Hey Nikos,
First, you can set your own kernel arguments via the `kernel_args`
parameter in the `set_kernel_disk_worload` function to do this sort of
thing, there's no need to modify the source. You can do something like this:
```
board.set_kernel_disk_workload(
kernel=Resource(
"riscv-bootloader-vmlinux-5.10",
),
disk_image=Resource(
"riscv-ubuntu-20.04-img",
),
kernel_args=get_default_kernel_args() + ["init=/root/gem5_init.sh'"],
)
```
Anyway, to answer your question: It looks like you made some error when
creating your disk image and set things up in a read-only partition. That'd
be my best guess at this point. You should try to ensure you setup the
partitions correctly in the disk image. Given I don't know how you created
this new image, I can't help much further.
We should have a new RISCV disk image available by the end of today (it
took as a bit longer than expected). It still takes some time to boot, but
it's more stable than the one we currently provide.
Out of curiosity, how did you remove your systemd processes? How are you
building this disk image? With what OS are you booting?
Kind regards,
Bobby

Dear all, Bobby and Hoa,
I add this command (self.workload.command_line += '
init=/root/gem5_init.sh') in 169 line of
gem5/src/python/gem5/components/boards/kernel_disk_workload.py and I
build the gem5. Using this command, the gem5 is able to boot after 10
minutes (without a large number of systemd services). However, when it
boots and read the gem5_init.sh, I get the following:"cannot create
/tmp/script: Read-only file system". And of course, nothing can be
written in the filesystem. How can I resolve this?
Thank you in advance!!!
Best regards,
Nikos
