Notes on Updating to Kernel 2.2.x
Mon Jan 31 19:26:25 MYT 2000
Here are some notes that I've found useful, in helping my Linux system
work in a much nicer way, ever since I installed Kernel 2.2.12-20. The
distribution of my choice is RedHat 6.1 currently, and just in case of
problems, make sure you're running the latest version of RedHat.
These are about everything I found quirky with the newer kernel. There
are newer development kernels out, but for a stable box for daily use,
I shant use them.
/etc/printcap has to be changed to use /dev/lp0 instead of /dev/lp1. It
has been said that obsolete DOS numbering was to be done away with, and
Linux wants to begin with 0 instead of 1.
In RedHat, the printer may not print, and even printtool cannot fix it.
Adding a line in the /etc/conf.modules that says alias parport_lowlevel
parport_pc will do the trick it seems.
For modems, et al, that utilise the serial port, /dev/ttySx (where x is
an integer) is the new standard. /dev/cuax is no longer in use, so the
kernel must be updated to use the newer /dev/ttySx.
/dev/ttypx has been dropped in the newer kernel. It has been replaced with
/dev/ptyx and /dev/ttyx, hence forcing creating newer entries.
The once partition limit for swap being limited to 128MB has been removed.
The swap file can be bigger now, but util-linux's mount and mkswap has
to be updated. However, if you have more than 128MB physical RAM, the chance
of swap usage is minimal (I have 160MB and I never use any swap.)
Ctrl+Alt+Del reverts to a cold boot, if run by any user.
