Can i conclude from your words, that UML runs fine on x86 32-bit with
gcc 4.1.1 and glibc 2.4 ?

Hi,
has anybody of you gentoo-users out there (maybe Blaisorblade?) tried
UML with glibc 2.4 (which seems to be nptlonly!)?
Does it compile? Does it work?
Thanks,

Hi,
i haven't read the mailinglists some time, so i have some questions:
- What's the status of AMD64-UML-guestkernels? i mean, can i compile
them easily using vanilla sources? and do they run more or less stable?
- Do 32bit guests run stable on 64bit hosts?
- Can i easily compile a 32bit guest-k

use version 8.2 or version 9-pre9 if you want.

So i found something like:
char *dirs[] = { "TMP", "TEMP", "TMPDIR", NULL };
in arch/um/os/mem.c.
This looks, like UML is checking TMP, TEMP and TMPDIR variables. But in
my case, hmmm

Hi,
UML still seems to create its RAM-image-files in /tmp. I'd like to
change that behaviour. Perhaps i missed it, but i don't know how. (I
read --help of the kernel-binary and don't remember anything in the
kernel-config).
I'd like to mount my tmpfs to a subdir of /tmp, and then tell UML to

Hi,
just wanted to ask:
the TLS patches are already in 2.6.17-rc1, right?
If so, is there anything recommed concerning the CFLAGS?
The Gentoo Xen HOWTO told me, that i should add
"-mno-tls-direct-seg-refs" to avoid some slowdown.
See http://gentoo-wiki.com/HOWTO_Xen_and_Gentoo

hi,
it seems that the rootfs (a reiserfs) is damanged. I thought that i just
have to create the file /forcefsck so that /etc/init.d/checkroot will
run fsck on the filesystem, but the command that is executed is "fsck -C
-a -f", but that command doesn't check the filesystem if it is a
reiserfs.
I am wondering what is the best 2.6 series UML guest kernel at the
moment. Somehow I was under the impression that vanilla 2.6.10 should
be okay, but after BlaisorBlade's comment, I'm not so sure.
The best host kernel is a 2.4 + SKAS3-v3, the best guest kernel is 2.6.9-bb4.
I've not tested plain 2
Hey gang, just thought I would post this quick and dirty on how to build
gentoo from stage 1 inside of a 2.6.9-bb4 UML. BTW, the bb4 patch seems
to be really solid. I haven't run into a single issue with it thus far.
I have a script that builds a stage1-gentoo inside a chroot on the host.
