Re: [PPC] Installation freeze-up

 

Congratulations :-)

I think those commands are only a temporary switch off of zram. So after
reboot it will re-appear (and the installed system is not affected at
all). You need to do something else, for example remove the package
zram-config to switch it off completely and persistently.

Best regards
Nio
