[umlbuilder-devel] Re: problems with umlbuilder 1.40-5 and uml patched kernel 2.4.20-6

[Robert S. B. <bob...@co...>]

umlbuilder 1.40-5 does not seem to like uml patched kernel 2.4.20-6.

I saw the post about the redundant "root=" parameter being generated by
the install option of the control file and hacked it to generate a
better linux cmd line.

However, the uml kernel 2.4.20-6 kernel does not like installfs as root
filesystem.

I tried creating a sparse file (install_fs), creating a ext2 filesystem
in it, loopback mounting it, cpioing the contents of installfs into it,
modifying control to point to it, all to no avail.
