is there any reason why Reiser4 SFRN 4.0.1-enabled Debian should not run on Power8? I assume GPT should be selected whereas previously I have tested -- on AMD64 baremetal and cloud -- only MSDOS disk partitioning.
There might be some problems with the endianness of the system. I have tested Reiser4 on 32bit PowerPC several years ago and as far as I remember, mounting and using a preformatted partition (mkfs done on an x86 machine) was possible, but a partition formatted on PowerPC was unusable. I can repeat the tests, if you are interested. -- Jonáš Vidra, vidra.jonas@seznam.cz
