Doesn't this work for you?
Code:

# emerge /usr/portage/sys-boot/silo-1.3.1-r1.ebuild

See Portage Manual, section "Merging Packages".

Good luck!

Are you sure you need to downgrade? silo-1.4.4 should work for you on U2.

But if you really need to downgrade, something like the following should work, assuming
your silo.conf is in /boot:

Code:

emerge =sys-boot/silo-1.3.1-r1
silo -C /boot/silo.conf -f


You would do this as two commands while logged in as root after (or well into) your install,
because you need /boot to be on the disk you are going to boot from.

Best is to do the install without doing this. As long as you can boot from the CD (or whereever you are
booting from), you don't have to worry about it unless you need it, and on U2, you shouldn't.

If you want to know how silo works, look at http://www.sparc-boot.org and the flow
diagram at http://www.sparc-boot.org/how.html

I hope this is of some use.
Regards,

Don't do that. It causes all sorts of horrid breakages. Instead, either:
Code:
emerge \<sys-boot/silo-1.4

or add
Code:
>=sys-boot/silo-1.4
to /etc/portage/package.mask

Hi ciaranm,

Are these "horrid breakages" specific to sparc (or even silo) or is the example given in the documentation not good? (If so, I think it should be changed.)

Cheers

Well... emerge /path/to/ebuild has its uses. However, it shouldn't be used for day to day things or for getting a specific version. The issue being, emerge /path/to/ebuild doesn't update world or virtuals, so in effect portage doesn't think the package in question has been installed.

They do. Or rather, most of them do. If anyone knew why a few of them b0rked we'd be able to fix it.
