There is no possibility to do the first solution.
The second, regarding drive mounting, is it ram drive?
No, loopback filesystem.
If so, How to mount it ?
mount -o loop <filename> <mount point>
To create the file, first create a suitably-sized file with e.g.:
dd if=/dev/zero out=loopfile.dat bs=1m count=100 #100Mb
then create a filesystem on it with:
mke2fs -F loopfile.dat
Anyway, I am looking for a way to make my file system read only.
That will surely, be the best solution.
My application is writing into certain folder, not on the physically /
File system, So I can make the / FS read only, Do you have an idea how
can I do that ?
Normally, directories which need to be writable, e.g. /var and /tmp,
would use separate partitions. Those partitions would be writable (but
probably using the noexec and nodev options), but the root filesystem
would be read-only.
The most common issue with making the root filesystem read-only is that
"mount" tries to write to /etc/mtab, which will fail. Either use the -n
option to mount or recompile mount to use e.g. /var/run/mtab instead.
