Hi,

I'm booting a liveusb with SystemRescueCD to install Gentoo (that's because the Gentoo Minimal Install ISO can't boot with UEFI and the Gentoo LiveDVD is too big for my purposes).
Anyway, SysRescCD is a third-party Gentoo system.

I booted via UEFI and got to the Grub menu. I selected the first default boot option which loads the rescue64 64-bit kernel image.

However, I get the following results when trying to check if I have a 32 or 64-bit system:

Code:

# getconf LONG_BIT
32
# uname -m
x86_64
# arch
x86_64
# file /sbin/init
/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, stripped


Does this mean the kernel is 64-bit but all the applications are 32-bit?

If I boot "gentoo64" from the Gentoo Minimal ISO, I get all-64bit results, ie., getconf LONG_BIT=64.

Can anyone please let me know if I can install a Gentoo 64-bit multi-lib system on a HDD from this SysRescCD (latest release)?

You are using a x86_64 kernel.Yes you can use this for a 64-bit multilib install. systemrescuecd is many peoples preferred method for installing gentoo

Hi!,

The system in systemrescuecd is 32 bits, and the kernel is 64 or 32 bits, depending if the bootloader detects a 32 or 64 bits processor.
UEFI boot chooses automatically 64 bits if I remember.

So, you can install a 64 bits system without any problem with SystemRescueCD (what I use for years, for 32 and 64 systems).

You only have to download a 64 bits stage 3 and chroot into it.

I did that but it seems to be failing on something that has apparently nothing to do with this topic.
It's the first time I try to use a non-official-Gentoo live system to install Gentoo on a HDD.

I'm getting this:

Code:

For firewall reasons I need to do a webrsync.
I don't recall having this issue with the Gentoo Minmal Install ISO.
The portage files are accessible but the command fails. Maybe it's not constructing the right URL. Odd...

[EDIT] I'm running this within chroot, of course.

Please check this folder, and its contents

Code:
/etc/portage/repos.conf

Roman: what do you want Vieri to check there? What do you expect is incorrect?

Vieri: is an unprivileged user otherwise able to use the network in that environment? Is /etc/resolv.conf world readable and configured to use a nameserver that works? Is the network up, with a valid default route? Check with ls -l /etc/resolv.conf ; cat -n /etc/resolv.conf ; ifconfig -a ; route.

I use webrsync too, for security reasons (the main tree is unsigned). Sometimes you just get a bad mirror in the rotation. Doing GENTOO_MIRRORS=foo emerge-webrsync instead of using the default should work.

Here's how to test the mirror manually:
Code:
curl -I $(portageq gentoo_mirrors | cut -f1 -d' ')/snapshots/portage-latest.tar.xz{,.md5sum,.gpgsig}

Xavier, booting SysRescCD from Legacy BIOS shows the syslinux boot menu which uses a module to autodetect if the machine can run 64 bit or not. However, booting from UEFI loads a GRUB menu and all its entries are for 64 bits (no detection).

OK, so it seems I can install a 64-bit system (chrooting to it) even if the live system has 32-bit binaries, as long as it boots a 64-bit kernel.

Hu, thanks, you're right. I didn't "cp -L" resolv.conf from live to jail root. That's because I'm used tp the Gentoo Minimal Install where /etc/resolv.conf is not a symlink. SysRescCD has a symlink for that file.
My bad... However, emerge-webrsync's output made me think there was a problem with the remote repository because of the message "snapshot was not found"...
It would have been clearer if it had said something like "cannot resolve" or "cannot connect".

Anyway, thanks!

Thanks for the tip. I'll keep that in mind. In my case though, I had an issue with /etc/resolv.conf.
