hi below is sysvinit script for handling tcng-script .... please excuse my bad bash skils, correct me where i'm doing stupid things :")
what is left... many things, if i have time i will implement them too :
- start [devices] - and then correct handling of service lock files i.e. per device lock file
- stats blah ... - all ideas are welcome !!
- test or some such, i mean the ability to use temprary config file and restore back original if something
goes wrong.. ideas? Or something like last-good-known config/s
And u normaly start this on sysv system like this :
service tcng [command] [subcommands|devices]
Don't forget to set correct paths to "tc, tcc and tcng-config"....
PS. probably the script can be easly tweaked to work also as pure TC -service !!
