1bit OS: the boot fixes the VM test found (after #56) - #60
Merged

Conversation
#56 merged before these landed on its branch: - sd_mod: a USB stick never became a disk, so 1BIT-DATA (models, SSH keys, 1bit.conf) was never mounted. - The initramfs is packed with every file owned by root and nothing group/world-writable, /root 700: Dropbear refused key logins before. - vmtest.sh: lavapipe listed for llama.cpp, a 4096-token context and 16 GB in the VM, and the chat request retried (1bit serve answers /v1/models before its backend is ready). VMTEST PASS: UEFI boot from the USB image, SSH in ~9 s, 1bit serve answered. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
