no clean way to build amd64 iso #215

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
currently, you can't build an amd64 iso without modifying some of the code that 
builds the current 386 iso. it seems the iso building machinery is very 386 
centric in general. it would be nice if the procedure for building an iso or 
disk for e.g. the amd64 port or the rpi port was similar to how 386 is built as 
documented at 
https://code.google.com/p/plan9front/wiki/fqa5#5.3_-_Building_an_ISO.

to build an amd64 iso, i copied /sys/lib/dist/cfg into /sys/lib/dist/cfg/386 
and put a modified copy into /sys/lib/dist/cfg/amd64 using 
bootfile=/amd64/9pc64. i also modified /sys/lib/dist/mkfile to use $objtype/cfg 
instead of the cfg directory. additionally had to modify 
/sys/lib/sysconfig/proto/cdproto to copy * for 386, since booting the amd64 iso 
depends on /386/9bootiso.

i'm not convinced having amd64 iso is such a good idea. it just complicates the 
install process.
the amd64 kernel has only a subset of the drivers the 386 kernel has so it is 
less likely to
succeed booting. all amd64 systems are also 386 systems and it is really 
trivial to build and
install amd64 binaries later after the installation.

for raspberry pi, this is a different matter. tho for that platform, you 
probably
do not want a iso file because it has no cdrom drive but a sd card image.

I agree with cinap. A possible solution would be to have options for amd64 
install on the cd (and grab the bins from the net or build them there) or a 
script that sets it all up after the installation.
