The virtuals management is unclear to me. Or (better) I understand something that doesn't work. 
An example should be the best to explain.
I want to switch from MySQL to MariaDB.
| # emerge -C dev-db/mysql: | | bla bla bla |
| $ cat /etc/portage/make.profile/virtuals: | # MariaDB
virtual/mysql dev-db/mariadb |
| $ grep mariadb /etc/portage/package.accept_keywords: | | dev-db/mariadb |
| $ emerge -p virtual/mysql: | These are the packages that would be merged, in order:
Calculating dependencies ... done!
[ebuild N ] dev-db/mysql-5.1.62-r1 USE="berkdb community perl ssl -big-tables -cluster -debug -embedded -extraengine -latin1 -max-idx-128 -minimal -pbxt -profiling (-selinux) -static -test -xtradb" 0 kB
[ebuild R ] virtual/mysql-5.1 USE="-embedded -minimal -static" 0 kB
Total: 2 packages (1 new, 1 reinstall), Size of downloads: 0 kB |
What's wrong?
I'm unable to drive the portage behaviour about.
The workaround works fine.
| # rm /etc/portage/make.profile/virtuals: | | rm: rimuovere file regolare "/etc/portage/make.profile/virtuals"? y |
| # emerge -1 dev-db/mariadb: | | bla bla bla |
| $ emerge -p virtual/mysql: | These are the packages that would be merged, in order:
Calculating dependencies ... done!
[ebuild R ] virtual/mysql-5.1 USE="-embedded -minimal -static" 0 kB
Total: 1 package (1 reinstall), Size of downloads: 0 kB |

Here are my references...
| Code: | /etc/make.profile/ or /etc/portage/make.profile/
This is usually just a symlink to the correct profile in /usr/portage/profiles/. Since it is part of the portage
tree, it may easily be updated/regenerated by running `emerge --sync`. It defines what a profile is (usually arch
specific stuff). If you need a custom profile, then you should make your own /etc/make.profile/ directory and
populate it. However, if you just wish to override some settings, use /etc/portage/profile/ (it supports all of
the same file types that /etc/make.profile/ does, except parent). Do NOT edit the settings in /etc/make.profile/
because they WILL be lost with the next `emerge --sync`. If both /etc/make.profile/ and /etc/portage/make.profile/
exist, then /etc/make.profile/ will be preferred.
...
virtuals
This controls what packages will provide a virtual by default. For example, if a package needs to send
e-mail, it will need virtual/mta. In the absence of a package that provides virtual/mta (like qmail, send‐
mail, postfix, etc...), portage will look here to see what package to use. In this case, Gentoo uses
net-mail/ssmtp as the default (as defined in the virtuals file) because it's the package that does the very
bare minimum to send e-mail.
Format:
- comments begin with # (no inline comments)
- one virtual and DEPEND atom base pair per line
Example:
# use net-mail/ssmtp as the default mta
virtual/mta net-mail/ssmtp
# use app-dicts/aspell-en as the default dictionary
virtual/aspell-dict app-dicts/aspell-en |

The mysql virtual is a new style virtual. All the old style virtuals are gone from the tree.
| vitual/mysql-5.1.ebuild: | RDEPEND="|| (
=dev-db/mysql-${PV}*[embedded=,minimal=,static=]
=dev-db/mariadb-${PV}*[embedded=,minimal=,static=]
)"
|
since mysql is the first one listed, it will pick it first. You need to manually emerge mariadb first so it can resolve it as the dep instead (installed optional dep wins).

Yes, those /etc/portage/profile/virtuals is no longer supported with new style virtuals.
Please file a bug/bugs for them.
