Re: [Libguestfs] About Guest running Tiny Core Linux

It loads the main operating system root partition as a single large initramfs, with optional modules loaded [somehow -- not sure of the exact mechanism] as squashfs filesystems. There's nothing wrong with that of course, but it makes it challenging to have 'guestfish -i' open with the TCL root filesystem, and thus programs like 'virt-cat', 'virt-ls' etc are unlikely to work in the way you expect. There's probably not much we can do except have inspection simply identify that it is TCL.
