[gentoo-server] mysql upgrade process

[Ben Munat]

I was thinking about diverging from the mysql upgrade process described at

http://www.gentoo.org/doc/en/mysql-upgrading.xml

by one small bit. I'd rather not have the half-hour or so downtime while compiling mysql, 
so I was hoping to (after backing up my data) "emerge --buildpkg mysql" to get the 4.1 
package all built. Then I'd stop mysql 4.0, unmerge it, "emerge --usepkgonly mysql" and 
restore my data.

However, I have a feeling it won't work because the 4.1 ebuild probably checks for the 
existence of 4.0 on the system. If that's the case, could I maybe do the "export 
MYSQL_STRAIGHT_UPGRADE=1" step from the straight upgrade instructions?

Of course, I'm not keen on doing any of this if there's some reason that vpopmail is not 
getting rebuilt with libmysqlclient.so.14... anyone have any luck with that yet?

thanks,

b
