Subject: mtd-utils: add ubihealthd to nand-utils
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7e287b563aa1043a1af54d5e2b0bd96326371732;p=openwrt%2Fstaging%2Fxback.git

mtd-utils: add ubihealthd to nand-utils

Add ubihealthd to the nand-utils package, auto-create UCI config for
each UBI device and launch the daemon on boot.

The default time interval between scrubbing a random PED is 120 seconds
which means that a fully used 128 MiB flash chip gets scrubbed in about
a day and a half. The interval can be adjusted in UCI using the
'interval' option.
