Re: Owner problems in JFFS
Using a meta file with owner information is on our TODO
list, but we don't know when it will be available.
I have added your solution as an option (-r) along with some
bugfixes in the meantime.
A patch is that also includes some improved portability changes is available
along with the complete .c file from
If you're using mkprod to build and want to use the feature,
$genjffs = "mkfs.jffs";
$genjffs = "mkfs.jffs -r";
in the mkprod script.
Don't forget to do 'make' and 'make install' in the tools directory
so that the mkfs.jffs binary is built and installed.
