I used to have different gentoo-source on a server for all Gentoo systems. That was not good. Building of kernel was very slow. And sometimes the system hang. 
I still keep distfiles on the server, but linux source lives only on tempary space. This is how I upgrade now:
In /etc/fstab: | Code: | tmpfs /tmp tmpfs size=4g,nosuid,nodev 0 0
tmpfs /var/tmp tmpfs size=4g,nosuid,nodev 0 0
tmpfs /usr/src tmpfs size=4g,nosuid,nodev 0 0 |
Command to build new kernel: | Code: | time (emerge -1 gentoo-sources;genkernel --menuconfig --install --integrated-initramfs --kernel-config=/proc/config.gz all)
Calculating dependencies... done!
