Re: aboot unzip "unknown compression method" on recent (post 6.4) kernels?

Following up on your suggestion, I downloaded the mattst88 github 
version of aboot, built it successfully (once realizing the need for 
libext2fs-dev!), swriteboot'ed it, and ... no difference. Same unzip error.

Note that the upstream version has files that were updated ~3 years ago 
(consistent with being pre20200212), but I found that aboot's 
hello-world string still says 1.0_pre20040408, so your boot console 
won't tell you which version you actually have written to the partition.

     See: include/config.h:#define ABOOT_VERSION "1.0_pre20040408"

https://github.com/mattst88/aboot/blob/master/include/config.h

I wasn't able to build the debian version from the "aboot" source 
package. "debian/rules build" seems to fail at the linking stage due to 
multiple definitions. Errors below.

     Thanks,
