Hi, All,Why the mount point has to be standardized ?
We've been having a discussion as to what would be the right place to
mount the cgroup filesystem. Jan has been proactively looking into
this. The FHS has no recommendation since cgroup filesystem came in
The options are
3. Some place under /sys
The problem with (2) is that it is quite non-standard and pollutes the
root directory. (3) requires some basic support to create a directory
for cgroup under /sys. (1) seems the most obvious choice since cpusets
were mounted under /dev/cpuset, but /dev is controlled by udev.
Given the three choices or any other suggestions, is there a general
preference as to where we can mount it? The goal is to standardize
the mount point (if possible).
The mount point does not need to be set into stone so everybody *must*
use it. I, as Fedora packager, just need some default place where to
mount it, so applications which need to create/manage groups work
without any (potentially dumb) user assistance. Of course, advanced
admin can change the settings and move the groups anywhere, applications
still need to parse /proc/mounts or use appropriate library like libcgroup.
