mount_ifs
Mount an image filesystem (QNX)
Syntax:
mount_ifs [-bT] [-C size] [-d dll [,arg...]] -f filename [-k keyfile] -m mountpoint
[-o trusted] [-v[v]...]
Runs on:
QNX Neutrino
Options:
- -b
- Daemonize and return before the transfer of the data. By default mount_ifs daemonizes itself after.
- -C size
- The buffer/chunk size. The default is 64 KB.
- -d dll [,arg...]
- Load this DLL and pass it the signature_provider() function (see
Verification
for more information). Optionally, you can specify additional arguments to the provider function. - -f filename
- The name of the file containing an image filesystem.
- -k keyfile
- The PEM file containing the public key.
- -m mountpoint
- Where the device is to be mounted on your system.
- -o trusted
- Mount a non-boot IFS as trusted.
- -T
- Create a second thread to handle the decompression in parallel. You need to use this only if you have a compressed IFS image.
- -v[v]...
- Be verbose; more
vcharacters cause more verbosity.
Description:
The mount_ifs utility mounts an image filesystem at the specified mountpoint, decompressing the filesystem if it's compressed. It's similar to using mount with the -t ifs option, but it uses direct I/O (if supported) to load the IFS image from a block device into memory, and then mounts the IFS. The utility allocates the memory and daemonizes itself, and supports the same compression algorithms as mkifs.
This utility supports image filesystems that are formatted as ELF or binary, but not as SREC.
This program uses the OpenSSL library for cryptography services.
Verification
The IFS image can be digitally verified using an RSA-SHA256 signature before it is mounted. To
enable verification, provide both the name of a PEM file containing the RSA public key
(-k option) and the name of a DLL with a callout function acting as a signature
provider (-d option). The DLL must contain the following function:
int signature_provider(const char *filename, const char *arg,
size_t siglen, unsigned char *sigbuf);Page updated:
