Permissions issues
I'm hoping this is a pretty simple question. I have a problem were memebers of a group can't delete or overwrite a file. The box is setup several users all part of the same group. Now default umask is 002. The problem I run into is there are processes that add to, del, and over write files. Now if I start this processes and own the files everything works great, but if someone else starts that processes and I own the files it 's hit and miss. Sometimes is works and sometimes there are permissions errors. Any ideas on what could cause this? and yes the processes does have to be ran by other users and its just not practical to change the file owner everytime some else starts the processes nor is it good to set default permissions to rwxrwxrw.
Thanks

cgconfigparser
CGCONFIGPARSER(8) libcgroup Manual CGCONFIGPARSER(8)
NAME
cgconfigparser - setup control group file system
SYNOPSIS
cgconfigparser [-h] [-l <filename>] [-L <directory>] [...]
OPTIONS
-h, --help
Displays help.
-l, --load=FILE
Parses the control groups configuration file Sets up the control group file system defined by the configuration file and mounts
mount points defined by the configuration file. The format of the file is described in cgconfig.conf. This option can be used mul-
tiple times and can be mixed with -L option.
-L, --load-directory=DIR
Finds all files in given directory and parses them in alphabetical order like they were specified by -l option. This option can be
used multiple times and can be mixed with -l option.
-a <agid>:<auid>
defines the default owner of the rest of the defined control group's files. These users are allowed to set subsystem parameters and
create subgroups. The default value is the same as has the parent cgroup.
-d, --dperm=mode
sets the default permissions of a control groups directory. The permissions needs to be specified as octal numbers e.g. -d 775.
-f, --fperm=mode
sets the default permissions of the control group files. The permissions needs to be specified as octal numbers e.g. -f 775. The
value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and others permis-
sions to the owners permissions).
-s, --tperm=mode
sets the default permissions of the control group tasks files. The permissions needs to be specified as octal numbers e.g. -f 775.
The value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and others per-
missions to the owners permissions).
-t <tuid>:<tgid>
defines the default owner of tasks file of the defined control group. I.e. this user and members of this group have write access to
the file.
