I have a web page which I developed for how to use a high-performance disk driver under Debian for the s390 platform. As it turns out, the high performance driver doesn't work with the type of disks supported by the Debian installer; so that means installing to one type of disk and then migrating to another type of disk after the install. Perhaps the migration procedure documented therein can be adapted to your purposes. The low-level formatting and partitioning steps are quite different on this platform from PCs. But creating the file systems and copying the data are relatively platform independent. You'll have to discern what is platform specific and either disregard or adapt it. But anyway, here's the link, in case you find it useful. http://www.wowway.com/~zlinuxman/diag250.htm -- .''`.

The option for cp even has exactly the same name as the option for rsync, namely "-x" or "--one-file-system". -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkvDqfcACgkQ+VSRxYk4409OSwCfQUbrWYLwoNQME/98sIdFSzNd Y+4AnRkojnSeHm77jVJzPi1g497+U+Yp =VbRe -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

That indeed makes sense, but I was to lazy to look in the manpages. I guess I am a rsync fanboy ;) Sjoerd |
