Re: [irlp-embedded] Re: Flash_sync
- No, a standard embedded system (like yours) uses the flash drive as a
read only configuration for setup of the node at boot time. It loads the
entire filesystem into RAM, and it runs there. This makes the node
immune to power bumps, sudden resets, drive wear, etc.
What Alan has asked for is a basically an embedded node with a full hard
drive in it, however the hard drive has no moving parts. What Alan gains
is the ability to add some extra software onto his node, but what he
loses is the reliability and compact nature of the embedded file system.
If the power drops out, there is a chance, albeit small, that his node
will be corrupted. The same is not true of the standard embedded setup.
