Re: [REPOST!] Split out e2fsprogs sublibraries

Great idea, there has been some confusion in the past over uuid
package vs libuuid in e2fsprogs

There is also the similarly named uuid which has caused some confusion
in the past.

I have a number of packages that depend on libuuid which will need to
be updated.

With the auto provides in most rpms I don't think they should need a
rebuild straight up as they depend on libuuid.so.1 as opposed to a
specific package name but only going forward so in the short term
there shouldn't be breakages?
