jails jail / linuxator /gentoo

[Alain De Vos]

Would it be possible to:
Create a jail
In this jail run the linuxator
Under this linuxator install gentoo-linux as operating system ?

Yes, but it with some issues likes portage not work.

mkfifo: cannot set permissions of '/var/tmp/portage/app-misc/screenfetch-3.9.1/temp/multijob.rbwYPC': Bad file descriptor

Maybe you need Google translate.

I see. A linux special file on a freebsd os tend to be difficult to make...

Probably.
1. see the jail settings (allow.mount.$LOTS) you need so that the linux installer has the permissions needed. I have documented this for Ubuntu here: https://github.com/msimerson/Mail-Toaster-6/wiki/Linux-Jails
2. Refer to the debootstrap scripts. They have within case statements where they make the linux special files and nodes differently on debian/ubuntu vs FreeBSD.
3. If that's not enough, there might be some patching needed for portage.

Now I test everthing is fine

just


# fetch http://book.bsdcn.org/gentoo.sh

There will be stuff that's not going to work. The linux emulation layer simply isn't Linux and can't provide a full blown Linux kernel.

I remember running Arch Linux in linux jail a while back - everything worked until I attempted to compile and create binary packages for pacman. Thats where fakeroot fell over due to missing primitives and system calls, for example.

It will work for a lot of things but expect issues.
