Description Curtis Doty 2001-04-27 07:26:01 UTC

It appears this rpm does not check for the presense of kernel 2.4, thus 
allowing me to install with kernel 2.2. Yet it gets rather grumpy due to 
the use of -u in the init script.

Comment 1 Daniel Roesen 2001-04-27 08:49:51 UTC

There is no problem with using -u with current 2.2 kernels. The only problem I
saw was that BIND disables IPv6 because it detects kernel<->libc structure
discrepancies.

Comment 2 Curtis Doty 2001-04-27 17:42:24 UTC

My config...

$ rpm -q kernel bind bind-utils
kernel-2.2.16-22
bind-9.1.0-10
bind-utils-9.1.0-10

and from the syslog:
named: named startup succeeded
named[2203]: starting BIND 9.1.0
named: named:
named: -u not supported on Linux kernels older than 2.3.99-pre3 when using 
threads
named: named startup failed

Workaround was hack -u out of the init script, change some permissions, and run 
as root. Ugh!

Comment 3 Daniel Roesen 2001-04-27 17:56:59 UTC

I said "with current 2.2 kernels" which 2.2.16 doesn't qualify as. IIRC the
change is in 2.2.18 or at least 2.2.19.

Comment 4 Curtis Doty 2001-04-27 18:24:36 UTC

I'm stuck with 2.2.16 due to the !%$! closed source module for a Promise 
FastTrak controller. However, I would have avoided this had the specfile 
included a Requires: kernel >= 2.2.18

Comment 5 Bernhard Rosenkraenzer 2001-04-27 21:42:30 UTC

We don't want the dependency in precisely because you can run without "-u 
named".

You should really really update to kernel 2.2.18 or higher though, 2.2.18 
fixes a local root exploit.
Since there are not that many changes between 2.2.16 and 2.2.19, are you sure 
you can't just insmod -f their module?
