Subject: Re: [RFC/RFT PATCH] cgroup: enable write permission for the group of users

agree, thanks for your replies,

To be polite, for if any user finds this thread, here is a solution, the code 
added to the daemon script

set_writeperm_usergroups() {
	local mountpoint f st_mode
	mountpoint="$(awk '$1 == "cgroup" {print $2}' "/proc/mounts")"
	if [ ! -d "${mountpoint}" ]; then
		log_warning_msg "Can't find cgroups mountpoint"
		return
	fi
	while read f; do
		if st_mode="0x$(stat --format='%a' "${f}")" && \
		[ $((${st_mode} & 0x20)) -eq 0 ]; then
			chmod g+w "${f}"
		fi
	done << EOF
$(find "${mountpoint}" -type f -perm '-u=w')
EOF
}

Regards,

Jordi Pujol
