It does add up, but for the average user the inodes should never be an
issue.

On mine

[jeff eye_gore ~]$ df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/mapper/VolGroup00-LogVol00
                     1921984  228237 1693747   12% /
/dev/mapper/VolGroup00-LogVol01
                     7684096   36018 7648078    1% /home

[jeff eye_gore ~]$ df -m
Filesystem           1M-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                         14773      6097      7926  44% /
/dev/mapper/VolGroup00-LogVol01
                         59059     24862     31197  45% /home

Notice that / is the only filesystem using more than 1% of the inodes
here.

This is after several years of keeping a lot of the email I receive as
well as doing a lot of other stuff.

The only time I have had a problem with inodes was several years ago
when one load I did had something that went screwy and started creating
a ton of <50 byte files as an app was creating the temp file then dieing
and trying again in a loop so it left the files.  Since it never
overwrote a file, it filled up the inode table even though df -m showed
over 50% free.

I reloaded with a newer distro and never went back to find out what
actually caused the problem.
