[gentoo-user] udev-197 vs udev-200??

[Tanstaafl <tanstaafl@libertytrek.org>]

Ok, I don't understand this...

Why is it that when I comment out the package.mask entries for udev:

#>=sys-fs/udev-181
#>=virtual/udev-181

emerge -pvuND world shows updates to udev-197, with no mention of 
udev-200, but...

when I uncomment them:

 >=sys-fs/udev-181
 >=virtual/udev-181

emerge -pvuDN world shows updates to BOTH virtual/udev-197-r2 *and* 
udev-200, with strange Blockers referencing udev-186???

That seems bizarre...
