You can then mount filesystems you want by hand using the ‘mount’ or ‘mount-ro’ command.

I should use `guestfish` command directly?
