it is ;) > Is UID24/GID24 a main line kernel feature/option? > A google search didn't turn anything of significance up. hmm, the mainline (read marcelo or andrew/linus) tree doesn't need to store context information for inodes. since 2.4.x and for 2.5/2.6 the uid/gid values are 32 bit each, so UID32/GID32 are default (no reason to limit them to 24bits). vservers and contexts require to'tag' files with context ids/tags ... and this can be done by either using some of the uid/gid bits or otherwise unused space in the on-disk inode structures ... UID24/GID24 uses 8 bit of each ID to store a total of 16bits for context information, thats it ... > Any pointers (besides to the kernel source :-) to where I can read up > on this. nope, guess my postings and explanations have to do the job for now ... > How do you keep it all in your head.
