Last time I checked (5.3:ish), no. I have no clue whether it's intentional. I tried to "fix" it but never got too far (well, I gave up). If I remember correctly (which is not at all sure since this was a while ago and I did not make notes), it has something to do with the fact that the root filesystem is mounted read-only, and the appropriate flags that are required for background fsck aren't set until a dirty filesystem is mounted read/write. (But again, I may very well be mis-remembering or have misunderstood the code in the first place.) Ever since then I have started partitioning with a small root partition (a few hundre megs, up to a gig or so), a huge /usr and symlinks for /tmp and /var - as an alternative to just one huge root partition. Does anyone want to speak up as to whether the behavior *is* intentional, or just an unintentional "bug"? -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org
