Re: Simplist way to boot only to a shell

Here are some solutions to the problem with cpio copying hard
links instead of soft links.

For users compiling their own cpio:

./configure CPPFLAGS=-DHAVE_LSTAT=1 [other_options]

For users of gentoo, emerge cpio-2.6-r2

This solves the problem of the error of no space
left from cpio, while running pxesconfig.
