any pointers (with limits)?

Hmm, I had a browse through the kernel source for a while but didn't find anything definite. What I do know is that you should endeavour to keep the length no greater than 8. Up to 15 is probably ok as well on modern kernels, and group names longer than 15 is getting a bit silly.

Sorry no to have anything more precise.
