| |
Has anybody looked seriously at supporting 32 bit UIDs on Linux? We'd really like to make Linux a commodity at Umich, but with a user base of about 100,000, high UIDs are an absolute requirement. I've only just started looking at this, but scanning the include files, it would appear that some platforms already support high UIDs, but not i386.
Just for grins, I tried changing the typedef in linux/types.h and recompiling the kernel. Wouldn't even boot. Then I noticed that the uid and gid fields in ext2 inodes are 16 bits. So it seems like this is a project, not than a hack. (This was on 2.0.35.)
There's enough interest in this on campus that we can throw some resources at it. If no one else has this one, we could probably do it. If someone is doing it, how do I get in touch? Comments? Advice
