5 months ago Predownloading doesn't really matter if you don't also pass --external-sources to rootfs.py.
That said, 5 days in Fiwix is certainly abnormal; also, --external-sources doesn't really do anything until after the Linux kernel is built and started.
To debug this better, it would be important to know:
- your host OS (if it's a Linux distribution inside WSL1 or WSL2 on Windows, please include that as well),
- any hypervisor you might be running (besides KVM),
- whether or not you're using KVM acceleration (by default, rootfs.py tries to use KVM),
- your CPU model (some newer Intel CPUs are known to have problems in Fiwix, even when virtualized via KVM),
- the type, frequency and channel count of your RAM.
(Storage performance should have no effect in the Fiwix phase, as in Fiwix, everything happens in RAM, with no access to drives.)
Another thing you may try is making a bare metal image (using -b instead of -q), and then booting it using a normal qemu VM (without the -nographic option, so you have a real graphical console) on the same hardware. When combined with the -i option (which you are already using), in the latest code, that lets you access secondary virtual consoles as soon as the bootstrap transitions from kaem to bash as its shell. To access the secondary console, use the key combination Ctrl+Shift+F2 - in qemu, you might need to use the "sendkeys" command from the monitor console to do this, in case your host OS traps that combination.

Because of work commitments, I haven been able to touch this project since the new year. When I tried to run the bootstrap with the latest version it has been running for 5 days and it still hasn't completed. At first I thought it froze but that doesn't appear to be the case. If I come back every few hours i do see slow progress. I tested my personal fork which was pulled on 28 December 2023 on the same machine and it completed in several hours. After doing some testing, the problem appears to be FIWIX. As soon at the kexec-fiwix happens the bootstrap slows to a crawl. It behaves like it's waiting for some IO or memory operation. The bootstrap works normally using Bwrap and chroot. My command line is :
./rootfs.py -q --update-checksums --cores=4 -qr=4096 -i -s=4096
I have my files predownloaded using download-distfiles.sh. Can someone please see if they can duplicate this issue or if I'm doing something wrong please correct me.
