Source tree and ports tree on Linux file system?

[Thomas Mueller]

Can FreeBSD build from source with source tree on Linux ext2fs partition, and subsequently compile ports from such partition, using USB-stick installation of FreeBSD 9.x?

That would be useful if FreeBSD Ethernet driver doesn't work.

This is mainly a matter of curiosity, since I used a NetBSD-current amd64 installation, where the Ethernet driver worked, with subversion built from pkgsrc.

In this latter case, file system was ffsv2 aka UFS2.
