Subject: [yocto] Which filesystem for target?
A bit of an open-ended question, but...
Which is the 'best' filesystem to use for an embedded device that's
using a CF card?
It needs to survive loss-of-power, have a RO root filesystem, allow
user configuration data to persist and (ideally) only use 'Busybox'
This seems to imply the use of a partition for booting (mount RO) and
a second partition or a loop-device on the boot partition for
I would normally go for ext3, but Busybox doesn't support it (afaik).
The Busybox tune2fs also only supports -L, so I can't stop 'disk needs
checking after <n> mounts' messages.
Is btrfs a suitable alternative?
