Comment 13 for bug 1814598

Podesta,

ESET SysRescue
==============

I discovered that the initrd file on the original ISO (eset_sysrescue_live_enu.iso) has the wrong extension. The file name should be "initrd.gz" because it uses "gz" compression, not "lz" compression. I recommend opening a bug with ESET SysRescue to correct this on their live ISO.

The output of the "file" command shows that "initrd.lz" is "gzip compressed data"...

Cubic
==============

Cubic ~does~ correct the file extension based on the compression type.
However Cubic overlooks updating the filename in grub.cfg, and this is what needs to be fixed.
