There are many important things that a 2.0 vintage system may need to
upgrade before upgrading to 2.4. These changes are documented in
Docmentation/Changes in the kernel source tree. The following list is
a summary of the Changes files from 2.2 and 2.4. Note, these are the
minimum required versions. Later versions can be used, but earlier ones
have known bugs that may result in improper behavior. Also, if you don't
use a particular package, no reason to upgrade it.
From 2.0 -> 2.2 Changes summary:
- Kernel modutils 2.1.121 ; insmod -V
- Gnu C 2.7.2.3 ; gcc --version
- Binutils 2.8.1.0.23 ; ld -v
- Linux libc5 C Library 5.4.46 ; ls -l /lib/libc*
- Linux libc6 C Library 2.0.7pre6 ; ls -l /lib/libc*
- Dynamic Linker (ld.so) 1.9.9 ; ldd --version or ldd -v
- Linux C++ Library 2.7.2.8 ; ls -l /usr/lib/libg++.so.*
- Procps 2.0.3 ; ps --version
- Procinfo 16 ; procinfo -v
- Psmisc 17 ; pstree -V
- Net-tools 1.52 ; hostname -V
- Loadlin 1.6a
- Sh-utils 1.16 ; basename --v
- Autofs 3.1.3 ; automount --version
- NFS 2.2beta40 ; showmount --version
- Bash 1.14.7 ; bash -version
- Ncpfs 2.2.0 ; ncpmount -v
- Pcmcia-cs 3.0.14 ; cardmgr -V
- PPP 2.3.10 ; pppd --version
- Util-linux 2.9z ; chsh -v
- isdn4k-utils v3.1beta7 ; isdnctrl 2>&1|grep version
From 2.2 -> 2.4 Changes summary:
o binutils 2.9.1.0.22 # ld -v
o util-linux 2.10g # chsh -v
o modutils 2.3.10 # insmod -V
o e2fsprogs 1.18 # /sbin/tune2fs --version
o pcmcia-cs 3.1.13 # cardmgr -V
o PPP 2.4.0b1 # pppd --version
o isdn4k-utils 3.1beta7 # isdnctrl 2>&1|grep version
All these are backwards compatable with 2.0 kernels, so you can play
with 2.0, 2.2, and 2.4 all on the same system with one set of binaries. 2.2 and 2.4 will compile
with correctly with gcc 2.95.2 and egcs 1.1.2, while 2.0 will not. More
information, including where to download, can be found in the Changes
file itself.
Hope I saved someone some grief,
