[Pkg-sysvinit-devel] Bug#457783: Mount spufs on systems machines with the Cell CPU?

[Petter Reinholdtsen]

Package: initscripts
Version: 2.86.ds1-38
Severity: wishlist

While browsing the ubuntu patch for sysvinit version
2.86.ds1-14.1ubuntu32, I came across a change to support spufs.  The
change consist of changes in debian/changelog, debian/control
debian/initscripts/etc/init.d/mountkernfs.sh and
debian/initscripts/postinst.

I find documentation on the spufs on
<URL: http://www.mjmwired.net/kernel/Documentation/filesystems/spufs.txt >,
and it is related to the Cell microprocessor.  I am not sure if this
mounting belong in the initscripts package, or if it should be part of
some Cell specific package.  I am adding this bug report to track the
issue and collect feedback.  I'm not sure how important it is to mount
the file system, nor what it is used for.

These are the changes implemented in Ubuntu.

sysvinit (2.86.ds1-14.1ubuntu19) gutsy; urgency=low

  * initscripts:
    - Create mountpoint for spufs on systems which support it.
    - mountkernfs.sh: Mount spufs on systems which support it.
    - Add dependency on passwd.

debian/initscripts/etc/init.d/mountkernfs.sh

  # Mount spufs, if Cell Broadband processor is detected
  if mountpoint -q /proc && grep -qs '^cpu.*Cell' /proc/cpuinfo; then
    mkdir -p /spu
    domount spufs "" /spu -ogid=spu
  fi

debian/initscripts/postinst

  #
  # Create mount point for spufs, and create spu system group
  #
  if mountpoint -q /proc && grep -qs '^cpu.*Cell' /proc/cpuinfo; then
	if ! getent group spu >/dev/null; then
		# the adduser package is priority important; cannot use addgroup
		#addgroup --system spu
		groupadd -K GID_MAX=1000 spu
	fi
	mkdir -p /spu
	if ! mountpoint -q /spu; then
		mount -t spufs -ogid=spu spufs /spu
	fi
  fi

debian/control

  Add passwd to the depends of initscripts.

Happy hacking,
