[gentoo-user] emerge hints needed

[Bill Kenworthy]

Some time back I saw someone mention a way to get emerge to install an
ebuild with a bad digest - man emerge shows nothing so can someone give
me a hint.  It was much easier than going down the ebuild path.

Also, I am in the process of rescuing a system from the
e2fs/util-linux/device-mapper snafu and find that now I have it booted
re-emerging util-linux wont overwrite the files I manually installed to
replace the missing ones - necessitating manually rm'ing some 50 or so
files - is there a way to force emerge to ignore file collisions and
just overwrite them in this circumstance?
