I need to do some testing with kernels as far back as 2.6.25. I've
currently got a Gentoo box that can build and run kernels ranging from
3.14.rc2 to 2.6.32. There are various gcc and make issues which have
been successfully dealt with, but now I'm stuck on DEVTMPFS.
Prior to 2.6.32 DEVTMPFS isn't available, so even though I can build
and boot a 2.6.25 kernel, udev craps out.
There are plenty of spare paritions to play with, so doing a Linux
install to test with kernels older than 2.6.32 is no problem.
I'm wondering if instead of downloading an old Ubuntu or Fedora DVD,
is there any way to install an "old" version of Gentoo that will work
with pre-DEVTMPFS kernels?
Do you actually need udev?
Good question -- I probably don't. For the testing in question I
should be able to live with a static /dev directory. Is there any
documentation on doing a Gentoo install without udev?
If you can get away with just having a static /dev with pre-created
device nodes, that would be the simplest solution.
It would probably be asking for too much to try to toggle between udev
and static /dev at boot time in a single installation...
I remember that it was possible to toggle before openrc was introduced.
As things stand now, you would probably have to replace sys-fs/udev with
sys-fs/static-dev (which satisfies virtual/dev-manager). NeddySeagoon
mentions it here:
http://dev.gentoo.org/~neddyseagoon/Old_Fashioned_Gentoo_2.xml
He also describes its coverage as being incomplete. In that case, this
may help to populate /dev to a reasonable extent:
