According to <method@zimage.com>: > Are 32-bit UIDs a kernel issue or a glibc issue? Any ideas >when Linux will support 64-bit UIDs?
I think UIDs are currently 16 bits, not 32. Since 32 bit uids would be enough for one third of the planet to have an account on one system, I think that 32 bits is plenty - we don't need the extra performance hit on 32 bit machines that 64 bit UIDs would take.
I think both the kernel and the libc have ideas about what size a uid_t is. There was some discussion here a while back about making UIDs (and I assume GIDs as well) 32 bits - did anything ever come of that? -- Chris Adams - cadams@ro.com System Administrator - Renaissance Internet Services I don't speak for anybody but myself - that's enough trouble.
