Errata

chkfsys
This utility doesn't prevent itself from operating when files are open for writing on the drive.
crontab
If you want the output from your commands, redirect it to a file.
devf-*
  • If you specify the -V option, the driver displays the filesystem and MTD version information, and then exits.
  • The bwidth and ileave values for the -s option must be powers of 2, but you don't specify them as powers of 2. For example, if the width of the data bus is 8, specify a bwidth of 8, not 3 (for 23).
etfsctl
Existing IPLs and bootloaders can't boot from an image in an embedded transaction filesystem.
find
We've corrected the description of the %a and %A formatting codes.
lpr
The printer argument to the -P option must be a printer name that's defined in /etc/printcap.
mkifs
  • You can use mkifs to build nonbootable images. For an example, see the Making Multiple Images technote.
  • You have to specify both image and ram file attributes if you want to create the image in ROM/FLASH; otherwise the process manager assumes that the image is in RAM.
  • The mkifs utilities no longer strips the QNX_usage (usage message), and QNX_info (build properties) sections by default. You can use the -s option to specify additional sections not to be stripped.
  • Startup code can be decompressed in place.
  • Attributes that you specify with attr=image_attribute in the bootfile are processed after the -l ("el") command-line options and the buildfile, but you normally use the ? prefix on the image_attribute, so that it doesn't override anything explicitly set by the -l option or the buildfile.
ntpd
After the machine has synchronized to a NTP server, the operating system time gets synchronized and corrected from time to time. This doesn't set the hardware clock; you can use the rtc utility to set the time on the chip.
pidin
If you use pidin thread or pidin -F%h to display the thread names, and a thread doesn't have a name, pidin displays the thread's ID (tid) instead.
procnto*
  • The example implied that using the -p option disables preemption; it actually disables preemption only in the kernel code.
  • Specifying the -as option on SH platforms is the same as specifying -ad, not -ae.
random
If an error occurs, random sends a message to slogger, not to stderr.
renice
This utility changes the priority of all the threads in the specified process or processes.
slogger
We've corrected the description of /dev/console, what happens when multiple applications open /dev/slog for reading, and the example of alternating between files.
startup-*
The -R option can include an alignment as well as a size.
