Traditionally the FreeBSD tree was placed in /pub/FreeBSD
because that's the location where sysinstall looks for the
installation sets and packages. It can be a symlink, too.
You can find the set of paths where sysinstall looks for
the installation data on FTP servers at the beginning of
the file src/usr.sbin/sysinstall/ftp.c (reformatted):
/* List of sub directories to look for under a given FTP server. */
const char *ftp_dirs[] = {
".",
"releases/"MACHINE,
"snapshots/"MACHINE,
"pub/FreeBSD",
"pub/FreeBSD/releases/"MACHINE,
"pub/FreeBSD/snapshots/"MACHINE,
NULL
};
where MACHINE is "i386", "amd64" etc. The first of those
directories that does exists and contains a subdirectory
naming the desired release (e.g. 8.2-RELEASE) will be used
to download the installation data. Typically, that's the
second to last entry: /pub/FreeBSD/releases/8.2-RELEASE
A similar algorithm is used to locate packages, distfiles
for ports, documentation files and possibly other data.
There are some mirrors that have the FreeBSD data somewhere
else, including /FreeBSD, for example. If one of those is
used for installation with sysinstall, the FTP path has to
be changed manually in the options screen of sysinstall.
I think all of the "official" mirrors (i.e. those who can
be found in the .freebsd.org domain) use /pub/FreeBSD, so
it works with sysinstall out of the box, without having to
modify any options. As mentioned above, it can also be a
symlink.
Best regards
Oliver
