RE: UFS1 created by 5.0 is incompatible with 4.0's?
Hi, While testing the 4.0 - 5.0 upgrade path, I've created (under 5.0) a UFS1 partition and installed 4.0 onto it. After booting the 4.0 from it, kernel complained about ``numdirs is zero, try using an alternate superblock'' for / partition -- I've tried what it suggests (by fsck -b 32, etc.) but the result was always the same -- the file system was marked dirty and only read-only usable. After rebooting in 5.0, this file system was similarly unusable. Is this a bug or a feature? I've discussed this issue with Poul-Henning Kamp. You need fsck from at least 4.7.
