6 | # Poky-tiny is intended to define a tiny Linux system comprised of a | ||
7 | # Linux kernel tailored to support each specific MACHINE and busybox. | ||
8 | # Poky-tiny sets some basic policy to ensure a usable system while still | ||
9 | # keeping the rootfs and kernel image as small as possible. | ||
10 | # | ||
11 | # The policies defined are intended to meet the following goals: | ||
12 | # o Serial consoles only (no framebuffer or VGA console) | ||
13 | # o Basic support for IPV4 networking | ||
14 | # o Single user ash shell | ||
15 | # o Static images (no support for adding packages or libraries later) | ||
16 | # o Read-only or RAMFS root filesystem | ||
17 | # o Combined Linux kernel + rootfs in under 4MB | ||
18 | # o Allow the user to select between eglibc or uclibc with the TCLIBC variable | ||
19 | # | ||
20 | # This is currently a partial definition, the following tasks remain: | ||
21 | # [ ] Integrate linux-yocto-tiny ktype into linux-yocto | ||
22 | # [ ] Define linux-yocto-tiny configs for all supported BSPs | ||
23 | # [ ] Drop ldconfig from the installation | ||
24 | # [ ] Modify the runqemu scripts to work with ext2 parameter: | ||
25 | # runqemu qemux86 qemuparams="-nographic" bootparams="console=ttyS0,115200 root=0800" | ||
26 | # [ ] Modify busybox to allow for DISTRO_FEATURES-like confiruration | ||
