As it's Sunday, here's an odd little thing.
Not long ago, while booting this machine, four ext3 partitions
needed checks on remount count reaching zero. They had been set to
23, 24, 25 and 26 mounts. (I didn't choose the numbers; they were
allocated at the time I was creating the file system.)
Now, this box does get rebooted, but hardly 23 x 24 x 25 x 26 =
358,800 times all told. At, say, two reboots per day, that would
take rather a long time: a little under 500 years if my arithmetic
is working.
I think you're confused. 23 means a check each 23 mounts. With 2
mounts per day, that's a check every 12 days for the first and second
disk.
I think the point is that 23, 24, 25, 26 are relatively prime so that,
if N is initially zero, it takes 23x24x25x26 increments initially for (N
mod 23), ..., (N mod 26) to all again be zero.
Why would it matter if they're all zero or not?
