Looks like we could use a FAQ/HOWTO in this newsgroup. Not so much to stop
people from asking the same questions over and over again (this list isn't
exactly swamped with request) but to make the discussions more focused and
hopefully instill some hope in the lonely soles out there wanting to make
their own embedded Linux but lacking the expertise to get going.
Short list of subjects:
Creating a suitable rootfs, w/ | w/o X etc.
Booting from ROM/Flash. Etherboot. I can write this one up, considering
that no one else seems willing to share their code <grin>.
More booting. Initrd, rc.d, login.
Power-down/filesystem integrity. Orderly power-downs and recovery after
not-so-orderly power failures. What needs to be writeable and what is
better left read-only. (XFS, other journalling and/or logging filesystems,
overlayfs, ROMS, cache configuration, UPS)
Networking. PPP, Ethernet, SLIP, whathaveyou.
Graphics w/o X. I know only of MicroWindows/NanoX and it/they don't
support remote hosts?
