Re: [9front] Problems building Raspberry Pi image

[cinap_lenrek]

the issue is that it binds /sys/lib/dist/usr over /usr. and you probably
dont have a separate repo to build the iso from but use the your root
filesystem as /n/src9.

so to get arround this, try to create the target file in some other
directory, say /tmp.

i'll see if i can get arround this limitation in the mkfile.

It detects the sd card now, many thanks for your help.

It works! the building process completed successfully. But when I try
to boot the generated image, the device for the sd card is not there.

Attached I leave the building log and a image of the boot screen.

Thanks again

Re: [9front] Problems building Raspberry Pi image

[cinap_lenrek]

i found a solution. you can apply the following change in /sys/lib/dist/mkfile:

diff -r ea7fc8e2526a sys/lib/dist/mkfile
--- a/sys/lib/dist/mkfile	Fri Mar 29 06:35:41 2019 +0100
+++ b/sys/lib/dist/mkfile	Sat Mar 30 05:42:27 2019 +0100
@@ -146,4 +146,5 @@
 	bind mail/lib /n/src9/mail/lib
 	bind ndb /n/src9/lib/ndb
 	bind -a adm/timezone /n/src9/adm/timezone
+	aux/stub -d /n/src9/usr
 	bind usr /n/src9/usr

this works as aux/stub mounts itself on /n/src9, so the bind
for /n/src9/usr will not override /usr in the root filesystem
but the stub directory from aux/stub.
