- This is probably a limit in the rootdisks - I think the /dev/hdaX
- entries only go as far as /dev/hda8. The fix is very simple: just
- create the needed special files with mknod:
-
- # mknod /dev/hda9 b 3 9
- # mknod /dev/hda10 b 3 10
-
- etc. By doing a "ls -l /dev/hd*" you see the device numbers, and the
- setup should be pretty obvious when reading them.

- The problem is the default number of rows that linux uses: I have
- stupidly set the value to 25 instead of the normal 24 for a vt100
- terminal. The fix should once more be very simple: do a
-
- # stty rows 24 columns 80
-
- or
-
- # eval `resize`
-
- on the line before staring up.

-
- The man-pages for most GNU things are in the sources - for some binaries
- (like fsck) no man page is available, and you have to read the actual
- source files.

-
- This is usually a mark of a bad compile of the shell, but I haven't seen
- it (but I use my own port of most relatively simple things). Don't know
- of any simple fix.
