>>> Installing sys-fs/e2fsprogs-1.41.0
* checking 86 files for package collisions
 * This package will overwrite one or more files that may belong to other
 * packages (see list below). You can use a command such as `portageq
 * owners / <filename>` to identify the installed package that owns a
 * file. If portageq reports that only one package owns a file then do
 * NOT file a bug report. A bug report is only useful if it identifies at
 * least two or more packages that are known to install the same file(s).
 * If a collision occurs and you can not explain where the file came from
 * then you should simply ignore the collision since there is not enough
 * information to determine if a real problem exists. Please do NOT file
 * a bug report at http://bugs.gentoo.org unless you report exactly which
 * two packages install the same file(s). Once again, please do NOT file
 * a bug report unless you have completely understood the above message.

I've raised the severity, as this could cause people left with a broken system
if they remove the old e2fsprogs/com_err/ss stuff and then wanna bump and have
collission-protect on.

Severity back to normal. Everybody, don't forget that you 're running ~arch.
Lars, thanks for reporting this.
