Re: LFS frag size

[Konrad Schroder <perseant%hhhh.org@localhost>]

We should probably use the disk sector size as the default fragment 
size, whatever that is---usually 512 (maybe still "always 512" for 
NetBSD, I haven't been paying attention).  If we had 64-bit block 
addressing in LFS, the filesystem size wouldn't be limited by the frag 
size, and I'd have changed it some time ago.

Take care,
