Hi all,
i would want to ask you how to remount secondary ifs as r/w.
When the the primary if boot its mounted in "/" but that is not visible in fstab and cant be remounted with mount -u.
Then the secondary ifs is mounted in "/" too and again not visible in fstab and can't be remounted.

This is harman-becker multimedia unit with nVidia Tegra running QNX.

I've tried to mount it by specifing the offset but that was not possible to or dont use the right parameters.

in /dev i see 
fs0
fs0p0
fs0p1
fs0p2
fs0p3

ifs-root and secondary ifs as well as the IPL are on fs0p0.

If i try to rebuild that secondary ifs i get strange results, 
i build the ifs successfully with mkifs, and then restore it.
If i compare the files one by one then i see that shared library and some of the executable files are not 100% match 
although i used the same file build the image. They are modified so the usage info is reversed.
If i specify [+raw] and use [perms=+x] then the files are 1:1 but they are not good for the unit and cant be started 
regardless of the fact that they are with 777 perms.

If you want more info i will provide.

Any help will be appreciated.
Kind regards.
