Here’s how to store portage in a file. Ext2/3 filesystems on a 2GB partition do not have enough inodes to store the , use reiserfs, for example.

/ # dd if=/dev/null of=/usr/portage.disk bs=1M count=0 seek=2048
/ # mkreiserfs -f /usr/portage.disk
/ # mkdir -p /usr/portage
/ # mount /usr/portage.disk /usr/portage -o loop,notail,noatime,nodev

The portage file is limited to 2GBs, hence we have to move the distfiles directory (default: /usr/portage/distfiles). This can be done either by editing make.conf and specify a new location or creating a distfiles directory somewhere else and have /usr/portage/distfiles link to it:

/ # mkdir -p /var/tmp/portage/distfiles
/ # cd /usr/portage
/usr/portage # ln -s /var/tmp/portage/distfiles

Finally, add a line to /etc/fstab to have the portage disk mounted at boot time:

/usr/portage.disk    /usr/portage    reiserfs    loop,notail,noatime,nodev,noexec 0 0

Done.

ok, so you finally do the GCC 4.1.1 update that is basically forced upon us and end up with:

# emerge -uv gcc

It turns out that the “HARDENED” gcc 3.4.6 cannot compile gcc 4.1.1.

Solution: re-emerge the old gcc without the HARDENED flag

# emerge --oneshot =gcc-3.4.6-r1
# env-update && source /etc/profile

and then, finally

# emerge --auv gcc

Happy compiling!
