ro-mounted file partitions and rpms

[Tony Earnshaw <tonni hetnet nl>]

Hi list,

Inspired by a very recent (irate) Suse post to the Courier IMAP list, I 
ask the following of the main vendor packages here.

Quoting a line of the posting out of context, the @suse.de poster 
writes, complaining of the Courier install file hierarchy:

"/usr might be mounted read-only according to FHS, and is not expected 
to contain variable or machine-specific data." This in respect to 
Courier IMAP certificate .pem files within /usr that have to able to be 
be generated on the fly.

Ok, the standard %{prefix} for rpm installs is /usr. AFAICS, at no stage 
during an rpm install is there ever any attempt to mount and remount 
/usr (or any other file hierarchy which might be mounted ro) to enable 
installation. How does an rpm install cope with ro files systems such as 
/usr?

Best,

--Tonni
