Why not like fwcf?
part=/dev/mtd/$(fgrep '"fwcf"' /proc/mtd 2>&- | sed 's/^mtd\([^:]*\):.*$/\1/')ro
This would effectively mean
+ datanr=$(fgrep '"data"' /proc/mtd 2>&- | sed 's/^mtd\([^:]*\):.*$/\1/')
if I got the line above correctly, _and_ is more easy to unserstand.
Alternatively, to save fork() and exec() time, you could do something like
+ while read line; do
+ [[ $line = *\"data\"* ]] || continue
+ line=${line#mtd}
+ datanr=${line%%:*}
+ done </proc/mtd
but I don't know if ash groks this (mksh does). In all THREE cases,
error handling if /proc isn't mounted, /proc/mtd can't be read, and
there is no "data" partition, could be added.
Please test the lines above to see if the result is correct.
