Filesystems

QNX SDP8.0Migrating to QNX OS 8.0Developer

Filesystem ownership and permissions

The following options that are used with devb-* drivers as a command-line option and mount -o have been removed: mntperms, mntuid, mntgid.

Use the following options instead of mntperms:

For filesystems that do not have real POSIX permissions (e.g., FAT), partitions, block devices, and QTD, via the attributes dperms=, fperms=, perms=, uid=, gid=.
For filesystems with a real root directory (qnx6fs, ext2fs, qcfs, squashfs):
- set the mountpoint permissions, either in the buildfile (qnx6fs, qcfs, squashfs) or via the command chmod mountpoint (qnx6fs, ext2fs, qcfs, squashfs), and
- set the mountpoint ownership with the chmod file or chown file command, where file is the path where the filesystem is mounted.

For other items that are discontinued or planned to be discontinued, go to the QNX Software Development Platform 8.0 Deprecation and Discontinuation Notice.
